xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch CLI Reference Guide
765
Parameters
<value 0-61440> - Specify the bridge priority value, which must be divisible by 4096. The default
value is 32768.
instance_id - Specify the identifier value, which is used to distinguish different STP instances.
<value 0-64> - Specify the identifier value, which is used to distinguish different STP
instances.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To configure the STP instance ID:
DGS-3420-28SC:admin#config stp priority 61440 instance_id 0
Command: config stp priority 61440 instance_id 0
Success.
DGS-3420-28SC:admin#
79-13 config stp
Description
This command is used to configure the bridge parameter global settings.
Format
config stp {maxage <value 6-40> | maxhops <value 6-40> | hellotime <value 1-2> |
forwarddelay <value 4-30> | txholdcount <value 1-10> | fbpdu [enable | disable] |
nni_bpdu_addr [dot1d | dot1ad]} (1)
Parameters
maxage - Specify to determine if a BPDU is valid.
<value 6-40> - Specify to determine if a BPDU is valid. The default value is 20.
maxhops - Specify to restrict the forwarded times of one BPDU.
<value 6-40>
- Specify to restrict the forwarded times of one BPDU. The default value is 20.
hellotime - Specify the time interval for sending Configuration BPDUs by the Root Bridge. This
parameter is for STP and RSTP version. MSTP version uses per-port hellotime parameter.
<value 1-2> - Specify the time interval for sending Configuration BPDUs by the Root Bridge.
This parameter is for STP and RSTP version. MSTP version uses per-port hellotime
parameter. The default value is 2 seconds.
forwarddelay - Specify the maximum delay time for one BPDU to be transmitted by a bridge and
received from another bridge.
<value 4-30>- Specify the maximum delay time for one BPDU to be transmitted by a bridge
and received from another bridge. The default value is 15.
txholdcount - Specify to restrict the numbers of BPDU transmitted in a time interval (per Hello
Time).
<value 1-10> - Specify 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.
