Usage Guidelines

Usage Scenario

After multiple bridge domains are configured on a device, to view the aging time for dynamic MAC address entries in a specified bridge domain, run the display mac-address aging-time bridge-domain command in the BD view. To set the aging time, run the mac-address aging-time (Bridge domain view) command. The command output helps verify the configuration and analyze faults.

Precautions

If a MAC address entry does not age, the aging time in the command output is 0s.

If a great number of bridge domains are configured on a device, configure bd-id in the display mac-address aging-time bridge-domain command to view information about a specified bridge domain.

Example

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

# Display the aging time of all dynamic MAC address entries in all bridge domains.

<HUAWEI> display mac-address aging-time bridge-domain
  Bridge-domain                   Aging Time(sec)
  10                              90
  20                              600

# Display the aging time of all dynamic MAC address entries in bridge domain 20.

<HUAWEI> display mac-address aging-time bridge-domain 20
  Bridge-domain                   Aging Time(sec)
  20                              600
