•
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
page 10-13.
•
Oper Edge Port
– This parameter is initialized to the setting for Admin Edge Port
in STA Port Configuration on page 10-13 (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)
Alternate port receives more
useful BPDUs from another
bridge and is therefore not
selected as the designated
port.
