2. Range of values:
For details about how to set <VLAN ID list> and the specifiable values, see
Specifiable values for parameters.
3. Note on using this parameter:
- All VLANs that do not belong to other MST instances participate in MST
instance ID0.
- To configure the same MST region, the MST instance ID and the VLAN ID set
by this parameter, as well as the values of the
name parameter and the
revision parameter, must match within the MST region.
Default behavior
All VLANs belong to MST instance ID0.
Impact on communication
When mst is set for the spanning-tree mode command, recalculation of the topology
interrupts communication until the topology is formed.
When the change is applied
The change is applied immediately after setting values are changed.
