Parameter
instance-id: Specifies the spanning tree instance ID, ranging from 0 to 16, instance 0 is
CIST.
vlan-list: Specifies the VLAN list and expressed as vlan-list = { vlan-id [ to
vlan-id ] }&<1-10>. VLAN ID ranges from 1 to 4094. &<1-10> means that the preceding
parameters can be entered up to 10 times. The switch may support VLAN 4095, 4096
others, however, they can only be mapped to CIST (Instance 0).
Description
Using instance command, you can map the specified VLAN list to the specified STI.
Using undo instance command, you can cancel the specified VLAN list from the
specified STI, the removed VLAN will then be mapped to the CIST (i.e., the Instance 0).
If no VLAN is specified in the undo command, all the VLANs associated with the
specified STI will be mapped to CIST.
By default, all the VLANs are mapped to CIST, i.e., the Instance 0.
MSTP describes the association between VLANs and STIs with the VLAN mapping
table. You can use this command to configure this table. Every VLAN can be mapped to
an STI as per your configuration.
A VLAN cannot be mapped to different instances at the same time. The latter
configured association will replace the former one.
For the related command, see region-name, revision-level, check
region-configuration , vlan-mapping modulo, active region-configuration .
