  • 1.  S3500 port shutdown

    Posted Jul 09, 2014 08:55 AM

    Hello,

     

    We have a MAS s3500 in a stack running 7.2.0.0 that shows two ports being shutdown because of BPDU Guard, there is no longer anything connected in those two ports how would I proceed to clear those errors?

     

    Thanks

    Usually a shutdown / no shutdown will bring the port back up.

    Doesn't seem to be working in my case...

    Switch reboot?? :)

    Opening a TAC case will definitely get more eyes on this.

    Use this CLI:

    clear port-error-recovery

     

     

    (ArubaS1500-24P) #show interface gigabitethernet 0/0/22 | include shutdown
    Port shutdown reason : BPDU received

    (ArubaS1500-24P) #show port-error-recovery
