Spanning Tree Common Spanning Tree (Cst) Commands - Bull 1GB Intel Ethernet Switch Module Installation And User Manual

Spanning tree Common Spanning Tree (CST) commands

config spanningtree cst port edgeport
Use this command to specify whether a port is an edge port within the Common Spanning Tree
(CST). This will allow the port to transition to Forwarding State without delay. The <port> is the
port to be affected. The edgeport value can either be "true" or "false".
Default false
Format config spanningtree cst port edgeport <port> <true/false>
config spanningtree cst port pathcost
Use this command to configure the path cost to a new value for the specified port in the CST. The
<port> is the port to be affected. The pathcost value can be specified as a number in the range of 1 to
200000000 or auto. If <auto> is specified, the pathcost value will be set based on Link Speed.
Default auto
Format config spanningtree cst port pathcost <port> <1-200000000/auto>
config spanningtree cst port priority
Use this command to configure the port priority to a new value for use within the CST. The <port> is
the port to be affected. The priority value is a number in the range of 0 to 240 in increments of 16.
Default 128
Format config spanningtree cst port priority <port> <0-240>
show spanningtree cst detailed
Use this command to display STP settings for the CST.
Format show spanningtree cst detailed
Bridge Priority
The value of the first two octets of the eight octet Bridge ID. Valid values are 0 to
61440. Factory default is 32768.
Bridge Identifier
The unique identifier associated with this bridge instance.
Time Since Topology Change
The time (in seconds) since the last time a topology change was detected by the
bridge entity.
Topology Change Count
The total number of topology changes detected by this bridge since the management
entity was last reset or initialized.
Topology Change in progress
Boolean value of the topology change parameter for the switch indicating whether a
topology change is in progress on any port assigned to the CST.
Designated Root
The identifier of the bridge currently assumed to be the root of the spanning tree.
Root Path Cost
The cost of the path to the root as seen from this bridge.
Root Port Identifier
The port number of the port which offers the lowest cost path from this bridge to the
root bridge.
