APAR status

  • Closed as program error.

Error description

  • In IEEE802.3ad mode, force failover from backup to
    primary
    channel does not work and hence backup will remain active
    channel forever until etherchannel is
    rebuild(rmdev/mkdev).
    This behavior will lead to total etherchannel
    failure when backup goes down while primary link is up.
    

Local fix

  • Rebuild etherchannel with rmdev/mkdev.
    

Problem summary

  • In IEEE802.3ad mode, force failover from backup to primary
    channel may not work and hence backup will remain active
    until etherchannel is rebuild(rmdev/mkdev).
    This behavior will lead to total etherchannel
    failure when backup goes down while primary link is up.
    

Problem conclusion

  • Etherchannel driver code is fixed to allow force failover from
    backup to primary.
    

Temporary fix
