Mapping between VLANs and MSTIs
Revision level of the MST region
Run:
instance instance-id vlan { vlan-id [ to vlan-id ] }&<1-10>
The mapping between an MSTI and VLANs is set.
Run:
vlan-mapping modulo modulo
The default algorithm is used to set the mapping between MSTIs and VLANs.
NOTE
In the command, vlan-mapping modulo indicates that the formula (VLAN ID-1)%modulo+1 is used. In
the formula, (VLAN ID-1)%modulo means the remainder of (VLAN ID-1) divided by the value of
modulo. This formula is used to map a VLAN to the corresponding MSTI. The calculation result of the
formula is ID of the mapping MSTI.
