    Hi

    Have an issue where each of the core switches in the network are continually reporting this error in the logs:

    I think this is related to IP Router Discovery part of NAC IP resolution.

    NAC will connect to the default gateway to try to resolve the IP of the end system, and i think it will use port 161 not 162 , 162 is the port used for SNMP trap.

    Hi Ahmed,

    Thanks for posting.... think you might be spot on there!

    Should have captured on 161 and I might have seen and understood the request from NAC :)

    Checked the setting and was set too --Use Switch SNMP Credentials--, so changed it to match the actual credentials I use for the switches, and as of yet not see this message popup in the logs.



    Nice one, thanks for the help :)
