Bridge Identifier

The unique identifier associated with this bridge instance. It consists of the bridge
priority and the bridge’s base MAC address.

Bridge Max Age

The value that all bridges use for Max Age when this bridge is acting as the root: a
BPDU will be discarded when its age exceeds maxage.

Bridge Hello Time

The value that all bridges use for HelloTime when this bridge is acting as the root.
Hellotime determines how often a hello message is broadcast; it cannot be longer
than maxage but should be longer than forwarddelay.

Bridge Forward Delay

The value that all bridges use for Forward Delay when this bridge is acting as the
root. Forwarddelay is used by bridges to ensure that a new network topology has
stabilized before leaving the blocking state. Note that IEEE 802.1D specifies that
the range for this parameter is related to the value of STP Bridge Maximum Age.

Bridge Hold Time

Minimum time between transmission of Configuration Bridge Protocol Data Units
(BPDUs).

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.
