Bridge Msti Vlan - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

Distributed Spanning Tree Commands

bridge 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.
bridge msti msti_id vlan vid_range
bridge msti msti_id no vlan vid_range
Syntax Definitions
msti_id
vid_range
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 6400, 6850, 6850E, 6855, 9000E
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.
•
Configuring an MSTI-to-VLAN mapping is allowed when the switch is operating in either the 1x1 or
flat Spanning Tree mode, as long as MSTP is the selected flat mode protocol. However, the MSTI
configuration is not active unless the switch is running in the flat mode.
Examples
-> bridge msti 10 vlan 100-115
-> bridge msti 20 vlan 122 135 200-210
-> bridge msti 10 no vlan 112 200-204
OmniSwitch CLI Reference Guide
An existing MSTI ID number (0–4094).
A VLAN ID number (1–4094) 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).
