Configuring MAC Table Aging
MAC table aging ensures that a switch tracks only active nodes on the network and that it is able to flush out network nodes that are no longer available.
To manage MAC entries more efficiently, you can configure an entry’s aging time, which is the maximum time that an entry can remain in the MAC address table before it is deleted because it has reached its maximum age.
 | Note: This task uses Junos OS for QFX3500 and QFX3600 switches with support for the Enhanced Layer 2 Software (ELS) configuration style. If your switch runs software that does not support ELS, see Configuring MAC Table Aging. For ELS details, see Getting Started with Enhanced Layer 2 Software. |
You can use the set-mac-table-aging-time command to configure how long entries remain in the Ethernet switching table before expiring. Here the VLAN is employee-vlan:
