Disabling Mac Flush At The Bridge Port Level - Cisco ASR 9000 Series Configuration Manuallines

Disabling MAC Flush at the Bridge Port Level

The maximum MAC age for ASR 9000 Ethernet and ASR 9000 Enhanced Ethernet line cards is two hours.
Step 7
time { seconds }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-mac-aging)# time 300
Configures the maximum aging time.
• Use the seconds argument to specify the maximum age of the MAC address table entry. The range is from 300 to
30000 seconds. Aging time is counted from the last time that the switch saw the MAC address. The default value
is 300 seconds.
Step 8 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
Step 9
show l2vpn bridge-domain [ detail ]
Example:
RP/0/RSP0/CPU0:router# show l2vpn bridge-domain detail
Displays the details about the aging fields.
