vlan-mapping modulo
Syntax
vlan-mapping modulo modulo
View
MST region view
Parameters
modulo: Modulo by which VLANs are mapped to MSTIs, in the range of 1 to 16.
Description
Use the vlan-mapping modulo command to set the modulo by which VLANs are mapped to MSTIs.
By default, all VLANs in a network are mapped to the CIST (MSTI 0).
MSTP uses a VLAN-to-instance mapping table to describe VLAN-to-instance mappings. You can use
this command to establish the VLAN-to-instance mapping table and map VLANs to MSTIs in a specific
way.
Note that a VLAN cannot be mapped to multiple different MSTIs at the same time. A VLAN-to-instance
mapping becomes invalid when you map the VLAN to another MSTI.
