Displaying VPLS information

Displaying the contents of the VPLS MAC database
The VPLS MAC database stores entries associating remote MAC addresses with VC LSPs and local
MAC addresses with CE devices. When a PE device receives a Layer 2 frame from an attached CE
device with a given destination MAC address, the PE device looks up the MAC address in the VPLS
MAC database and assigns the frame to the associated VC LSP. Each VPLS instance configured on
the PE device has a separate VPLS MAC database.
NOTE
It is possible in a loaded system that entries keep aging for few seconds. The age resets to zero (0)
after some time and entries remain intact.
Displaying VPLS MAC database entries on the Management Processor
To display the entire VPLS MAC database on the Management Processor (MP), enter the following
command.
Brocade# show mac vpls
Total VPLS mac entries in the table: 10 (Local: 5, Remote: 5)

When a given remote VPLS MAC address is learned on multiple uplink interfaces, the Port field in
the output of the show mac vpls command indicates “Mult.” instead of a port number. For example,
this abbreviation might appear when all of the following are true:
• The remote PE establishes multiple LSPs to this device.
• Packets from a remote VPLS MAC address are load balanced across these LSPs.
• The packets arrive on different MPLS uplink interfaces at this device.
