Re: Spanning Tree

Hello,

here is what the Cisco Error Message Decoder says:

1. %SPANTREE-2-BPDU_SKEWING: BPDU skewed with a delay of [dec] seconds (max_age/2)

This message indicates that a BPDU for one or more VLANs or instances when MISTP is running has been skewed for a time longer than max_age/2. [dec] is the number of seconds.

Recommended Action: No action is required. To determine which VLAN has been skewed, use the show spantree bpdu-skewing command.

Recommended documents:
