5508 WLC to Nexus

hi sandeep,

we are not using any LAG in this case .

we are just connecting the WLCs from 6500 core1 & 2 to Nexus Core 1 & 2.

we are using AP manager interface in Hsrp in 6500 core1 & 2.

but we are not using any hsrp in Nexus.

this is the chalange now.

Hi Venkata,

Right now I dont have any cisco documention for specific connection, if i will get it then let you know.

One more thing: Cisco 5500 Series Controllers, you are not required to configure an AP-manager interface. The management interface acts like an AP-manager interface by default, and the access points can join on this interface.

If you face any problem while configuration then just posts your error description then only we can try to solve ur problem.

Also check this link, may be it helps:

Re: 5508 WLC to Nexus

Venkata,

When we have migrated WLC's off of 6500's (non VSS) to a Nexus, we would only connect on WLC to one of the Nexus. What I mean here is that, you mentioned WLCs, so I'm guessing you have more than one. I wouldn't split the AP managers with how you have the new setup. Since you have two WLC's and two Nexus cores, you should configure LAG on the WLC and use the management interface as the ap manager also and define one WLC to one if your Nexus and the other WLC connect to the other Nexus core. You should have enough redundancy on the WLC to support a failover in case one of your cores goes down. The thing to understand about AP managers is that on the 4400's for example, these were desperate from the management. The 5508's or the newer WLC's traffic flow differs and that is why by default the ap manager is defined on the management interface. The AP needs to communicate to both the managemt and ap manager, where in the past, it only needs to connect to the ap manager. So the initial connection the AP uses is to the manager and then when that connection happens, the ap will use the ap manager. So if the AP's loose connectivity to the management interface, they will move to a secondary WLC. The management interface on these newer WLC is important.

Re: 5508 WLC to Nexus

You can connect it to a Nexus, but if your planning on using LAG on the WLC, you need to be in the newer code on the Nexus that supports src-IP-dst load balancing which the WLC uses.

Re: 5508 WLC to Nexus

Hi

This thread may be useful to read as it describe certain DHCP related bug which could impact your WLC environment. So go for a bug fixed NX-OS code if you are going ahead with it

https://supportforums.cisco.com/thread/2231511

Addendum - we ran into the same problem with Wireless APs going via a Nexus 5k L3 core. Upgrading to a fixed NX-OS release resolved the issue.
