MVRP is disabled by default. You only need to perform this procedure if you have
previously enabled MVRP.
To disable MVRP on all trunk interfaces on the switch:
[edit protocols mvrp]
user@switch# set disable
To disable MVRP on a specific trunk interface:
[edit protocols mvrp]
user@switch# set disable interface xe-0/0/1.0
Dynamic VLANs can be created on interfaces participating in MVRP by default. Dynamic
VLANs are VLANs created on one switch that are propagated to other switches
dynamically; in this case, using MVRP.
Dynamic VLAN creation through MVRP cannot be disabled per switch interface. To disable
dynamic VLAN creation for interfaces participating in MVRP, you must disable it for all
interfaces on the switch.
To disable dynamic VLAN creation:
[edit protocols mvrp]
user@switch# set no-dynamic-vlan
The timers in MVRP define the amount of time an interface waits to join or leave MVRP
or to send or process the MVRP information for the switch after receiving an MVRP PDU.
The join timer controls the amount of time the switch waits to accept a registration
request, the leave timer controls the period of time that the switch waits in the Leave
state before changing to the unregistered state, and the leaveall timer controls the
frequency with which the LeaveAll messages are communicated.
The default MVRP timer values are 200 ms for the join timer, 1000 ms for the leave timer,
and 10000 ms for the leaveall timer.
BEST PRACTICE: Maintain default timer settings unless there is a compelling
reason to change the settings. Modifying timers to inappropriate values might
cause an imbalance in the operation of MVRP.
To set the join timer for all interfaces on the switch:
[edit protocols mvrp]
user@switch# set interface all join-timer 300
To set the join timer for a specific interface:
