How to Change a TACACS Password in a Cisco 3750

September 9 2011 , Written by ciscorouterswitch

TACACS stands for Terminal Access Control Access-Control System. It lets administrators manage passwords and configurations on a number of routers using a single server. In larger enterprises, where there are many routers required to maintain the infrastructure, updating an entire network's configuration from a single reference point makes managing hundreds of systems a quick task. You will need to authenticate with the TACACS server before deploying a new configuration.

Instructions

1. Log into the Cisco 3750 using your SSH client or a direct cable link. Supply your administrative user name and password and connect to the IP address specified by your system administrator.

       

2. Type "Tacacs-server host <ip>." Replace <ip> with the Internet Protocol address of the TACACS host server.

       

3. Type "password <password>" where "<password>" is your current TACACS password.

       

4. Type the command "tac_plus_executable -P -C <config path>." This command will invoke the TACACS server and set it into password replacement mode. The -C parameter will allow you to specify a configuration file that contains a list of user names and passwords authorized to access routers on the TACACS network.

How to Configure a Cisco Router

September 8 2011 , Written by ciscorouterswitch Published on #Cisco Routers

The process of configuring a Cisco brand router involves the invoking of the User, Privilege, Configuration, Interface, and Line modes. These various modes are utilized to allow the definition of information relative to the password, hostname, IP address along with the subnet mask, clock rate, and line configurations that will dictate the behavior of the router device. Prior to powering up the router to undertake its configuration, it is necessary to first set up a terminal emulation application to 9600 baud with eight data bits, no parity and single bit stop. This process will also be used to define the type of protocol that will be implemented across the network which will be supported by the router that will be connected to the computer system’s serial port.

router-Cisco-rear-panel.jpg
 

 

Materials Needed: 

- Cisco router
- Ethernet cable
- terminal emulator utility like HyperTerminal
 

 

Step 1

The initial steps to the configuration process after setting up the terminal emulation program is to power up the Cisco router and wait for the message prompt to be displayed.

 

Step 2

To implement basic configuration, type at the command prompt the text 'Enter Privilege Mode' followed by the 'Router > enable' command.

 

Step 3

When the cursor appears; type the 'Enter Configuration Mode' and the Router# configuration terminal command.

 

Step 4

In order to implement password protection when accessing Privilege Mode, the 'Router(config)# enable password p@ssw0rd' and the 'Router(config)#enable secret s3cr3t' commands must be issued.

 

Step 5

The 'Router(config)#hostname myrouter1 [Set the hostname to myrouter1]' instruction provides the user with a way of defining the Hostname or the Router Name that will be broadcasted across the network.

 

Step 6

The commands to configure the Ethernet port consists of the 'myrouter1(config)# inte f0/0 [Enter Ethernet Interface Mode ( f0/0 for interface1, f0/1 for interface 2)]', 'myrouter1(config-if)# ip add 192.168.0.1 255.255.255.0 [Set IP address and subnet mask]', and 'myrouter1(config-if)#no shut [Active the port]' commands. These commands will allow the smooth flow of network traffic on the defined communication portals.

 

Step 7

Configuration of the Serial Port makes use of the 'myrouter1(config-if)#inte s 0/0/0 [Enter Serial Interface Mode]', 'myrouter1(config-if)#ip add 192.168.20.1 255.255.255.0 [Set IP address and subnet mask]', and 'myrouter1(config-if)#no shut [Active the port]' commands.

 

Step 8

It is also necessary to set the bandwidth that will be used by the router. This is commonly done by using the 'myrouter1(config-if)#clock rate 1000000 [Set the bandwidth to 1Gig]' and 'myrouter1(config-if)#exit' commands.

 

Step 9

The Secure Console is defined by using the 'myrouter1(config)#line con 0', 'myrouter1(config-line)#password c0ns0l3', 'myrouter1(config-line)#login', and 'myrouter1(config-line)#exit' commands. These instructions will configure the access credentials that will be used to bring up this utility.

 

Step 10

The auxiliary password that will be used to connect any modem device to the router hardware via the remote connection console may be done by using the 'myrouter1(config)#line aux0', 'myrouter1(config-line)#password auXo', 'myrouter1(config-line)#login', and 'myrouter1(config-line)#exit' instructions.

 

Step 11

Securing the login process via SSH or Telnet processes is done by using Virtual Terminal Password. The commands 'myrouter1(config)#line vty 0 4', 'myrouter1(config-line)#password v1rtu@1', 'myrouter1(config-line)#login', 'myrouter1(config-line)#exit', and 'myrouter1(config)#exit' are executed within the Secure VTY line utility.

 

Step 12

To finish the configuration process, the settings must be saved either by using the 'myrouter1#wr me' or 'myrouter1#copy run start' commands.

Four Main Types of Cisco Memory in Cisco Hardware

September 6 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

Cisco is a large manufacturer of networking hardware, inter-network operating systems, network routers, switches and other similar devices. The actual design and layout of each product controls what types of Cisco memory can be used in the system device. This also influences what functions the memory serves in the system.

Cisco has four main types of memory in its hardware.

 Cisco-memory.jpg

Dynamic Random Access Memory

Dynamic Random Access Memory (DRAM) is designed to work with computer systems that have two device requirements. One requirement would be the job that the processor memory performs. This is an operation that allows for exclusive memory access by the CPU, which it uses when executing software running on the Cisco IOS platform. Critical data such as configuration settings or routing tables are stored in the processor memory. The second requirement would be the function that the shared memory performs. This takes any and all data that comes in and out of the system and buffers it to what is called the packet memory. It is sent there before being transmitted over the network interface.

 

Erasable Programmable Read-Only Memory

Erasable Programmable Read-Only Memory (EPROM) is a memory system often unchangeable by consumers. When the system is being manufactured, it is one of the last stages left to complete. EPROM memory is installed with two components. One is the boot loader, which allows a system that may fail to find a bootable image in the flash memory and allow an alternate boot option. The second component is a ROM monitor, which comes with a user interface and options for troubleshooting any possible failures of the ROM chips.

 

Non-Volatile Random Access Memory

Non-Volatile Random Access Memory (NVRAM) performs the duty of storing configuration information used by Cisco IOS during booting and start-up. The NVRAM allows the functionality of the Cisco Software Configuration Register (SCR), which sole function is allow a device to be booted and chosen from the multiple IOS images stored in flash memory.

 

Flash Memory

Flash memory has the widest variety of uses from all the Cisco memory types. The primary use for flash memory is to store bootable IOS images from which the system can define and use to start up. Most of the computers have installed the onboard flash memory the device uses to boot, but in some higher end systems, they can have the ability to boot up from a image stored on a removable flash memory card.

How to Reset a Cisco 3900 Router

August 31 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

Cisco markets the 3900 Series Integrated Services Router, or ISR for short, as their cutting edge option in office network technology. The unit offers an upgradable motherboard. This allows owners to update hardware as more powerful options become available without having to purchase a new router. Cisco also appeals to environmentally conscious consumers with their EngeryWise dual power supplies, which lower electricity costs and support essential redundancy requirements. It is occasionally necessary to reset this powerful networking device, restoring it to factory default settings.

http://www.router-switch.com/productimages/Routers/l/cisco3945.jpg

 

 

Two Metods to Reset a Cisco 3900 Router

Method One

1. Enter "config-register 0x2102" from the router's command prompt window. This gives you access to global configuration mode.

       

2. Enter "show version." The response should read:

router# configure terminal

router (config) #config-register 0x2102

router (config) #end

router#

Repeat the "show version" command.

The response should now read "will be 0x2102 at next reload."

       

3. Enter the command "write erase." This will erase the current start-up configuration.

       

4. Reload the software by entering the "reload" command. Do not save when prompted.

The system display should read:

router#reload

System configuration has been modified. Save? (yes/no): n

Proceed with reload? (confirm)

Confirm that you want the reload to proceed.

       

5. Wait for the reload. The dialog box will read:---System Configuration Dialog---

Would you like to enter the initial configuration dialog? (yes/no)

The router has been reset.

   

Method Two

1. Enter the command "config-register 0x2142."

The response should read:

Router (config)#config-register 0x2142

Repeat the "show version command."

The response should now read "will be 0x2142 at next reload."

       

2. Reload the software by entering the "reload" command. Do not save when prompted. The system should read:

router#reload

System configuration has been modified. Save? (Yes/no): n

Proceed with reload? (Confirm)

Confirm that you want the reload to proceed.

       

3. Wait for the reload. The dialog box will read:

---System Configuration Dialog---

Would you like to enter the initial configuration dialog? (Yes/no) Enter "no."

     

4. Change the configuration register setting to 0x2102. Enter "config-register 0x2102." Enter "write memory." This will overwrite the running configuration.

       

5. Enter the "reload" command. The system configuration dialog will appear again. The router is reset.

Easy Steps to Enable Cisco Switches

August 30 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Cisco switches are network devices used on data networks to facilitate data transport. For a Cisco switch to be integrated into a network, it must be enabled before custom network configurations can be made. To enable a switch for network use, the switch will need to be named and secured with a privilege execution mode and console password.

 

Things You'll Need

Cisco Catalyst 2960 switch or other Cisco switch capable of IOS command line configuration (Cisco 2940, 2950, 2955 and others), Computer monitor

http://www.router-switch.com/productimages/Switches/v/ws-c2960-24tt-l.jpg

 

How to Enable Cisco Switches       

1. Start the Cisco switch. Be sure that your monitor terminal is interactive with the switch so that you will be able to see the Cisco IOS command-line interface appear on start-up and configure the switch. Once started, the "Switch>" prompt will appear in the command-line interface.

       

2. Configure the switch with the host name network1switch. At the "Switch>" prompt in the IOS command line, type "enable," then press "Enter." The "Switch" prompt will appear. Type "#config terminal" and press "Enter." The "Switch (config)" prompt will appear. Type "#hostname network1switch" and press "Enter." The switch is now named "network1switch" and the next prompt will now read "network1switch (config)."

       

3. Set the privilege execution (exec) mode password to 123catalyst. At the "network1switch (config)" prompt, type "# enable password 123catalyst" and press "Enter." The privilege exec mode password is now 123catalyst. The next prompt will read "network1switch (config)."

       

4. Set the console password to 123cisco. At the "network1switch (config)" prompt, type "#line console 0" and press "Enter." The "network1switch (config-line)" prompt will appear. Type "#password 123cisco" and press "Enter." The console password is now set to 123cisco and the next prompt will read "network1switch (config-line)."

       

5. Configure the console line to require a password at log in. At the "network1switch (config-line)" type "#login" and press "Enter." The switch console line will now require a password at log in. The next prompt will be "network1switch (config-line)."

       

6. End the command-line configuration session. At the "network1switch (config-line)" prompt, type "#end" and press "Enter." The command-line interface session will now end. The new Cisco switch is now named network1switch with a privilege exec mode password of 123catalyst. This switch is further secured by requiring a console password of 123cisco at log in. This switch is now ready for further interface configuration and customization for your network.

 

More tips:

Many Cisco switches require users to use the Cisco IOS command-line interface for device configuration. Familiarity and confidence with working in a command-line environment will enhance an administrator's ability and productivity when configuring many Cisco network devices.

Why Cisco Cius Survives While HP's TouchPad Fails

August 25 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

Competition between HP and Cisco has reached epic heights in the past few years, from data center wares to tablets. Here's why Cisco Cius survived even as HP pulled the plug on its TouchPad tablet.

 

With the TouchPad experiencing one of the shortest product lifecycles in IT in the last few years (some argue the Microsoft Kin had a shorter lifespan, but it did get a temporary resurrection), analysts are pointing the finger for its untimely death at a major switch in HP’s strategic focus, product launch delays and confusing marketing. With the TouchPad officially on the chopping block seven weeks after launch, what’s in store for other business tablets, most notably the Cisco Cius?

 

The simultaneous announcement that HP would be selling off its PC unit really shows a difference in the vendor’s focus since the days of Carly Fiorina and Mark Hurd, both of which were focused very much on the PC business. Current CEO Leo Apotheker, however, is a different kettle of fish, said Charles King, principal analyst at Pund-IT. King noted that Apotheker is a data center and software guy, and with terrible sales of the TouchPad in the first few weeks after launch, there was clearly a willingness to abandon the product.

 

“Certainly patience wasn’t the order of the day,” King said.

 

According to Rob Enderle, president and principal analyst of Enderle Group, HP’s acquisition of Palm delayed the release of the TouchPad. Designed to compete with the first generation of the Apple iPad, by the time it hit the market in July, it already seemed out of date and the consumer market had already spoken. Meanwhile, other tablets being released right now were designed to compete with the iPad 2.

 

Mixed marketing messages also may have contributed to the early demise of the TouchPad, Enderle said. Was it a consumer tablet or a business tablet?

 

The TouchPad was kind of a mixed beast. It didn’t have a lot of business attributes to it. The advertising was clearly focused on the consumer. It got lost,” Enderle said.

 

It seems clear that mistakes were made, but what does this mean for business tablets entering the market, most notably one of HP’s biggest rivals, Cisco and its Cius tablet?

 

It’s likely to be good for Cisco, said Michelle Warren, president of MW Research & Consulting. Although there has been a lot of iPad adoption by executives in the business world, IT departments are struggling with managing and securing the devices. They’re looking for an alternative, and the Cisco Cius, which was designed specifically for enterprises in mind (Cisco’s own messaging is not aimed at the consumer at all), is getting some notice. Warren said the Cius is becoming a popular choice, even though it hasn’t even launched yet. When the Cius does launch, it will have one less competitor in the business tablet space, and it’s unlikely Cisco will drop the Cius product line, she said.

 

“There is a need for it in the enterprise space,” Warren said. At the very least, it was designed for enterprise apps and will be easier to manage and secure.

 

However, the question regarding all tablets that sell at or above the iPad's price point is whether they can be viable in an Apple-dominated business, King said. There is likely more leeway for business tablets like the Cius, he added.

 

“Apple is very clearly consumer-focused, although the company insists the iPad and iPhone are ready for the enterprise. I think that’s arguably incorrect, but it may have been a problem with the TouchPad because HP was trying to market it as being used by both businesses and consumers,” King said.

 

To its credit, Cisco has been very clear about its intentions for the Cius, he said. Its primary strengths are in enterprise computing and collaboration.

 

“The environment right now for tablets is extremely challenging, but I think Cisco is obviously in a place where they’re working very hard to curtail costs and reduce red ink,” King said. “If the Cius was really bleeding money, it could be destined for the boneyard, but I think what the company has done to date, at least, is get rid of those products that weren’t within the purview of its enterprise focus, like getting rid of the Flip and some of its other consumer-centric product areas. I think the Cius probably resonates enough with the company’s overall enterprise-centric mandate that it would make less sense for Cisco to put down production on that than it would on something on the more consumer-centric side of the business.”

Password Recovery Procedure for the Cisco 2900 Integrated Services Router

August 24 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Perform these steps in order to recover your password:

1.     Either switch off or shut down the router.

2.     Remove the compact flash that is on the rear of the router. This image shows the rear of the Cisco 2951 router:

For more information, refer to Back Panel Slots and Connectors on the Cisco 2921 and 2951 Routers.

the-rear-of-the-2951-router.jpg

3.     Switch on the router.

 

4.     Once the Cisco router is on Rommon mode, reinsert the compact flash.

5.     Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.

This step bypasses the startup configuration where the passwords are stored.

6.     Type reset at the rommon 2> prompt.

The router reboots, but ignores the saved configuration.

 

7.     Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.

8.     Type enable at the Router> prompt.

You are in enable mode and should see the Router# prompt.

9.     Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.

Warning:  Do not enter copy running-config startup-config or write. These commands erase your startup configuration.

 

10.   Issue the show running-config command.

The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, and console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.

11.   Type configure terminal.

The hostname(config)# prompt appears.

12.   Type enable secret <password> in order to change the enable secret password. For example:

   
 13. hostname(config)#enable secret cisco 
   

14.   Issue the no shutdown command on every interface that you use.

If you issue a show ip interface brief command, every interface that you want to use should display up up.

15.   Type config-register <configuration_register_setting> . Where <configuration_register_setting> is either the value you recorded in step 2 or 0x2102 . For example:

 16. hostname(config)#config-register 0x2102 
   

17.   Press Ctrl-z or end in order to leave the configuration mode.

The hostname# prompt appears.

18.   Type write memory or copy running-config startup-config in order to commit the changes.

Cisco: Tales from the trenches

August 18 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

14 years ago when Chuck Robbins started at Cisco, “you had a desk and you put your name outside the desk.” Now after more than a decade, the work style at the company has changed nearly beyond recognition, becoming incredibly accommodating to remote teams. And Robbins has thrived in this innovate environment, rising to the position of senior VP and running the organization’s sales team for the Americas.

 

What lessons has Robbins learned from leading through this transition at company that was not only an early adopter of flexible working, but which also builds a number of remote work solutions? He shared his wisdom with WebWorkerDaily.

 

Talent

Do experienced managers of co-located teams just magically make a smooth transition to a virtual workstyle? Not according to Robbins, who is a big believer in training, and not just on the technical challenges of web work.

 

“The technology actually tends to be the easiest part of this whole thing,” he told us, adding that the success of web work is often inhibited by “cultural acceptance by the leadership team that this is how we operate and it’s OK. Some companies equate productivity with being in the office, so I think, first of all, we have to make sure that we provide our leadership with education on things around, how do you manage a remote workforce effectively? What are the things you need to do differently when you can’t walk down the hall and grab them? We give that kind of training.”

 

Tools

Robbins’s pro-training philosophy extends to tech tools as well. He explains that team members are also trained in how to make the best use the of video conferencing solutions Cisco offers, answering questions like, “What sort of things should you be thinking about when you’re presenting to a customer over video and you’re not in the room and everybody else is? Or if you’re in the room and somebody else is remote, how do you make sure you continue to engage them?”

 

Video may play a big role for Robbins’s team, but email doesn’t. “Email is becoming the least favorite mode of communication with our team,” he said. Instead of sending individual messages, Robbins’s employees have “a new platform that we actually designed called Quad. It’s named after the college campus quad where everybody gathers. Think of it as Facebook for enterprise. People can build communities around different topics and they have their profile and their status and then we have integrated instant messaging.”

 

“New technology that enables single number reach for our sales organization,” is the final piece of the puzzle for Robbins’s team. “No matter where you are somebody doesn’t have to keep up with what phone numbers to dial. They dial your office and it rings whatever device you need it to ring,” he said.

 

Tips

In addition to tech and training, Robbins relies on an outcome-based management style to keep his team running smoothly. To succeed as the manager of a virtual team, “you have move to outcome-based performance, and to the extent that you can, outcome based compensation,” he advises. “That cultural thinking that, if you’re at your desk from eight to five, than you’ve been productive is no longer valid, so you’ve got to figure out how you create outcomes and metrics where you can determine success.”

 

All of these pieces have come together to create a deep change in attitudes towards flexible working at Cisco, Robbins concludes. “When we first started working from home, for some reason we didn’t want people to know we were working from home. You didn’t want the dog to bark or the kids to come and say something. You were always trying to mute if the dog was coming around. Today, if you’re working from home and your kid walks in, you tell them to say hello to whoever you’re talking to on the other end because it’s such an accepted thing.”

 

Think something similar won’t be coming to your company anytime soon? Think again, insists Robbins. “Any companies that don’t think they’re going to have to buy in to this approach, I think they’re going to be in trouble. For the first time ever we have conversations with companies about how to build their remote worker infrastructure and their collaboration capability in a way that will enable them to recruit the next generation workforce, because they believe that will be a retention issue. It’s become a strategic recruiting tool for many companies.”

Why Should We Care about Cisco 3560-E Series Switches

August 17 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Demands on IT infrastructure are changing. Improving network efficiency and articulating the clear value network infrastructure brings to your business have never been more important. The Cisco Catalyst 3560-E Series access and aggregation switches offer networking solutions that can expand with your business without costly upgrades or network disruptions, maximize your network investment, and decrease network costs over time.

 

Increased desktop bandwidth, expanded use of real-time communication and collaboration applications, and the desire to maximize networking investments are changing the way network solutions are designed and implemented. Supporting Gigabit Ethernet to the desktop often requires 10 Gigabit Ethernet connections between the access and aggregation layers to be able to maintain a quality experience for users.

 

These deployments can sometimes face space constraints. Voice-over-IP (VoIP) phones, security cameras, and other devices are requiring Power over Ethernet (PoE) support in networking devices. Purchasing a network solution today that grows with your business and network needs can help ensure your company’s competitiveness and success for tomorrow.

 

10 Gigabit Ethernet Uplinks and the Cisco TwinGig Small Form-Factor Pluggable Converter

The Cisco Catalyst 3560-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications, relieving congestion and helping ensure smooth delivery of data. The TwinGig converter (see Figure 2) converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports.

 

Power over Ethernet

The Cisco Catalyst 3560-E Series can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. With the introduction of Enhanced Power over Ethernet the 3560-E Series can scale beyond 15.4W per port delivering maximum solution simplicity for 802.11n access point deployments.

 

Redundant Power System

The Cisco Catalyst 3560-E Series Switches support the Cisco Redundant Power System 2300 (Cisco RPS 2300). The Cisco RPS 2300 (Figure 3) increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3560-E switches at the same time. A power supply can be replaced while the switch is being powered by the Cisco RPS 2300.

 

Cisco Catalyst 3560-E Series Switches

Cisco Catalyst 3560-E Series Switches are an enterprise-class line of standalone access and aggregation switches that facilitate the deployment of secure converged applications while maximizing investment protection for evolving network and  application requirements. Configurations for the Cisco Catalyst 3560-E access switches include 24 and 48 ports of 10/100/1000 Ethernet with dual 10 Gigabit Ethernet ports. Power over Ethernet is available on both the 24-port and 48-port models and can deliver IEEE 802.3af 15.4W class 3 PoE on all ports simultaneously. Combining 10/100/1000 and PoE configurations with 10 Gigabit Ethernet uplinks, the Cisco Catalyst 3560-E enhances worker productivity by enabling applications such as IP telephony, wireless, and video.

 

The Cisco Catalyst 3560-E Series aggregation solutions - the Cisco Catalyst 3560E-12D, a 12-port 10 Gigabit Ethernet aggregation switch, and the Cisco Catalyst 3560E-12SD, a 12-port SFP Gigabit Ethernet aggregation switch with 2 10 Gigabit Ethernet uplink ports, deliver secure nonstop unified network services and versatile connectivity in a one-rack unit (1-RU) form factor for space- and power-constrained environments, enabling businesses to reduce total cost of ownership while maximizing investment protection.

 

Cisco Catalyst 3560-E Series highlights:

    Cisco TwinGig converter module for migrating uplinks from Gigabit Ethernet to 10 Gigabit Ethernet

    PoE configurations with 15.4W of PoE on all 48 ports

    Industry first portfolio to scale beyond 15.4W per port delivering maximum solution simplicity for 802.11n access point deployments

    Access switch models have modular power supply with externally available backup

    Dual redundant modular power supplies and fans for Cisco Catalyst 3560E-12D and Cisco Catalyst 3560E-12SD aggregation switches for nonstop operation

    Multicast routing, IPv6 routing, and access control list (ACL) in hardware

    Out-of-band Ethernet management port along with RS-232 console port

 

Benefits of the Cisco Catalyst 3560-E

Scale your network as your business grows: With the TwinGig converter module, you can convert the 10 Gigabit Ethernet interfaces into dual SFP ports in the access and aggregation layers, allowing you to migrate from Gigabit to 10 Gigabit Ethernet when your business demands change without changing network devices. The Cisco Catalyst 3560E-12D also enables the aggregation of up to 12 10 Gigabit Ethernet links within a compact 1-RU form factor in space-constrained environments. Decrease network costs over time: the Cisco Catalyst 3560-E delivers full PoE (15.4W) on every 10/100/1000 port so that as your needs for PoE and Gigabit Ethernet grow, you are positioned to support them without costly upgrades or complete network replacements.

Cisco lower Profit, but innovation continues

August 16 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

In the fiscal third quarter, Cisco’s reported net income fell 18 percent to $1.8 billion or 33 cents a share, from $2.2 billion, or 37 cents, in the year-ago quarter.

 

Stiff competition comes from companies like Juniper Networks and Alcatel-Lucent for corporate customers, including telecommunications companies, hospitals and universities. Meanwhile, Spending by government agencies was particularly weak for Cisco, declining 8 percent in the quarter.

 

Cisco faces additional pressure because of evolving markets and a failure to adapt. Many networking products are now specialized based on the kind of customer, a development that Cisco was late to embrace.

 

How to do? What strategy will cisco take?

 

In an effort to reverse the slide, John T. Chambers, Cisco’s chief executive said that he planned to cut an unspecified number of jobs and potentially eliminate or scale back additional products to lift Cisco’s growth. With about 73,000 employees, the company has already eliminated 550 jobs, offered employee buyouts and killed the Flip video camera as part of his month-old turnaround plan.

 

In addition, Mr. Chambers would take additional steps to streamline Cisco by revamping its complex management structure, which had executives serving on a patchwork of “councils.” Instead of encouraging cooperation, the councils created additional bureaucracy.

 

What’s more, Mr. Chambers e has begun a series of changes intended to focus Cisco on its core products(Cisco router and Cisco switches). He has scaled back the company’s consumer division, which included the Flip video camera, but others may be affected. Cisco said that it expected to save $1 billion over the next 12 months from its job cuts and streamlining. 

 

But the turnaround is expected to take time. It’s a company that has pockets of weakness, but it also has pockets of strength. Let wait and see what happens!
