Verifying That MVRP Is Working Correctly
Purpose
After configuring your 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 mvrpGlobal MVRP configuration MVRP status : Enabled MVRP dynamic vlan creation: Enabled MVRP Timers (ms): Interface Join Leave LeaveAll -------------- ---- ----- -------- all 200 600 10000 xe-0/1/1.0 200 600 10000 Interface based configuration: Interface Status Registration Dynamic VLAN Creation -------------- -------- ------------ --------------------- all Disabled Fixed Enabled xe-0/1/1.0 Enabled Normal Enabled
- Confirm that MVRP messages are being sent and received
on your switch.
user@switch> show mvrp statistics interface xe-0/1/1.0MVRP statistics MRPDU received : 3342 Invalid PDU received : 0 New received : 2 Join Empty received : 1116 Join In received : 2219 Empty received : 2 In received : 2 Leave received : 1 LeaveAll received : 1117 MRPDU transmitted : 3280 MRPDU transmit failures : 0 New transmitted : 0 Join Empty transmitted : 1114 Join In transmitted : 2163 Empty transmitted : 1 In transmitted : 1 Leave transmitted : 1 LeaveAll transmitted : 1111
Meaning
The output of show mvrp shows that interface xe-0/1/1.0 is enabled for MVRP participation as shown in the status in the Interface based configuration field.
The output for show mvrp statistics interface xe-0/1/1.0 confirms that MVRP messages are being transmitted and received on the interface.
 | Note: You can identify an MVRP compatibility issue on EX Series switches by looking at the output from this command. If Join Empty received and Join In received incorrectly display zero, even though the value for MRPDU received has been increased, you are probably running different versions of Junos OS, including Release 11.3, 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). |
