Enabling MVRP
This section describes how to enable MVRP.
Configuration restrictions and guidelines
• MVRP can work with STP, RSTP, or MSTP, but not other link layer topology protocols, for example,
service loopback. Ports blocked by STP, RSTP, or MSTP can receive and send MVRP protocol packets.
For more information about service loopback, see "Configuring service loopback groups." For
more information about STP, RSTP, and MSTP, see "Configuring spanning tree protocols."
• Do not enable both MVRP and remote port mirroring on a port. Otherwise, MVRP may register the
remote probe VLAN to incorrect ports, which would cause the monitor port to receive undesired
duplicates. For more information about port mirroring, see Network Management and Monitoring
Configuration Guide.
• Enabling MVRP on a Layer 2 aggregate interface enables both the aggregate interface and all
Selected member ports in the link aggregation group to participate in dynamic VLAN registration
and deregistration.
Configuration procedure
To enable MVRP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable MVRP globally. mvrp global enable
By default, MVRP is globally
disabled.
To enable MVRP on a port, first
enable MVRP globally.
3. Enter interface view.
• Enter Layer 2 Ethernet interface
view or Layer 2 aggregate
interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use one of the commands.
4. Configure the port to permit
the specified VLANs. port trunk permit vlan { vlan-list |
all }
By default, a trunk port permits only
VLAN 1.
Make sure that the trunk port
permits all registered VLANs.
For more information about the
port trunk permit vlan command,
see Layer 2 — LAN Switching
Command Reference.
5. Enable MVRP on the port. mvrp enable
By default, MVRP is disabled on a
port.
