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 113 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.
mxage <6-40>	Configures the bridge maximum age. The maximum age parameter specifies the
	maximum time the bridge waits without receiving a configuration bridge protocol
	data unit before it reconfigures the STP network. The range is 6 to 40 seconds, and
	the default is 20 seconds.
	This command does not apply to MSTP. See the “Common Internal Spanning Tree
	configuration” section for more information.
