Configuring MAC Table Aging (CLI Procedure)
 | Note: This task uses Junos OS for EX Series 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 (CLI Procedure). |
The Ethernet switching table (or MAC table) aging process ensures that the EX Series switch tracks only active MAC addresses on the network and is able to flush out MAC addresses that are no longer used.
You can configure the MAC table aging time, the maximum time that an entry can remain in the Ethernet Switching table before it ages out, on all VLANs on the switch. This setting can influence efficiency of network resource use by affecting the amount of traffic that is flooded to all interfaces because when traffic is received for MAC addresses no longer in the Ethernet switching table, the switch floods the traffic to all interfaces.
To configure the MAC table aging time on all VLANs on the switch:
