OmniSwitch CLI Reference Guide March 2011 page 5-13
spantree msti
Defines a Multiple Spanning Tree Instance (MSTI) number. This number identifies an association
between a range of VLANs and a single Spanning Tree instance. In addition, it is possible to assign an
optional name to the MSTI for further identification.
spantree msti msti_id [name name]
no spantree msti msti_id [name]
Syntax Definitions
msti_id A numeric MSTI ID number. A range of VLANs is
associated to an MSTI ID number.
name An alphanumeric string. Use quotes around string if the name contains
multiple words with spaces between them (for example “Alcatel-Lucent
Marketing”).
Defaults
By default, a flat mode Common and Internal Spanning Tree (CIST) instance always exists. The MSTI ID
number for this instance is 0.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
Use the no form of this command to remove the MSTI from the switch configuration.
•
Use the no form of this command along with the name parameter to remove the optional MSTI name
from the specified instance. The instance itself is not removed; only the name.
•
There is always one CIST per switch. Initially all VLANs are associated with the CIST instance.
•
Creating an MSTI 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.
