Release Information
Statement introduced in Junos OS Release 11.3 for EX Series switches.
Description
Configure switches running Junos OS Release 11.3 Multiple VLAN Registration Protocol (MVRP) to be compatible with MVRP running earlier release versions of Junos OS.
![]() | Note: Configure this statement on switches running Release 11.3 or later only if your network also includes switches running on earlier releases. |
You can recognize an MVRP version problem by looking at the switch running the older Junos OS version. Because a switch running an older Junos OS version cannot interpret an unmodified PDU from Junos OS Release 11.3, the switch does not add VLANs from the newer Junos OS version. When you execute the command show mvrp statistics in the switch running the older version, the values for Join Empty received and Join In received will incorrectly display zero, even though the value for MRPDU received has increased. 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 older Junos OS version.
To remedy these problems, configure add-attribute-length-in-pdu on all switches running Junos OS Release 11.3 or later.
