display pbb backbone-source-mac

Function

The display pbb backbone-source-mac command displays VSIs where B-SMAC addresses are configured.

Format

display pbb backbone-source-mac [ bSMacAddr ]

Parameters

Parameter	Description	Value
bSMacAddr	Specifies a B-SMAC address. If this parameter is not specified, VSIs where all B-SMAC addresses are configured will be displayed.	The value is a 12-digit hexadecimal number, in the format of H-H-H. Each H is 4 digits. If an H contains fewer than 4 digits, the left-most digits are padded with zeros. For example, e0 is displayed as 00e0. A MAC address cannot be FFFF-FFFF-FFFF or a broadcast MAC.

Usage Guidelines

Usage Scenario

In PBB VPLS, PEs and SPEs on the backbone network need to learn only the virtual B-MAC addresses (including B-SMAC and B-DMAC addresses), which reduces the number of MAC addresses learned and enhances network performance. To check VSIs where B-SMAC addresses are configured, run the display pbb backbone-source-mac command.

Precautions

If the pbb backbone-source-mac command has not been run to configure B-SMAC addresses, the display pbb backbone-source-mac command output will be blank.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display VSIs where B-SMAC address 00e0-fc00-1234 is configured.

Item	Description
B-SMAC	B-SMAC address.
VSI Name	Name of the VSI where a B-SMAC address is configured.
VSI Type	Type of the VSI where a B-SMAC address is configured, including: I-VSI: An I-VSI encapsulates packets into PBB frames and is bound to an AC interface for local CE identification. B-VSI: A B-VSI processes B-MAC addresses and uses the configured peer address to determine a PW's remote PE.
Total B-SMAC Number	Total number of B-SMAC addresses.
