Aruba AP135 connected port has errors

We have deployed Aruba AP135 on a light weight mode with controller 7220US,


We are observing  "input errors" on AP connected port


We have connected the AP to Cisco Modular Switches with WS-X4548-GB-RJ45V  module

All accesspoint were recently deployed with new cabiling .


Same localtion we have teminated AP on a non POE moudle and it works with no errors

I have manually turned off the power inline to access points connected ports , (Power inline Admin state is now OFF and operational status off) still we are getting errors

Re: Aruba AP135 connected port has errors

This article was helpful thanks


i have some queries


we have set MTU 1500 on all our switches , how frequently MTU Discovery packets are sent ,


We understand that once the MTU with 1578 fails it drops it to 1500 does the AP again sends the MTU Discovery Pkt to 1578 ?


I got 7000 input errors recorded in last 5 days on AP connected port
