instance

To map a VLAN or a set of VLANs to a single Multiple Spanning Tree (MST)

instance, use the instance command. To return the VLANs to the default

instance (CIST), use the no form of this command. Use the no form of this

command to remove and interface.

instance INSTANCE-ID vlans VLANDID [ , | . ]

no instance INSTANCE-ID [vlan VLANID [, | -] ]

Default No VLANs are mapped to any MST instance (all VLANs are mapped to the CIST

instance).

Command Mode MST configuration.

Usage Guideline Any unmapped VLAN is mapped to the CIST instance.

MSPT, ERPS, and LBD module share a Spanning-Tree Group (STG) table.

There is a formula to calculate the expected max STG number when a module

requests an STG entry. If the number is over the STG tables supported

maximum, the STG request will fail.

Below is the formula and example:

[EXPECTED_MAX_STG] mstp_instance_num*erps_instance_num +

mstp_instance_num + ctp_blocked_num

[Example]

MSTI 1 : V1-V8

MSTI 2 : V9-V16

ERPI 1 : V1, V9

ERPI 2 : V2, V10

CTP : V3

VLAN 4~8 : MSTI 1 (stg 1)

VLAN 11~16 : MSTI 2 (stg 2)

VLAN 1 : MSTI 1 -> ERPI 1 (stg 3)

Syntax Description

63.

vlans VLANDID [ , | .] Specifies the number of the VLANs to be mapped to the specified instance; valid

values are from 1 to 4094.
