output definitions
Vlan The VLAN ID associated with the VLAN Spanning Tree instance.
Configured through the vlan commands
Port The slot number for the module and the physical port number or a logi-
cal port. If the slot number is 0, then the port number refers to a link
aggregate logical port number (e.g., 0/31).
Oper St The port operational state as defined by application of the Spanning
Tree Protocol. Possible port operational states include: disabled, block-
ing, listening, learning, and forwarding.
Path Cost The contribution of this port to the path cost towards the Spanning Tree
root bridge that includes this port. Path cost is a measure of the distance
of the listed port from the root bridge in the number of hops. Config-
ured through the bridge 1x1 slot/port path cost command.
Desig Cost The path cost of the Designated Port of the segment connected to this
port. If this is the root bridge or the Spanning Tree status of the port is
administratively disabled, this value is 0.
Role The role of the port for this Spanning Tree instance. Possible port roles
are: root, designated, alternate, master, and backup.
Prim. Port The slot number for the module and the physical port number on that
module for the primary port associated with this Spanning Tree
instance. This information is only available if the port role is backup.
Op Cnx Operational connection type: PTP, NPT, or NS (nonsignificant).
Shows the current operational state of the port’s connection type. See
the bridge slot/port connection command on page 16-87 for more
information.
Op Edg Operational connection type: EDG. Shows the current operational state
of the port’s connection type. See the bridge slot/port connection
command on page 16-87 for more information.
