[Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] stp transmit-limit 5 vlan-mapping modulo Syntax View vlan-mapping modulo modulo MST region view Default level 2: System level Parameters modulo: Sets the modulo value, in the range of 1 to 32. Description Use vlan-mapping modulo to map VLANs in the MST region to MSTIs according to the specified modulo value, quickly creating a VLAN-to-instance mapping table. By default, all VLANs are mapped to the CIST (MSTI 0). 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 will be automatically removed. This command maps each VLAN to the MSTI whose ID is (VLAN ID - 1) %modulo + 1, where (VLAN ID - 1) %modulo is the modulo operation for (VLAN ID - 1). If the modulo value is 15, for example, then VLAN 1 will be mapped to MSTI 1, VLAN 2 to MSTI 2, VLAN 15 to MSTI 15, VLAN 16 to MSTI 1, and so on. Related commands: region-name, revision-level, display stp region-configuration, check region-configuration, and active region-configuration.
