Cisco Wireless :: 2504 Controller Association Latency

May 21, 2013

-WLC 2504
-AP1602
-SW  7.4.100.0
 
We have 22 x AP1602.5 of them show up in the WLC with Controller Association Latency of around 1 minute and 10 seconds.The other 17 all have latency around 10 seconds.
 
1. What are possibile causes for high value of association latency?

2. Could high-value association latency be an indication of badly working wifi for data traffic?

Cisco Wireless :: 2504 - Facing Latency For Wireless Users?

Oct 28, 2012

We have Wireless Setup and facing the latency issue for Wireless users , Wireless Controller is 2504 and AP are of  3600 Series .Even we stand below the AP , latency is in range of 19 to 20 ms , while client has Autonomous setup , so when he shifts the connectivity to Autonomous Setup he get latency is range 2 to 8 ms which is good then WLC setup...
 
While Testing We made the Single AP on which is integrated with WLC and check the Latency , but in these senario also it range from 19 to 20 ms ... ( Also sametime all Autonomous AP's were  Off  )
 
I am attaching the show techsupport to resolve the issue and tell me what fine tunning can be done to resolve the latency issue.

Cisco Wireless :: Adding A Second 2504 AP Controller

Aug 2, 2012

I currently have a single 2504 Controller managing 50 AP's.  I am adding a Second 2504 AP Controller with 15 Lic to manage an additional 10 AP's.  My current 2504 has each port configured for my four subnets that and it is managing AP's in 4 buildings.  Should I configure the new 2504 the same way so that it can see all four sites?  All so if the main 2504 goes down can the second 2504 take over even thou we will be out of lic?

Cisco Wireless :: 2504 Controller - Can AP Be Set With Static Channels

Nov 11, 2012

We have a Cisco 2504 controller and approximately 35 AP's. Some of the AP's are located directly above each other (on another floor). When I run a basic annalyzer, it appears that there is some adjacent AP traffic, the controller has some of the close AP's with the same channel, so there is some RF interferance. The AP's currently are all setup for "G" and majority of the AP's are 1200 series, most of them are 1242's. Should and can the AP's be set with static channels so that there is no adjacent signals? If so where in the controller can that be done?

Cisco Wireless :: 3602 AP Cannot Join 2504 Controller

Oct 16, 2012

This is a new setup and has not worked yet. I have multiple 3602 APs and one 2504 Controller. I thought initially I could plug-in an AP into one of two POE Ports on the 2504. During debug mode I see that it has low power, was suprised that the 2504 switch can't fully power the AP? Is this correct?Anyways I have another POE switch that I am using with ample power. The configuration for my wireless is that it will be completely segmented off of my internal network as this is for guest access. So DNS servers are external so I cannot create host entries for the AP to discover the controller. With that being said I believe that is just one way for the discovery process to happen. I have my controller management interface and DHCP scope on the controller on the same subnet plugged into the same POE switch. The AP does seem to get a DHCP address and I can ping the controller from the AP. I cannot get any further then that. I will not join the controller and the radios get disabled. I get messages such as "discovery response from MWAR is rejected. I will post a debug log of the AP and its bootup process. This is new equipment so I would assume the firmware is somewhat up-to-date and the 3602 AP is somewhat the latest model.

Cisco Wireless :: 2504 Controller - Best Way To Have Internet Only Wi-Fi Network

Nov 29, 2012

Our current way of configuration for this is standalone ap's with multiple ssid's. The main network ssid's are on the 10.0.0.0 networks. The internet only ssid is on the 192.168.1.0 network. ( this is a wireless network only,no wired) They all get there dhcp address from a layer 3 switch. To prevent the wireless 192.168.1.0 intenet only network from getting to the 10.0.0.0 networks, we just put a simple source & destination deny acl on the in vlan interface of the 192.168.1.0 network on the layer 3 switch.Now that we are impementing a Cisco 2504 controller, the management and ap manger are both on the 10.0.0.0 network.( both on port 1 with dynamic ap manager enabled)  I can setup as many ssid's on the 10.0.0.0 network and they all work fine. But when I setup the 192.168.1.0 internet only ssid it will not connect. I'm assuming that its because the 192.168.1.0 network or anyone trying to connect and use that network has to go through the controller located on the 10.0.0.0 network. I'm thinking that the acl on the vlan interafce is the problem.So, if I'm correct, what is the best way to setup a separate internet only network through the private networks?

C2 and C3 are in the same mobility group than C1 (and all is up up in mobilty managment). When "DHCP Addr. Assignment" is enable on C1 : Clients on C2 received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C2 and all is working fine. Clients on C3 don't received their IP address by our external DHCP server via C1 and the guest tunneling betwenn C1 and C3, so nothing work.

Cisco Wireless :: Setting Up Aironet 2600 APs With 2504 Controller

Mar 19, 2013

I've recently purchased a 2504 Wireless controller, and I have 10 2600 APs to deploy.  I think I've set up the wireless controller OK - there doesn't seem to be much that needs to be done!  But I just can't seem to register an AP onto the system.

Just to briefly outline what I have done, I have connected to the Wireless Controller via terminal emulator and run through the setup, then I have connected OK to the web interface, and I am able to view and amend the controller's configuration.  So I have setup a WLAN and thats about it.

Next up I have powered on one of my 2600 APs, and I am able to view it working via terminal emulator again.  But I am seeing it continually running the same routine to connect to a controller, and all the time it just fails.  Below is what I am seeing.
 
One thing that I am unsure about is that I am unable to connect to the AP config pages via web browser, using the IP 192.168.0.97 (although it does ping okay).  Is that odd?
 
And the main question - why doesn't the AP connect to the wireless controller?  Do the APs need to be authroized on the controller first?  If I check the controller's web interface, under Monitor - Statistics - AP Join, I can see the AP listed with Status "Not Joined" but I don't know what I need to do to make it join!

Cisco :: 2504 Wireless Controller / Regular Packets Drops

I have deployed a cisco 2504 wireless controller along with four (04) lightweight access points (1041N) in four floors respectivly. The clients connect to the AP which is deployed in the lowest floor have regular timeouts/packet drops. Further this particular ap operates at channel 11 and it has around 11-13 rough access points in the same area and operates in channels such as 1,3,6,9,11. The DCA (dynamic channel allocation) is set to auto in the WLC. Further each ap has maximum of 07 -10 clients at any given time and I have changed this particular ap and checked still the result is same hence there is nothing wrong with the ap.

Cisco Wireless :: 2504 Originating More Than 1 EoIP Tunnel To An Anchor Controller

Feb 26, 2013

I'm attempting to set up (for testing purposes) a 2nd 'guest' SSID on an internal WLC (WLC-A), and terminate it in a DMZ on an anchor controller (WLC-B).  We already have a guest SSID originating on WLC-A and terminating on WLC-B though.  Is it possible to originate a 2nd guest SSID on WLC-A?
 
WLC-A - 2504 (7.2.x)
WLC-B - 5508 (7.2.x)
 
The problem I'm seeing is I'm getting no DHCP address assigned on the test SSID.  If I statically assign IP information I still have no connectivity.  It's as if the EoIP tunnel for the 2nd test SSID isn't functional.
