DGS-3450:admin# config stp version mstp
Command: config stp version mstp
Configure value is the same with current value.
Fail!
DGS-3450:admin#
config stp priority
Purpose
Used to configure the instance priority.
Syntax
config stp priority <value 0-61440> instance_id <value 0-15>
Description
One of the parameters used to select the Root Bridge.
Parameters
priority
- The bridge priority value must be divisible by 4096.
instance_id
- Identifier to distinguish different STP instances.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To config stp instance_id:
DGS-3450:admin# config stp priority 61440 instance_id 0
Command: config stp priority 61440 instance_id 0
Success.
DGS-3450:admin#
config stp
Purpose
Used to configure the bridge management parameters for CIST (instance_id = 0).
Syntax
config stp {maxage <value 6-40> | maxhops <value 1-40> | hellotime <value 1-10> |
forwarddelay <value 4-30> | txholdcount <value 1-10> | fbpdu [enable(3)|disable(2)] |
lbd [enable(1)|disable(0)] | lbd_recover_timer [<value 0> | <value 60-1000000>] |
nni_bpdu_addr [dot1d | dot1ad]}(1)
Description
This command is used to configure the bridge parameters global settings.
Parameters
maxage
- Used to determine if a BPDU is valid. The default value is 20.
maxhops
- Used to restrict the forwarded times of one BPDU. The default value is 20.
forwarddelay
- The maximum delay time for one BPDU to be transmitted by a bridge and
received from another bridge. The default value is 15.
txholdcount
- Used to restrict the numbers of BPDU transmitted in a time interval (per Hello
Time).
fbpdu
- To decide if the Bridge will flood STP BPDU when STP functionality is disabled.
nni_bdpu_addr
- Used to determine the BPDU protocol address for STP in service provide
site. It can use 802.1d STP address, or 802.1ad service provider STP address.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To config stp:
