Perform the following procedure if
you increase or decrease the number of links that connect the chassis to the
fabric interconnect. Acknowledging the chassis ensures that
Cisco UCS Manager is aware of the change in the number of links and that traffics
flows along all available links.
After you enable or disable a port on a fabric interconnect, wait for at
least 1 minute before you reacknowledge the chassis. If you reacknowledge the chassis too soon, the pinning of server traffic from the chassis may not be updated with the changes to the port that you enabled or disabled.
The following example acknowledges chassis 2 and commits the
UCS-A# acknowledge chassis 2
