Cisco Wireless :: WLC5508 How Does A Typical Client Endpoint Select 802.11n Over 802.11a

May 13, 2012

In an enviroment with WCS and a WLC5508 with 40 AP's (WAPs are either 1262's and 1252's), I have noticed that the bulk of users are infact operating on 802.11g although most operating notebooks are running 802.11n capable NICs (including my own laptops NIC - but yet when I connect I connect at 54Mbps.). Only a small portion of registered clients are using 802.11n. All my WAPs have both radios enabled?My question is how does a client notebook select a "prefered" band of 802.11n. I know in some cases the wireless NICs themselves have an option to select the "Prefered Band", but there are many notebooks out there that dont have this option. What would make a client connect at 802.11n over 802.11g? Who makes that call ?

Cisco Wireless :: WLC5508 Client Can't Get Its IP

Feb 6, 2013

I'm using WLC5508 /w 7.0..My client do not get its IP. Status shown "DHCP_REQD".I found in (Cisco Live) Troubleshooting Wireless LANs with Centralized Controllers  This related with Enable/Disable DHCP Proxy checkbox. I solved. with Enabling this.But,
1) Why this box have been working correctly for longtime? No one did diable/enable this feature on my box.

2) I guest, ver7.0 Disables this chechbox by default. Or not? I also have others two 7.2 boxes. Those are all Enabled.

Cisco :: 5508 VLAN Select - DHCP Leases On Each Scope For Same Client

Sep 11, 2011

The 5508 is running code  I have created a group interface for 3 subnets and assigned the group to the WLAN.  Clients are getting IP addresses in a round robin fashion.  The issue or downside to this is if the lease has not expired before the next time the station connects to the WLAN it consumes an address on another subnet instead of grabbing the unexpired lease IP address on it's previous VLAN.  It seems that the WLC determines the VLAN in the interface group before the DHCP request from the client in case the client already received a DHCP address that has not expired.  This can be problematic since we have seen some iPhones requesting an address every 20 minutes thus consuming an address on every subnet in the interface group.  Other than setting a lease time extremely low what can be done to address this?

Cisco WAN :: 3845 - Typical Cause Of High Number Of Ifdiscards?

Jan 6, 2013

I am seeing a high number of  discards reported on one of my monitored WAn rtr (3845). Solarwinds Orion  NPM is reporting a steady flow of error on two links, but not all links. What is the typical cause of these reported discards? I see no  error or counter increases in the >sh int xx; where xx is the  interface shown in the solarwinds reports Google tells me that "An  interface discard is simply where the device has decided to discard a  packet for some reason. The reason a device discards the packet(s) is  typically hard to tell. It could be a corrupt packet, that the device is  busy, buffer overflows, packet size issues, and several other things."
The Orion Network Performance Monitor pulls the discard information  reported within Orion in the RFC1213:IfTable, more specifically  IfInDiscards and IfOutDiscards. These are the OIDs for IfInDiscards and IfOutDiscards we use to gather this
Interface Errors and Discards:
  OID = ifInDiscards
  OID = ifInErrors
  OID = ifOutDiscards

there are no error and only the outgoing direction has discards? How do i debug this more or get more info on how to track down the root cause?

Cisco Wireless :: 6509 - Apply MAC Filters On Select LAPs

Apr 29, 2012

We have a mix of 1231 and 1242 access points in an LWAPP environment. They are connected to WiSM controllers in our 6509's and are managed by a central WLC. Everything is running version 7.0.230. My question is can I apply MAC address filtering on a select group of AP's to restrict access to a specific SSID broadcast on these AP's without affecting other AP's also connected to the same WiSM?

Linksys Wireless Router :: Can't Select 802.11n Anymore On Wrt54g2

Jan 4, 2012

A couple of days ago I noticed my download speed (from my own webserver) has slowed down. I checked my wireless connection and saw that the radiotype was now 802.11g instead of 802.11n, what is always has been. I looked at the Wireless configuration in the router's webbased config panel, but the only things listed there are "Disabled", "Mixed", "Wireless-G Only" and "Wireless-B Only". A scratched my head a bit, wondering wether or not I really bought an N router or just a G router. But IIRC I really bought an N router. It said so on the bill. Also, when I check the user manual, page 14 says I should be able to select "Wireless-N Only".

Cisco Wireless :: Bonjour Gateway Deployment Need Vlan Select 6509E

Apr 9, 2013

Q: If i m going to do a Bonjour Gateway deployment, do i still need the vlan select feature on the wism's or is enabling multicast enough?
Details of the Q:
I m working with WISM s and WISM2;s, 1130 and 3602 ap;s. Cores are 6509-E's.
i m going to implement a Bonjour gateway (which is an Aerohive ap, no wifi enabled, its just a Bonjour gateway)
This ap is connected with a trunk port (to a 6509-E) and has the wifi client vlans on the trunk as allowed vlans. It also has an allowed vlan for AppleTV;s which will be wired devices.
The Aerohive gateway gets an ip address in every wifi subnet, so far so good.
I was thinking that if i enable multicast :
- globally on the wisms, with mcast-mcast distribution
- on the SVI's for the wifi client vlans
- on te SVI's of the vlans for cisco aps
- on the SVI for AppleTV
- SVI for wism management
- SVI for the Bonjour gateway
then do i still need vlan select? Maybe a stupid question, but i m not sure how to interpret some things in this document.

Linksys Wireless Adapters :: How To Select Operating Channel On AE3000

Jul 18, 2012

I have an AE3000 dual band wireless adapter using the Win 7 Pro OS.  At work our routers all use the same SSID, but utilize different channels.  In terms of signal strength, the strongest signal is usually, but not always, one of the channels on the 2.4GHZ band (usually 11).  However, in terms of speed of connection and lack of overcrowding, the best signal is invariably one the channels on the 5GHZ band (usually 161).  My AE3000 will inevitably connect to the strongest signal (channel 11) even though it only slightly stronger than the signal on channel 161 and furnishes a much slower connection than that obtainable on channel 161.  Is there any way I can "force" the AE3000 to connect via channel 161 rather than channel 11?

Linksys Wireless Adapters :: How To Select 5GHz Band For AE1000

Mar 4, 2011

The product literature for the AE1000 says that you can select which band to use. However there doesn't seem to be an option to do that. I have an E4200 and when I set it up, it assigned my 5GHz and 2.4GHz bands the same SSID. If I configure the AE1000 to connect to that SSID, it seems to connect to the 2.4GHz band. Do I have to change the SSID for 5GHz and initiate a connection to it manually?

Cisco Wireless :: WLC5508 - Backup WLC Across A WAN?

Jan 29, 2013

Currently we have 20 remote sites, each with 2-5 AP's each. They all connect back to our Main Data Site in the US and register on a single WLC5508.

We do not have a backup WLC, but are looking to purchase one. What I would like to know is, are there any problems with the secondary WLC being installed in our Main Data Site in Europe? These two main sites are connected via a 10M MPLS WAN.
So all the remote sites could still connect to the WLC in the US, but in the event of a WLC failure in the US, they would need to fail over to the site in Europe

looking at doing the site survey before detailed implementation. we plan to use a wlc5508, AP3602, a good tripod/stand, PoE switch and AirMagnet to conduct the site survey. i'm inclined to use a single AP and just a guest SSID and let AirMagnet merge the readings on where i 'locate' the AP (on 1 VLAN)

Cisco Wireless :: Several Remote Sites And Centralized WLC5508

Nov 8, 2011

I have been asked to setup wireless and we have purchased WLC 5508 and 1142 APs.We have several remote sites and a  centralized WLC.  The requirement are to have a common SSID  (Corporate) advertised across all the remote sites and have that SSID locally switched, and have another two SSID Guest and Mobile tunneled back to the central site (WLC).I want all the wireless (Corporate) clients to use the same subnet as the wired clients at each remote site, the IP assigment will be done by a DHCP server at the central site. The Guest and Mobile users will use a common subnet each across all the site and this will also be handled by the DHCP server at the central site.
I have enabled H-REAP with Centralized  Authentication and Local switching but I'm not sure about the second  part which is to have a common SSID (Corporate) across the remote sites and localy switched whilst having the other two SSIDs tunneled back to the WLC. Cisco TAC told me to configure dynamic interfaces for each of the remote site but then he said I still wouldn't be able to switch the Corporate traffic localy if I use a different subnet to the wired subnet for the wireless clients.

If that might be the cause, is it possible to get WLC to 100 Mbps?

Cisco Wireless :: Minimal WLC5508 CLI Configuration To Access GUI?

Sep 8, 2010

I have on my desk a WLC-5508 that I need to setup to ship to a remote location. Normally we configure 4402 model and this model/version appears to be much different. I am trying to configure just enough via the command line to access the GUI via a laptop directly connected to the device. I’ve gone through the Wizard Configuration Tool where you set the hostname, admin account, and management interface (among other things). We use LAG and tagged VLAN on the management interface. I’ve been told in the past this is how we configured the 4402 models via laptop directly connected once the GUI is accessible, but with LAG enabled I don’t understand how a laptop could communicate via trunk, so I've disabled LAG and set the VLAN to untagged. In either case the laptop does not communicate with the WLC. Skipping ahead to my current setup I see the following information via the CLI:

(Cisco Controller) show>interface detailed management
Interface Name................................... managementMAC Address...................................... IP Address....................................... Netmask.......................................
