config stp
Description
This command is used to configure the bridge parameters 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]}
Parameters
maxage - (Optional) Used to determine if a BPDU is valid. The default value is 20.
●
<value 6-40> - Enter the maximum age value here. This value must be between 6-40.
●
maxhops - (Optional) Used to restrict the forwarded times of one BPDU. The default value is 20.
●
<value 6-40> - Enter the maximum hops value here. This value must be between 6 and 40.
●
hello_time - (Optional) The time interval for sending configuration BPDUs by the Root Bridge. The
●
default value is 2 seconds. This parameter is for STP and RSTP version. MSTP version uses per-port
hellotime parameter.
<value 1-2> - Enter the hello time value here. This value must be between 1 and 2.
●
forwarddelay - (Optional) The maximum delay time for one BPDU to be transmitted by a bridge
●
and received from another bridge. The default value is 15.
<value 4-30> - Enter the maximum delay time here. This value must be between 4 and 30.
●
txholdcount - (Optional) Used to restrict the numbers of BPDU transmitted in a time interval.
●
<value 1-10> - Enter the transmitted BPDU restriction value here. This value must be between 1
●
and 10.
fbpdu - (Optional) To decide if the bridge will flood STP BPDU when STP functionality is disabled.
●
enable - Specifies that the bridge will flood STP BPDU when STP functionality is disabled
●
disable - Specifies that the bridge will not flood STP BPDU when STP functionality is disabled
●
nni_bpdu_addr - (Optional) Used to determine the BPDU protocol address for GVRP in service
●
provide site. It can use 802.1d GVRP address, 802.1ad service provider GVRP address or an user
defined mutilcast address. The range of the user defined address is 0180C2000000 - 0180C2FFFFFF.
dot1d - Specifies that the NNI BPDU protocol address value will be set to Dot1d.
●
dot1ad - Specifies that the NNI BPDU protocol address value will be set to Dot1ad.
●
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
