Configuring the Switch

3-124

• Oper Path Cost – The contribution of this port to the path cost of paths towards

the spanning tree root which include this port.

• Oper Link Type – The operational point-to-point status of the LAN segment

attached to this interface. This parameter is determined by manual configuration or

by auto-detection, as described for Admin Link Type in STA Port Configuration on

page 3-126.

• Oper Edge Port – This parameter is initialized to the setting for Admin Edge Port

in STA Port Configuration on page 3-126 (i.e., true or false), but will be set to false

if a BPDU is received, indicating that another bridge is attached to this port.

• Port Role – Roles are assigned according to whether the port is part of the active

topology connecting the bridge to the root bridge (i.e., root port), connecting a LAN

through the bridge to the root bridge (i.e., designated port), or is the MSTI regional

root (i.e., master port); or is an alternate or backup port that may provide

connectivity if other bridges, bridge ports, or LANs fail or are removed. The role is

set to disabled (i.e., disabled port) if a port has no role within the spanning tree.

• Trunk Member – Indicates if a port is a member of a trunk.

(STA Port Information only)

These additional parameters are only displayed for the CLI:

• Admin status – Shows if this interface is enabled.

• External path cost – The path cost for the IST. This parameter is used by the

STA to determine the best path between devices. Therefore, lower values should

be assigned to ports attached to faster media, and higher values assigned to ports

with slower media. (Path cost takes precedence over port priority.)

Alternate port receives more

useful BPDUs from another

bridge and is therefore not

selected as the designated

port.

R: Root Port

A: Alternate Port

D: Designated Port

B: Backup Port

ADB

Backup port receives more

useful BPDUs from the same

bridge and is therefore not

selected as the designated

port.
