Hi Netpro.

In general, trackback might indicate a software issue. But it might be cosmetic and won't impact the performace/operation. Can you post "show ver" here?

Hello Jack,

on a trunk port portchannel 1 an inconsistent BPDU is received with an external vlan tag different from the vlan field inside the BPDU itself (Cisco PVST+ BPDU format on trunks).

This event normally should only trigger the events of blocking the port for vlan 30 and later to unblock.

in your case instead we see a software error event:

Jan 19 03:07:53.777 CCT: %PM-3-INTERNALERROR: Port Manager Internal Software Error (vlanid >=0 && vlanid < PM_MAX_VLANS: ../switch/pm/pm_vlan.c: 584:

pm_vlan_get_vlan_data)

-Traceback= 280E24 2B52BC 2C1350 33A940 33DE60 30D97C 30E91C 1D2310 1CC7E0

as you can see a C procedure contained in file pm_vlan.c returned an illegal code and a traceback has been produced as a result of the SW error.

If this doesn't happen anymore you should be fine otherwise you should consider to perform an IOS upgrade in your switch.

As we can see the SW error hadn't blocked events cycle: the port has been put in STP blocking for vlan 30

When the offending BPDU stopped to be received (it was only one) the port has been put again in unblocking.

Hope to help
