Known Affected Releases

6.2(1.5) 6.2(6)S12

Description (partial)

Not a scale, that customer would typically configure, and a workaround exists as well

Symptom:
On scale/batched triggers such as FEX reloads, peer reloads, etc, we see STP set port state failures.

Conditions:
Issue is specifically seen with a scale configuration of around 20 host interfaces or more with 75 VLANs per host interface on a 2248PQ FEX type.  With this configuration, when batched triggers are executed, STP set port failure are seen.
