Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• This command defines the priority for the use of a port in the
Spanning Tree Algorithm. If the path cost for all ports on a switch are
the same, the port with the highest priority (that is, lowest value) will
be configured as an active link in the spanning tree.
• Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled.

Command Usage
• You can enable this option if an interface is attached to a LAN
segment that is at the end of a bridged LAN or to an end node. Since
end nodes cannot cause forwarding loops, they can pass directly
through to the spanning tree forwarding state. Specifying Edge Ports
provides quicker convergence for devices such as workstations or
servers, retains the current forwarding database to reduce the amount
