Configuring MVRP
CAUTION:
•
MVRP and service loopback are mutually exclusive.
• MVRP can work with STP, RSTP, or MSTP, but not other link layer topology protocols, including PVST,
RRPP, and Smart Link. Ports blocked by STP, RSTP, or MSTP can receive and send MVRP protocol packets.
For more information about STP, RSTP, MSTP, and PVST, see "Configuring the spanning tree." For more
information about RRPP and Smart Link, see High Availability Configuration Guide.
• Do not enable both MVRP and remote port mirroring on a port. Otherwise, MVRP might register the
remote probe VLAN to unexpected 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.
• MVRP runs on a per-MSTI basis. When configuring MVRP, make sure all MSTIs in the network are
effective and each MSTI is mapped to an existing VLAN on each device in the network.
Before enabling MVRP on a port, you must enable MVRP globally. You can configure MVRP only on trunk
ports, and you must assign the involved trunk ports to all dynamic VLANs.
To configure 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.
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 as a trunk
port.
port link-type trunk
By default, the link type of a port is
access.
For more information about the
port link-type trunk command, see
Layer 2 — LAN Switching
Command Reference.
5. Configure the port to permit
all VLANs.
port trunk permit vlan all
By default, a trunk port permits only
VLAN 1.
For more information about the
port trunk permit vlan all
command, see Layer 2 — LAN
Switching Command Reference.
