•
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 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 3-153.
•
Oper Edge Port
– This parameter is initialized to the setting for
Admin Edge Port in STA Port Configuration on page 3-153 (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.
Alternate port receives more
useful BPDUs from another
bridge and is therefore not
selected as the designated
port.
