Configuring the Switch
• Designated Port – The port priority and number of the port on the designated
bridging device through which this switch must communicate with the root of the
Spanning Tree.
• 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
3-154.
• Oper Edge Port – This parameter is initialized to the setting for Admin Edge Port
in STA Port Configuration on 3-154 (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 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.
