Displaying the STP Interface Configuration for a Specific
Interface
The
show spanning-tree interface
command, in Privileged (Enable) mode, displays the Spanning-
Tree topology for the specified port.
Table 7
describes the parameters displayed by this command.
Command Syntax
device-name
#
show spanning-tree interface UU/SS/PP
Example 1
The following example displays the STP interface parameters when the bridge is not the Root
Bridge:
device-name
#
show spanning-tree interface 1/1/1
PortPriority = 128
PortState = disabled
PortEnable = disabled
PortPathCost = 10
DesignatedRoot = 08192.00:12:F2:00:00:03
DesignatedCost = 19
DesignatedBridge = 32768.00:12:F2:11:29:82
DesignatedPort = 128.1
FrwrdTransitions = 0
TopChangeDetection = Enabled
Example 2
The following example displays the STP interface parameters when the bridge is the Root Bridge:
device-name
#
show spanning-tree interface 1/1/1
PortPriority = 128
PortState = disabled
PortEnable = disabled
PortPathCost = 10
DesignatedRoot = This bridge is the root
DesignatedCost = 0
DesignatedBridge = This bridge
DesignatedPort = 128.1
FrwrdTransitions = 0
TopChangeDetection = Enabled
Displaying the STP Configuration and Topology for All Ports
The
show spanning-tree
command, in Privileged (Enable) mode, displays the current STP
parameters settings and the spanning tree topology for all ports.
Table 6
and
Table 8
describe the
parameters displayed by the
show spanning-tree
command.
