Cisco 1131 APs in HREAP mode producing output drops on interface of Switch

[Brian Millard]

We have a 5508 controller on the latest code 7.0.98.0 and several Cisco 1131 access points.

Each of the access points are connected to a Cisco switch whether its a 2960 or 2975.

We are experiencing output drops from the interface that they are connected.

The config of the interface on the switch is very simple "switchport mode trunk"

We also have several Cisco 1252s that are on the same controller but are not having the same issue.

Any ideas?

did we try using some other switchport connecting 1131??

Yes, we have tried multiple ports on the switch.  We have about 15 Cisco 1131 access points all are giving the same output drops.

We have all of our APs in HREAP mode so that if the controller goes down we don't lose wireless clients.

We have several 1242 and 1252 Cisco APs that are not having this issue.

Thanks

did we try connecting the AP to the port on which the 1242 Aps are connected?? are we still observing the same??

Yes, we have brought 3 types of access points into the computer room to observe the issue the 1131, 1242 and the 1252 and the only one that produces the output drops is the 1131.

We do have dynamic interfaces on the controller that correspond to the VLANs that the HREAP APs are in, I am not sure if this would be a problem or not.

hmm.. nope that wont cause anything.. VLAN mappings done correctly for the remote vlan and also for the WLANs??

Yes, our controller is on vlan 1 and the AP is native to vlan 417

Here are some images.
