Function

The display mac accounting command displays the MAC accounting statistics of an interface.

Format

display mac accounting interface interfacename [ mac mac-address ]

Parameters

Parameter	Description	Value
mac mac-address	Displays statistics about a specified MAC address. If no MAC address is specified, statistics about all MAC addresses is 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.
interface interfacename	Specifies an interface.	-

Parameter

Usage Guidelines

Usage Scenario

After MAC accounting is deployed on an interface, run the display mac accounting command to check service traffic statistics corresponding to MAC addresses learned by the interface. The statistics help determine whether the device is working properly.

NOTE:

If an interface is specified, MAC accounting statistics on the interface and its sub-interfaces are both displayed. If a sub-interface is specified, only MAC accounting statistics on the sub-interface are displayed.

Example

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