Cisco: Enterprise 802.11ac Sooner, Not Later

June 20 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

 

The Wi-Fi giant surprises with an 802.11ac add-on to their popular high-end 3600 AP. Too soon? Perhaps not.

 

Cisco recently briefed me on an interesting product direction they discussed at their latest Cisco Live event, an add-on 802.11ac module for their popular 3600 series of Cisco APs. In addition to being one of the few four-antenna .11n products on the market, the 3600 has a modular architecture that enables the bolting on of additional functionality. Cisco previously announced a security monitor module for off-channel ClearnAir scanning, and the .11ac module will support 3x3:3 1.3 Gbps capability. Both modules are scheduled for availability in 1Q13, a little ahead of my prediction with respect to 802.11ac in the enterprise.802-11ac-wi-fi.jpeg

 

There is little doubt that the as-yet-unfinished 802.11ac standard will eventually supersede 802.11n. This will take many years - at a recent symposium I Chaired for the Boston Section of the IEEE Communications Society, the panel of analysts assembled pretty much settled on 2015 as the timeframe for critical mass for 802.11n in the enterprise - with one thinking it could in fact be much later than that. I'm expecting reasonable numbers of  enterprise-class .11ac products to appear in the second half of next year. As I noted above, I didn't expect an announcement to that effect so soon, and especially from industry leader Cisco. Aggressive? Certainly. But the evolution to .11ac is inevitable, and implementing the functionality in an add-on module eliminates the cannibalization risk that would otherwise be present. Indeed, such might actually spur sales of the 3600 as the technological risk is minimized.

 

The only risk, in fact, might be with respect to cost, as pricing for the module has not been announced. Nonetheless, the benefits of a modular implementations are once again reinforced, even if the assumed success of .11ac remains well off in the future.

How to Troubleshoot Cisco System's Wireless LAN Module

June 18 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

The Cisco Wireless Services Module (WiSM) is part of the Cisco Wireless LAN Controller family. WiSM works with other Cisco appliances to deliver a wireless solution, which supports voice, wireless data and video applications. The Cisco WiSM integrates into the Cisco Catalyst 6500 Series Switch, a Cisco Catalyst 6500 Supervisor Engine 720 and a Cisco 7600 router. Troubleshooting the WiSM is required when the signals are not getting through to the router. The troubleshooting begins with the WiSM connection.

Things You Need as follows:

 

Steps to Troubleshoot Cisco System's Wireless LAN Module

1. Type "enable" to enter the privileged mode of the router or switch. The privilege mode will look like this "Router#"; it is the editor mode in which you enter router commands. This privileged editor mode is automatic. All of the troubleshooting commands will occur in privileged mode. For all of these commands, if there is a period at the end, ignore it.

 

2. Type the command "show version." It is the starting point of any troubleshooting. This displays information relating to the current configuration. One feature displayed is the IOS version running. The WiSM requires a Supervisor 720 on an IOS version 12.2(18). If it does not have 720, or the correct IOS version, there will be problems with the module.

 

3. Type"show module." Use this command to verify that the Cat6k has a WiSM card and the Supervisor 720 engine. It will also show the number of ports on the card.

 

4. Type "show wism status" to verify the location of the WiSM module. This information may be useful in locating other configurations on the module.

 

5. Type "show wism module 4 controller 2 status." This will verify the WiSM status. You will be looking for an "oper-up" information piece to verify the controller's operational status. The module 4 portion identifies the location of the slot in controller 2; it might be different.

 

6. Type "show interface trunk." This will verify that WiSM and VLANs have trunking defined. If you suspect that a problem is occurring with the VLAN, this would be your starting troubleshooting point.

 

7. Type"Show etherchannel load balance." This command will verify the correct load balance algorithm. The algorithm should be src-dst-ip. If this algorithm is not present, use the "port-channel load-balance src-dst-ip" command in config mode to reset it.

 

8. Type "show interface summary" to check the status of the configuration from the WiSM side. Here a summary view of the interface appears. You will see interface name, the port vlan id, the IP address, the type and the application manager.

What Makes LAN Different from WAN?

February 24 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

LANs, Local Area Networks, and WANs, Wide Area Networks, were designed to allow computers to communicate with each other to share files and information.  As network requirements have continued to grow, with video becoming an extremely popular medium to transmit across a network, so too have the sophistication and speed of LAN and WAN technologies. However, both are different in their operation therefore consideration needs to be paid to different factors that help to decide if either of these are going to be used.networking-copy-1.jpg

 

Geographical coverage

A LAN (Local Area Network) covers a small area such as a University campus, a business premises, or even as small as a home network. A WAN (Wide Area Network) covers a much larger geographical scope such as a British country or an American state.  WANS are simply LANS connected together using specialised WAN hardware and WAN technologies.

 

Connectivity

To create a LAN, workstations and printers are connected to a switch using Ethernet cables.  The switch uses algorithms to detect and store details of the devices connected to the switch uses this information to channel data packets out of the correct switch port. The cables used to connect the workstations to switches can be coaxial, copper or fibre.  There is a steady increase in the uptake of fibre optic for LAN connectivity. Computer accessories such as printers can be shared by workstations in the same LAN but not on other LANs.  Each LAN in a WAN therefore will need a separate set of hardware resources.

 

A WAN is an interconnected system of LANS, therefore the WAN link is between each LAN.  To create a WAN, therefore, extra hardware such as a router is needed along with a communications link, which is provided by communication service provider.  A router is needed to route packets, delivered to the router by a switch, out of a network segment or LAN.  The communications link is used as a carrier of these data packets to the destined LAN.  The communication links used to connect two WAN points together are either a single point to point Leased Line connection or as part of shared entities packet-switching or circuit-switching.

 

However, an alternative to these cable based connections for LAN is Wifi, whilst an alternative for WAN cable technologies is Wimax.  Both are wireless based technologies.  Wireless LANs, particularly in home networks, are peer to peer.  Wireless switches and routers can be used to connect Wireless

 

Network speed

The network speed, the speed of which data packets are transported, is faster for a LAN than for a WAN.  A LAN’s maximum speed can reach up to ten gigabytes per second.  A one hundred gigabyte LAN is also in the making.  WAN spends depend on the type of WAN service being used but will never be as fast as Ethernet LANs because the sole aim of a WAN is to transfer data between one LAN to another. There is, therefore, not an urgent need for WANs to be extremely fast unlike communication requirements within a LAN.

 

The speed of a wireless LAN depends very much on the wireless LAN standard that is being used, same goes for Wireless WANs.  

 

Expansion

To add another workstation or printer to the LAN all that's needed is just a Network Interface Card.  The Ethernet cable is attached to the Network Interface Card to the port on a switch. The switch automatically picks up the address of the new workstation, therefore requiring no configuration

 

Extending a WAN to include another LAN can involve purchasing another router if present routers have no spare serial ports, with the ports requiring configuration and testing to recognise the new LAN connection.  An extra communications link also needs to be hired from the service provider. Additionally, extra investment into powerful receivers and transmitters is required if the new LAN connection is of a distance of hundreds of miles as such length can leave the connection susceptible to attenuation and noise.

 

Cost

Because of the simplicity of configuration and adding workstations to a LAN, and the hardware requirements are therefore much lower to set up a LAN, the cost of a LAN setup is much less than the cost of a WAN setup.  Routing, employed by WANs, is also more expensive than LAN switching. 

 

LANs and WANs are different technologies that are used for different purposes.  Therefore businesses need to perform in-depth network and data requirements as well as various cost analysis procedures to determine if they require a LAN or a WAN.  If a business has a single building, then a LAN would suffice.  If they have several premises across a country then it is likely that a WAN is required if they intend on transmitting data between different LANs.
