Unknown protocol drops with AP2700

bquesnel1 — Mon, 05 Jul 2021 09:45:28 GMT

We've been deploying some AP 2700 within our offices and been observing some "unknown protocol drops" on the switchports where the AP's are connected.

The AP's are associated to a 7500 wireless controller, running 8.0.100.0 code. The AP's are in lightwight configuration with flexconnect configuration (4 vlans/SSID) associated.

On the switch port, the port has the following configuration :

description Cisco AP
switchport mode trunk
load-interval 30
spanning-tree portfast

I also specified the allowed vlans, based on the vlans that were mapped on the Flexconnect group and I still get some unknown protocol drops on the AP ports.

Does anybody know what this could relate to ?

See whether those are related to jumbo frames ?

Rasika,

Thanks for the answer, but the jumbo frame issue seems to be specific to a version of code, which I am not running..... I'm running 8.0.100.0 code so not sure if I am affected by the bug for jumbo frame .
