4922593: Link Messages Seem to Contradict IPMP State During a Switch Reset
If you have IPMP configured on a blade and you reset the chassis’s integrated switch, you will see an error message that appears to contradict the IPMP configuration of the blade. The console output during the reset will possibly display several link up messages while the switch is physically in the process of resetting (see below). There will be no corresponding link down messages. This behavior is a result of the way the bge driver negotiates with the switches. It has no negative impact on network connectivity or on the operation of IPMP. When the switch reset completes, the link status will be correct and IPMP will be functioning correctly.
