Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
For each bridge, you can display summary information about the number of bridge ports, number of MAC addresses, and so forth.
The hardware keyword displays detailed information, and is meant for field investigation by a specialized Cisco engineer.

time (VPLS)
To configure the maximum aging time, use the time command in l2vpn bridge group bridge domain MAC aging configuration mode. To disable this feature, use the no form of this command.
time {seconds}
no time {seconds}
Syntax Description
seconds
MAC address table entry maximum age. The range is from 120 to 1000000 seconds. Aging time is counted from the last time that the switch saw the MAC address. The default value is 300 seconds.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
If no packets are received from the MAC address for the duration of the maximum aging time, the dynamic MAC entry previously learned is removed from the forwarding table.
Task ID
Examples
The following example shows how to increase the maximum aging time to 600 seconds. After 600 seconds of inactivity from a MAC address, the MAC address is removed form the forwarding table.

type (VPLS)
To configure the type for MAC address aging, use the type command in l2vpn bridge group bridge domain MAC aging configuration mode. To disable this feature, use the no form of this command.
type {absolute | inactivity}
no type {absolute | inactivity}
Syntax Description
Defaults
By default, the inactivity type is configured.
Command Modes

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
In general, the type is set to inactivity. With an inactivity type configuration, a MAC address is removed from the forwarding table after the MAC address is inactive for the configured aging time.
With an absolute type configuration, a MAC address is always removed from the forwarding table after the aging time has elapsed once it is initially learned.
Task ID
Examples
The following example shows how to configure the MAC address aging type to absolute for every member of the bridge domain named bar:
