OmniSwitch CLI Reference Guide

• Configure ports that will connect to a host (PC, workstation, server, etc.) as edge ports to avoid unnec-

essary topology changes when these ports go active. This will also prevent the flushing of learned 
MAC addresses on these ports if a topology change occurs as a result of another non-edge port going 
active. If an edge port receives a BPDU, it will operationally revert back to a no point to point connec-
tion type.
