Syntax
global-mac-ip-table-aging-time seconds;
Hierarchy Level

Description
Configure the timeout interval systemwide for entries in the MAC-IP address bindings database.
On Junos OS Evolved QFX Series leaf devices in scaled EVPN-VXLAN networks with an edge-routed bridging (ERB) overlay, to avoid traffic loss, make sure that:
-
The MAC table aging time value is at least 10 minutes greater than the ARP aging timer.
-
The MAC-IP table aging time value is the same as the ARP aging timer.
The default ARP aging timer value is 20 minutes, which you can change using the
aging-timer option (value is in minutes) at the
[edit system arp]
hierarchy level.
The default value of this MAC-IP table aging time is the same as the default ARP
aging timer (1200 seconds=20 minutes). So if you change the ARP aging timer from
its default value, you should likewise change this
global-mac-ip-table-aging-time option to match.
The default MAC table aging time is 300 seconds=5 minutes. Change the MAC table
aging time using the global-mac-table-aging-time option (value is in seconds) at the [edit protocols
l2-learning] hierarchy level.
Options
| seconds | Specify the time that is elapsed before entries in the MAC-IP bindings database are timed out and deleted. |
Range: 60 through 1 million seconds
Default: 1200 seconds (20 minutes)
