Syntax
vlan-mapping modulo modulo
Default
All VLANs are mapped to the CIST (MSTI 0).
Views
MST region view
Predefined user roles
network-admin
Parameters
modulo: Sets the modulo value in the range of 1 to 64.
Usage guidelines
You cannot map a VLAN to different MSTIs. If you map a VLAN that has been mapped to an MSTI to
a new MSTI, the old mapping is automatically removed.
This command maps each VLAN to the MSTI with ID (VLAN ID – 1) % modulo + 1. (VLAN ID – 1) %
modulo is the modulo operation for (VLAN ID – 1). If the modulo value is 15, then VLAN 1 is mapped
to MSTI 1, VLAN 2 to MSTI 2, …, VLAN 15 to MSTI 15, VLAN 16 to MSTI 16, and so on.
Examples
# Map VLANs to MSTIs as per modulo 8.
<Sysname> system-view
[Sysname] stp region-configuration
[Sysname-mst-region] vlan-mapping modulo 8
