rapid-spanning-tree interface
The
rapid-spanning-tree interface
command, in Protocol Configuration mode, changes the
mode to interface configuration mode. This mode enables you to set the RSTP interface
configuration. If the argument
all
is specified, this command displays the Rapid-Spanning-
Tree topology for all ports and does not change the configuration mode. See also Displaying
Port Rapid-Spanning-Tree Topology Settings
.
Command Syntax
device-name
(cfg protocol)#
rapid-spanning-tree interface
{
UU/SS/PP|
all
}
Argument Description
UU/SS/PP
Unit, slot and port number of interface to be configured. The configuration mode is
changed accordingly.
all
The configuration mode does not change. Rapid Spanning Tree topology for all ports is
displayed.
Examples
1. The following examples display the output of the RSTP interface
for an interface with link
enabled:
device-name
(cfg protocol)#
rapid-spanning-tree interface 1/1/1
PortPriority = 128
PortState = forwarding
PortRole = Designated Port
PortEnable = enabled
PortPathCost = 200000
DesignatedRoot = This bridge is the root
DesignatedCost = 0
DesignatedRoot = This bridge
DesignatedPort = 128.62
FrwrdTransitions = 1
Admin EdgePort = disabled
EdgePort = disabled
AdminLink-Type = Auto
Link-Type = P2P
MigrationTimer = 3
2. The following example displays the rapid-spanning-tree topology for all interfaces:
device-name
(cfg protocol)#rapid-spanning-tree interface all
