Distributed Spanning Tree Commands

spantree msti vlan

Defines an association between a range of VLANs and a single Multiple Spanning Tree Instance (MSTI).
The MSTI-to-VLAN mapping created with this command is one of three attributes (name, revision level,
and a VLAN to MST instance association table) that defines an MST region as required by the IEEE
802.1Q 2005 standard. Switches that share the same attribute values are all considered part of the same
MST region. Currently each switch can belong to one MST region at a time.
spantree msti msti_id vlan vlan_id[-vlan_id2]
no spantree msti msti_id vlan vlan_id[-vlan_id2]
Syntax Definitions
msti_id
vlan_id
[vlan_id2]
Defaults
By default, all VLANs are associated with the flat mode Common and Internal Spanning Tree (CIST)
instance, which is also known as MSTI 0.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
Use the no form of this command to remove a VLAN or a range of VLANs from the specified MSTI
association.
•
Note that the VLAN ID specified with this command does not have to already exist in the switch
configuration. This command maps VLAN IDs to MSTIs, but does not create VLANs.
•
A VLAN is associated with only one MSTI at a time, but it is possible to move a VLAN from one
MSTI to another. In addition, it is also possible to assign only one VLAN to an MSTI; a range of
VLANs is not required.
•
To associate multiple VLANS in a single command, use a hyphen to specify a range of VLAN IDs and
a space to separate multiple VLAN IDs and/or ranges (for example 100-115 122 135 200-210).
•
Configuring an MSTI-to-VLAN mapping is allowed when the switch is operating in either the per-
VLAN or flat Spanning Tree mode, as long as MSTP is the selected flat mode protocol. The MSTI
configuration, however, is not active unless the switch is running in the flat mode.
Examples
-> spantree msti 10 vlan 100-115
-> spantree msti 20 vlan 122
-> no spantree msti 10 vlan 100-115
