Command	Description

brg	Displays the Bridge Spanning Tree Menu.

port <port number>	Displays the Spanning Tree Port Menu.

add <1-4095>	Associates a VLAN with a spanning tree and requires an external VLAN ID as a
	parameter.

remove <1-4095>	Breaks the association between a VLAN and a spanning tree and requires an
	external VLAN ID as a parameter.

clear	Removes all VLANs from a spanning tree.

on	Globally enables Spanning Tree Protocol.

default	Restores a spanning tree instance to its default configuration.

cur	Displays current Spanning Tree Protocol parameters.

Bridge Spanning Tree configuration

Command: /cfg/l2/stp/brg

[Bridge Spanning Tree Menu]
prior	- Set bridge Priority [0-65535]
hello	- Set bridge Hello Time [1-10 secs]
mxage	- Set bridge Max Age (6-40 secs)
fwd	- Set bridge Forward Delay (4-30	secs)
cur	- Display current bridge parameters

Spanning tree bridge parameters can be configured for each Spanning Tree Group. STP bridge parameters include:

•Bridge priority

•Bridge hello time

•Bridge maximum age

•Forwarding delay

•Current bridge configuration

The following table describes the Bridge Spanning Tree Configuration Menu options.

Table 111 Bridge Spanning Tree Configuration Menu options

Command	Description

prior <0-65535>	Configures the bridge priority. The bridge priority parameter controls which bridge on the
	network is the STP root bridge.
	To make this switch the root bridge, configure the bridge priority lower than all other switches
	and bridges on your network. The lower the value, the higher the bridge priority. The range is 0
	to 65535, and the default is 32768.
	RSTP/MSTP: The range is 0 to 61440, in steps of 4096 (0, 4096, 8192...), and the default is
	32768.
	This command does not apply to MSTP. See the “Common Internal Spanning Tree configuration”
	section for more information.

hello <1-10>	Configures the bridge hello time. The hello time specifies how often the root bridge transmits a
	configuration bridge protocol data unit (BPDU).
	Any bridge that is not the root bridge uses the root bridge hello value. The range is 1 to 10
	seconds, and the default is 2 seconds.
	This command does not apply to MSTP. See the “Common Internal Spanning Tree configuration”
	section for more information.
