I have a 4400 LAN controller where the ap-manager port is on the same subnet and VLAN as the management port but I cannot ping the ap-manager IP nor will the LWAP associate to it. What could be my problem?
As it has already been stated, the ap-manager is not pingable. This interface is used as the source for the LWAPP tunnel so all packets going in and out should be LWAPP encapsulated.
If you just want to verify that it is alive and that there isn't a dup-IP you can ping it from the VLAN's default gateway and check the arp cache. If the mac-address is one of the controller's you are fine, if not there is another device on the network that also has this address assigned.
We have the similar problem at our end. In our setup, for load balancing purposes, we are using both AP manager in active state. Some APs are associating with AP Manager1 while some are getting associated with AP Manager2. We also confirmed that setting is working perfectly fine. However, very interestingly in the arp cache of default router, we can only see the AP Manager1 ip address and its respective mac-address. We don't find the AP Manager2 ip and its mac-address. And ofcourse, these ip addresses are not pingable from default router (as stated in the discussion). We are running the code 184.108.40.206 on WLC 4402.
Can you please assist us in this regard, its much appreciated.
Singel AP-Manager interface works but there are some limitation given below:
With single AP-manager interface, on 4402, only 48 APs can be associated. For 50 APs you need to use second AP-Manager interface. We also want to achieve load balancing, using both AP-manager interfaces.
As mentioned above, two AP-manager interfaces works as well. Some APs are associated with AP-Manager1 while some are associated with second interface AP-Manager2. However we are not able to see the mac-address / ip address of AP-Manager interfaces on default gateway.
