Verifying That MVRP Is Working Correctly
Purpose
 | Note: This task uses Junos OS for EX Series switches with support for the Enhanced Layer 2 Software (ELS) configuration style. If your switch runs software that does not support ELS, see Verifying That MVRP Is Working Correctly. For ELS details, see Getting Started with Enhanced Layer 2 Software. |
After configuring your EX Series switch to participate in MVRP, verify that the configuration is properly set and that MVRP messages are being sent and received on your switch.
Action
- Confirm that MVRP is enabled on your switch.
user@switch> show mvrpMVRP configuration for routing instance 'default-switch' MVRP dynamic VLAN creation : Enabled MVRP BPDU MAC address : Customer bridge group (01-80-C2-00-00-21) MVRP timers (ms) Interface Join Leave LeaveAll xe-0/1/1 200 1000 10000
- Confirm that MVRP messages are being sent and received
on your switch.

Meaning
The output of show mvrp shows that interface xe-0/1/1 is enabled for MVRP participation.
The output for show mvrp statistics confirms that MVRP messages are being transmitted and received on interface xe-0/1/1.
| Note: You can identify an MVRP compatibility issue by observing the output from this command. If Received Join Empty and Received Join In incorrectly display zero, even though the value for Received MVRP PDUs without error has been increased, you are probably running different versions of Junos OS on the switches in this network. Another indication that MVRP is having a version problem is that unexpected VLAN activity, such as multiple VLAN creation, takes place on the switch running the earlier release version. To remedy these problems, see Configuring Multiple VLAN Registration Protocol (MVRP) (CLI Procedure ). |
