To simulate a small branch office, the Cisco ISR 1941W was configured as a branch router serving a dozen employees. Primary network connectivity was established via a public internet connection with a DMVPN (Dynamic Multipoint Virtual Private Network) encrypted link to corporate headquarters. A 3G wireless data connection was setup for branch redundancy in the event of a primary WAN link failure. The Cisco ISR 1941W was also configured to support wireless utilizing 802.11n radio to extend the corporate wireless network into the branch office as well as provide guest network connectivity for visitors to the office. Security features–Zone Based Firewall, Cisco IOS IPS and content filtering were activated. The Voice services were provided by a headquarters-based CUCM (Cisco Unified Communications Manager).

 

Medium Branch Office Cisco ISR 2911 Platform

A medium branch office deployment was simulated using a Cisco ISR 2911. This branch scenario supports about 25 users. Primary and backup network connections were to be provided by two separate Ethernet WAN links. An IP WAN provided primary network connectivity with a DMVPN secure connection serving as backup to corporate headquarters. Security features – Zone Based Firewall, Cisco IOS IPS were activated. Voice services were provided by a headquarters-based CUCM with local POTS (Plain Old Telephone Service) access from the Cisco ISR 2911. Cisco Unified SRST (Survivable Remote Site Telephony) was supported to provide redundant local call control in the branch offices in the event the central CUCM is unreachable. Telepresence and video are also supported and enabled for this deployment.

 

Large Branch Office Cisco ISR 2951 Platform

Example to Set up DDNS on a Cisco IOS Router

March 19 2013 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

How to set up no-ip.com DDNS on your Cisco IOS router that actually works!

 Internet-Cartoon.png

Normally we try to setup static IP addresses for our managed routers. However in this case the router was residential and in Singapore. Getting a static IP address was actually impossible.

 

I started the project by researching DDNS providers. Many of the DDNS providers that were free in the past are no-longer free. However no-ip.com still offers a free version of DDNS. The free version is under the section of their website for personal. At this time I could not find any statements on their site restricting the service to personal use. Here is a link to their site.

 

This procedure is easy to perform but due to lack of proper documentation and a lot of incorrect documentation, including that in the no-ip.com knowledgebase, it is more difficult than it should be.

 

This article assumes you have a basic knowledge of Cisco routers and know how to get into config mode and how to save your configuration.

 

There are three primary steps to setting up DDNS on a Cisco IOS router.

  1. Set up and confirm DNS resolution works.
  2. Set up a DDNS method to be called.
  3. Set up the external DHCP interface to call the DDNS update method.

 

Set up DNS resolution.

Confirm your router can ping something by name properly. A simple 'ping google.com' is an effective test. If it does not work you can setup you router DNS to use Google's public DNS servers with these two config lines:

  • ip dns server
  • ip name-server 8.8.8.8 8.8.4.4

 

Set up the DDNS method.

The method tells the router how to contact the DDNS provider, login and send the proper update command. It also controls the minimum and maximum time between DDNS updates. Do not set the maximum time too short. Many DDNS providers will lock you out if you update too frequently. I typically use one day but you need to check with your provider.

 

Create and name the DDNS update method.

  • ip ddns update method ddns-noip

Set the update mode to HTTP

  • HTTP

 

Create the ADD URL. The URL contains some special characters mainly the'?' that is problematic to enter because the router interprets it as a call for help. Use CTRL-V just before typing the '?' and the router will place it properly. Replace [username] and password with your no-ip credentials. You will need to enter your username as an email address including the '@' 

<h>&myip=<a> is a macro replaced by the router during the update with hostname and ip. i.e. hostname=myhostname.no-ip.org&myip=4.2.2.2'

  • add http://[username]:[Password]@dynupdate.no-ip.com/nic/update?hostname=<h>&myip=<a>

update minimum every 5 minutes maximum 1 day.

  • interval maximum 1 0 0 0
  • interval minimum 0 0 5 0

 

 Apply the update to the external DHCP interface.

Select the external interface and apply the update command to call the method you just created. For the Cisco 871 router used in this configuration it is FastEthernet 4. Replace it with your proper interface. For PPPoE it is likely interface Dialer 0.

 

Substitute your DDNS method name and the hostname to update at your DDNS provider with your specific details..

  • interface FastEthernet4
  • ip ddns update hostname [DDNS hostname]
  • ip ddns update ddns-noip

 

Debugging.

Unfortunately I have not figured out a way to force a DDNS update NOW. What you can do is set your maximum update time short like 5 minutes. Turn on debugging with: debug ip ddns update.

 

You will get some very useful debug information. Make sure all the parameters are correct on the calls.

 

You may need to reload your router. I have round that changing the add command did not update properly after some changes until after a reload.

 

Sample Debugging Output for a working update.

Cisco Branch Routers’ New Performance

March 14 2013 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Public and private cloud drives new upgrade

Cisco ISR line to get WAN optimization, application performance monitoring, WAN path management and security license

 

Cisco this week extended the software capabilities of its ISR branch routers with previously separate security and application performance features, including WAN optimization.

 

Cisco rolled out the ISR-AX line, which takes existing ISR G2 models 3900, 2900 and 1900 and adds a security software license for VPN, firewall and intrusion prevention, as well as software-based Wide Area Application Services (WAAS) WAN optimization, application visibility and control, and WAN path management. Also included is the Cisco Services-Ready Engine processing hardware or additional random access memory to run the software.

Cisco-Branch-Routers.jpg

Cisco's ISR-AX line adds security, application performance and WAN optimization features to existing models.

Cisco says it is doing this because with the advent of application centralization in data centers or hosted in the cloud, the branch office router needs to evolve to become a Layer 2-7 application service delivery engine. Customers at remote sites need applications to run faster, and require network wide visibility and control for accelerated application deployments, performance monitoring and problem resolution without the need for additional devices, Cisco says.

 

Indeed, Cisco says software will be the way it delivers its WAAS WAN optimization product to the branch office. The physical hardware appliance will be targeted predominantly at data centers where WAN optimization requires scale, company officials said.

 

And to catalyze adoption of the ISR-AX, Cisco says it is 20% to 35% less expensive than a stand-alone WAN appliance for the branch office. Cisco is offering the AX line at up to 45% less than non-AX 3900s, 2900s and 1900s.

 

The ISR 3900 is at the center of a current contract controversy between Cisco and the state of West Virginia.

 

The ISR line has 500,000 customers worldwide. Cisco had a 77% share of the $855 million enterprise router market and an 84% share of the $671 million enterprise access router market in the third quarter of 2012, according to Dell'Oro Group. It's aiming the ISR-AX squarely at Juniper and Riverbed, which recently entered into a technology licensing deal, even though Dell'Oro cites HP, Adtran and OneAccess as Cisco's closest competitors in access routing.

 

Asked why HP, for one, wasn't on Cisco's competitive radar for the ISR-AX, a company spokesperson stated in an email:

 

"While HP has the ability to host applications, they do not have an integrated offer for application performance monitoring, WAN path selection or optimization. We realize they have some APM partners and work with Riverbed, but we view that as [a] gap since [they] do not solve the problem directly, which creates integration, management and cost challenges for customers. Much like Juniper, they have too many gaps to solve the application challenges our customers are facing today with virtualization, cloud and BYOD."

 

HP didn't respond to a request for comment by press time.

 

But Juniper did respond:

 

"Juniper believes the market is moving towards high speed Ethernet WAN connectivity and the need for WAN acceleration in the branch is decreasing," says Brad Brooks, vice president of business strategy and marketing for Juniper. "Rather than integrate WAN optimization in branch SRX and penalize customers with a higher priced solution, Juniper has partnered with Riverbed, the leading WAN optimization provider, to deliver this service to customers should they require it. Riverbed has continuously maintained their competitive edge where other technologies have trailed behind. This partnership is aligned with Juniper's strategy of offering an open architecture with a growing ecosystem of partners that allows customers to select solutions that best fit their network needs."

 

Brooks also says Juniper's branch SRX router provides application level security and unified threat management, integrated with routing and network security, to eliminate the need for multiple devices and reduce TCO. Juniper also offers an application monitoring solution along with WAN path selection functionality in the branch SRX devices, Brook says.

 

All Cisco 3900-AX, 2900-AX and 1900-AX products are currently available. The 3900-AX is priced from $16,200 to $24,700. The 2900-AX is priced from $3,595 to $12,900, and the 1900-AX costs from $2,945 to $2,995.

 

Cisco says it will soon extend the AX capabilities to the 800 ISR, ASR1000 and CSR1000V routers for teleworkers, enterprise network edge, and data center and cloud, respectively.

Enables onboard automation for fault detection, troubleshooting, and recovering

The Cisco ISR G2 routers provide the network platform for borderless services. As you run more services on your network, you can use IP SLAs to monitor critical network traffic performance indicators, including delay, jitter, and link availability. IP SLAs mimic real-world traffic to proactively identify service-level problems before your users do. Integrating with a broad set of Cisco and third-party NMS applications, IP SLAs set the standard for leadership in proactive performance monitoring.

 

With the Cisco ISR G2 routers, Cisco extends IP SLA capabilities to support 30 different types of simulated traffic, delivering complete performance measurement from application monitoring (HTTP, FTP, etc.) to transport monitoring (User Datagram Protocol [UDP] jitter, Multiprotocol Label Switching [MPLS], etc.).

For more information about IP SLAs, please go to http://www.cisco.com/go/ipslas.

 

Flexible NetFlow (FNF) is the next generation in NetFlow technology. As more services and applications such as business video run in the network, FNF provides the visibility of the network infrastructure needed for optimizing resource usage and planning capacity, reducing operation costs, and detecting security incidents. FNF provides more flexibility and scalability beyond traditional NetFlow by enabling customization of traffic identification, such as source, destination, timing, and application information. Further, FNF provides enhanced network anomaly and security detection to help quickly identify and remediate security risks.

For more information about Flexible NetFlow, please go to http://www.cisco.com/go/fnf.

 

Automation

Cisco IOS EEM is a powerful and flexible feature in Cisco IOS Software that provides real-time event detection and onboard automation. Using EEM, you can program the behavior of the network devices to align with your business needs. EEM supports more than 20 event detectors that are highly integrated with different Cisco IOS Software components to trigger actions in response to network events. You can program these actions using a simple CLI-based interface or Tool Command Language (Tcl) scripting language.

 

Cisco IOS EEM enables network managers to build significant intelligence within Cisco devices to create highly customizable and cost-effective solutions for automated troubleshooting, fault detection and recovery, device configuration, and provisioning.

For more information, please go to http://www.cisco.com/go/eem.

How to Configure DHCP on Cisco 851 or 871 Router?

January 21 2013 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Basically DHCP is a mechanism which assigns IP addresses to computers dynamically. Usually DHCP is a service running on a server machine in the network in order to assign dynamic IP addresses to hosts. All Cisco 800 series models have the ability to work as DHCP servers, thus assigning addresses to the internal LAN hosts. Without a DHCP server in the network, you would have to assign IP addresses manually to each host. These manually assigned addresses are also called “static IP addresses”.

 

In this post we will show you how to configure a Cisco 851 or 871 router to work as DHCP server. The same configuration applies for other 800 series models as well.

Router> enable

 

Router# config t

 

! define an IP address pool name and range
Router(config)# ip dhcp pool LANPOOL

 

! define a network range for the addresses that will be assigned
Router(dhcp-config)# network 192.168.1.0 255.255.255.0

 

! define a dns name to assign to clients
Router(dhcp-config)# domain-name mycompany.com

 

! define a default gateway for the clients
Router(dhcp-config)# default-router 192.168.1.1

 

! define the dns server for the clients
Router(dhcp-config)# dns-server 100.100.100.1

 

! define a WINS server if you have one
Router(dhcp-config)# netbios-name-server 192.168.1.2
Router(dhcp-config)# exit

 

!The following addresses will not be given out to clients
Router(config)# ip dhcp excluded-address 192.168.1.1 192.168.1.10

Cui revealed the exploit he and his colleague Salvatore Stolfo discovered at the San Francisco Amphion Forum. In the demonstration, Cui quickly attached a device he calls the "Thingp3wn3r" to the phone, showing the ease with which it could be physically compromised. Once attached, the Thingp3wn3r circumvents the phone's "off hook switch" which normally disconnects the receiver's microphone when the phone is hung up.

 

The compromised phone, however, kept its microphone active and sent the audio it captured to Cui through a custom-made smartphone app. Though the phone's receive was in its cradle – seemingly inactive – it had effectively become a means to eavesdrop on anything said nearby.

 

The dramatic demonstration was made all the more serious when Cui showed pictures of various high ranking government officials, among them President Barack Obama, with Cisco VoIP phones on their desks. Worse still, PhysOrg reports that once a single phone was compromised with Cui's device the entire network of phones was potentially accessible.

 

Thankfully, this specific vulnerability is no longer viable. In a statement issued by Cisco, the company acknowledged both the vulnerability and their efforts to address it.

 

From Forbes:

"We can confirm that workarounds and a software patch are available to address this vulnerability, and note that successful exploitation requires physical access to the device serial port, or the combination of remote authentication privileges and non-default device settings. Cisco thanks Ang Cui and Salvatore Stolfo for allowing our team to validate the vulnerability and prepare a software patch ahead of the presentation."

 

Forbes also reported that a patch is already available and will be in wide release come January. Concerned users should contact Cisco directly.

 

The presentation, and much of Cui's research, demonstrates that a threat can come from a seemingly innocuous source like a VoIP phone or a network printer. For governments and corporations, simply securing the computers and networks is simply not enough.

Cisco Takes Next Steps to Blend Wired, Wireless Networks

October 8 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Centralizing access control, security, management

Cisco revealed new WLAN access points and controllers, along with its latest steps to blend wireless and wired enterprise networks together.

Cisco-Takes-Next-Steps-to-Blend-Wired--Wireless-Networks.jpg

The networking vendor announced upgraded server applications for access control, network management, and application management across both types of networks. Also new: virtualization options for these infrastructure products; two new lower-priced 802.11n access points for business networks; a new high-end WLAN controller, with a new high-availability feature for Wi-Fi clients.

 

The changes are part of a strategy that the vendor labels "Cisco Unified Access," now being formally announced though it's been featured on the company Website, and talked about with customers, for over a year. The basic idea, according to Cisco marketers, is to centralize and automate policy enforcement, security and authentication, and network management, regardless of how business end users connect to the company network, or with what kind of de-client device.

 

For access control functions, Cisco offers the Identity Services Engine (ISE), unveiled in 2011 as a central point to create and enforce a range of network policies based on the user's identity, role, and devices. [See our "First Look" slide on ISE]

 

A new update to the ISE software adds two features:

+ a Web-based portal, called My Devices," which lets end users register their personally owned devices with ISE, which in turn can enforce for these devices whatever bring-your-own-device (BYOD) policies have been set by the IT group

 

+ Secure Group Access, which lets a network administrator assign users to groups that have a set of pre-defined policies associated with them. New users automatically have these policies applied to them and their devices

 

For security and management across wired and wireless networks, Cisco offers Cisco Prime Infrastructure, also announced last year. It integrates several previously separate tools into one application with a single user interface, spanning both wired and wireless LANs.

 

That software, too, is being updated, adding what Cisco calls application visibility and control. Essentially, Prime can collect data from various sources and tools to create a visual picture of how specific applications are behaving, and of the end user's "network experience" in terms of delays or other quality standards.

 

Cisco also announced for small- and midsized WLANs, which several of these infrastructure products are now available as software that can be hosted on virtual servers: Cisco Prime Infrastructure and Cisco Identity Services Engine, along with Cisco Mobility Services Engine, and a WLAN controller that supports up to 200 access points.

 

The new WLAN hardware products are:

+ Cisco Aironet 2600 and 1600 Series access points, to complement the high-end 3600 Series: the two new products support 802.11n, but each in turn has fewer of the advanced features found in the flagship product. And unlike, the 2600, neither will be able to receive the 802.11ac plug-in module that Cisco recently announced it will ship in early 2013

 

+ Two new high-end WLAN controllers: the 8500 Series is aimed at service providers deploying Wi-Fi networks as adjuncts to wired or cellular network access, or at very large enterprise WLANs. The one-rack unit can manage up to 6,000 access points and 64,000 clients.

 

+ The new controller firmware release now supports what Cisco calls sub-second state-full switchover to improve WLAN availability. In effect, it's a way to shift Wi-Fi clients so quickly to a backup controller that they maintain their application sessions even if their original controller blows up.

Using the Ping Command In The Cisco IOS

August 10 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

The ping command is irreplaceable when it comes to troubleshooting. At some point, you will undoubtedly use this command to solve a networking problem. But how do you properly use this command in the Cisco IOS?

 

The Basics of Ping

The ping command works just like on those old submarine movies. You are on one network device and you “ping” another. When you do this, in your head think of the sound that you heard on those old submarine movies- “PPiiiiiiiiiiiing”. The sound would go out and, on the sonar operator’s-screen, he would or would not see the other submarine. This is exactly how the ping-command in networking, works. Your sonar screen is your Cisco router’s command prompt. Usage of the ping command can be as simple as this:

csc_ping_command_cisco_ios_01.jpg

As you can see in this example, I simply typed ping, and the IP address of the host I wanted to ping. In response, I got five exclamation points that told me that I sent 5 ping packets out, and they were all returned (a complete success).

 

In other words, a ping request is sent out to the remote device, and a ping response is received back, acknowledging the request. As ping uses the ICMP protocol, these packets are technically called ICMP echo request, and ICMP echo reply. ICMP is considered the management protocol for IP. ICMP uses the IP protocol but ICMP is not TCP, or UDP. ICMP does work at Layer 3.

Note that if the ping was not successful, you would have received one of the following (instead of an exclamation point): - “.” = network server timed out - “U” = destination unreachable - “Q” = source quench (destination too busy) - “M” = could not fragment - “?” = unknown packet type - “&” = packet lifetime exceeded Besides the five exclamation points, I was also told that I was sending “5, 100-byte ICMP echoes”. This means that I actually sent five “ping packets” of 100 bytes each. I was told that the timeout was 2 seconds. That means that if a response was not received within 2 seconds, ping would decide that the packet was not going to return at all. This is a safe assumption considering 2 seconds is 2000ms and I am getting pings back in about 36ms. Notice on the last line that the “Success rate is 100 percent”. That is because it says that I sent 5 pings and received 5 ping replies back (that is the “(5/5)”). I was told that the round-trip minimum time for a ping reply to return was 36ms, the average time (of all 5 pings) for a reply to return is 36ms, and the maximum time for a ping reply to return was 40ms. If you have DNS or a local hostname configured, you can use ping with names, like this:

csc_ping_command_cisco_ios_02.jpg

You should know that there are many more types of ICMP traffic other than that used for “pinging” (echo and echo-reply). ICMP is used to redirect hosts to the proper router, to inform hosts that they need to resize their packets, and many types of IP management communications. Each of these types of ICMP packets has a type number (and optionally, a code number). For example, an ICMP echo is type 8. An echo-reply is a type 0. A redirect to another router for an entire network is a type 5, code 0 (with there being possible codes of 0-3). Finally, you can abbreviate ping by only typing “p”. For example: Router# p 1.1.1.1

 

What Else Can I Do With Ping?

Now that you understand the basics, let’s look at an advanced version of ping. Cisco calls this “extended ping”. Extended ping will ask you many questions and “interactively” configure the options for ping. If you have never seen this before, you may be surprised at how many options the ping command can have. Here is an example:

csc_ping_command_cisco_ios_03.jpg

In typing ping, by itself, I was asked a list of questions. I have put a red arrow by each of the questions for which I typed a response. On other lines, I simply pressed Enter to take the default. In this example, I still ping-ed “Router3”. I stuck with the default of 5 ping packets (but could have changed it). I kept the default of a 100 byte ping packet but could have changed this to a ping packet as large as 18,024 bytes. Next, I chose to use the extended options, where I was able to choose the source interface of my ping packets. I also chose verbose output. With verbose output, I was able to see each reply to each ICMP echo that I sent, and the time it took for that reply to return to my router. One thing you may be surprised by, is the first question that asked what protocol you want to ping with. Yes, you can ping with protocols other than IP (such as Appletalk, DECnet, and IPX), but rarely are those protocols used anymore.

 

How Do I Allow Ping Through An IOS Access-list?

Because ICMP is not TCP or UDP, you must specify ICMP specifically when you create an access-list (ACL). Here is an example: access-list 101 permit icmp any any echo-reply In this ACL, we are permitting ICMP traffic from any source, and any destination, as long as it is a reply to an echo request. Many administrators enter the following ACL and expect ICMP to flow through it: access-list 101 permit ip any any This ACL does NOT allow ICMP traffic. To allow ICMP and IP, you need the following two entries in your ACL: access-list 101 permit ip any any access-list 101 permit icmp any any

 

In summary, the ping utility is invaluable when it comes to troubleshooting network issues. While just about everyone has “pinged” something at one point or another, most people don’t know that there is more to ping than the simple ping command. Extended ping on Cisco routers and switches is a very powerful troubleshooting utility. While the ping command does use the ICMP protocol, there is much more to ICMP than just “ping”. Finally, don’t forget to save yourself three keystrokes by abbreviating the ping command with “p”. Over the years, those keystrokes add up!
