Port blocking STP

    Posted May 01, 2014 07:29 AM

    I have a customer who has just had a 7210 controller installed and we are having some connectivity issues to the controller. Every couple of hours the switchport which is an HP switch cycles through its STP port states. I have spanning-tree disabled on the controller and the issue is seen on the controllers 0/0/0 port which is configured as a trunk. The only other port connected is 0/0/1 which is an access port in a VLAN that does not cross the trunk - no issues seen on this port. I have downloaded the logs from the controller, so is there a file in there where I can see the port up/down events to see if this is triggering the HP port to run STP. I admit I do not know much about HP switches so if this sounds wrong please correct me.

     

    switch output -

    I 05/01/14 08:48:44 00076 ports: port C2 is now on-line
    I 05/01/14 08:47:54 00435 ports: port C2 is Blocked by STP
    I 05/01/14 08:32:36 00076 ports: port C2 is now on-line
    I 05/01/14 08:32:32 00435 ports: port C2 is Blocked by STP

    the network log on the controller would show you if there are any port up/down events.
