Note
Do not disable a port that is part of a load-sharing group. Disabling
the port prevents it from forwarding traffic, but still allows the link to
initialize. As a result, a partner switch does receive a valid indication
that the port is not in a forwarding state, and the partner switch will
continue to forward packets.
Verifying the
Load Sharing
Configuration
The screen output resulting from the show ports
configuration command indicates the ports are involved in load
sharing and the master logical port identity.
