We are running a 4507R SupII+ switch with WS-X4548-GB host modules. After a host reloads and comes back online, the switchport dies. Attempting to shut/no shut the port, the following message is logged:
Aug 15 15:32:14.164 UTC: %C4K_SWITCHMANAGER-4-S2WERRORREPORT: PimEthAutoNeg: S2w Read/Write Error for port Gi4/25.
This happens on all switchports within this module only. The only way to recover the port is to disable inline power with the power inline never command. I have searched for a bug in this version 12.2(25)EWA4 relating to this and have found nothing.
Should I be suspecting a switch module failure?
