The page includes the following fields:

Object Description

Port

Indicate port 1 to port 24.

Edge

Indicates whether the port is enabled as an edge port.

Edge port cannot create loops, but it loses edge port status if a topology change

creates a potential for a loop. An edge port normally should not receive BPDU

packets. If a BPDU packet is received it automatically loses edge port status.

Path Cost

The port contribution to the root path cost. The path cost is adjusted to a higher or
