ICX 6610 - MsgAgeExpiry after increasing "system-max spanning-tree"

After increasing "system-max spanning-tree" from default of 32 to 64 we have seen multiple vlans at the same time have the 802-1w MsgAgeExpiry trigger.  Prior to this change there were no events.

CPU looks fine, no errors/CRCs on links, etc.  I can only assume this change caused the issue.

Any ideas?

Hi Paulcian,

Increasing the spanning tree default values might not lead to MsgAgeExpiry logs. This is usually seen when a switch in a spanning tree domain notices a topology change indicating that a BPDU was not received by the port for the default max_age time.
