bridge auto-vlan-containment
Enables or disables Auto VLAN Containment (AVC). When enabled, AVC prevents a port that has no
VLANs mapped to an Multiple Spanning Tree Instance (MSTI) from becoming the root port for that
instance. Such ports are automatically assigned an infinite path cost value to make them an inferior choice
for root port.
bridge [msti msti_id] auto-vlan-containment {enable | disable}
Syntax Definitions
msti_id
An existing MSTI ID number (0–4094).
enable
Enables automatic VLAN containment.
disable
Disables automatic VLAN containment.
Defaults
By default, automatic VLAN containment is disabled.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
•
The AVC feature is not active for any MSTI until it is globally enabled. To globally enable this feature,
use the
bridge auto-vlan-containment
command but do not specify an
msti_ id
.
•
When AVC is globally enabled, it is active for all MSTIs. To disable AVC for a single instance, use
the
disable
form of this command and specify the
msti_id
for the instance.
•
Use the
enable
form of this command and specify an
msti_id
to enable AVC for an instance that was
previously disabled.
•
An administratively set port path cost takes precedence and prevents AVC configuration of the path
cost. The exception to this is if the port path cost is administratively set to zero, which resets the path
cost to the default value.
•
Note that when AVC is disabled that a port assigned to a VLAN not mapped to a specific instance can
become the root port for that instance and cause a loss of connectivity between other VLANs.
•
AVC does not have any effect on root bridges.
