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
