Syntax (EX Series)
The edit logical-systems hierarchy is not available on QFabric systems.
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 11.1 for the QFX Series.
Statement introduced in Junos OS Release 14.1X53-D20 for the OCX Series.
For Ethernet, Fast Ethernet, and Gigabit Ethernet interfaces only, configure Address Resolution Protocol (ARP) table entries mapping IP addresses to MAC addresses. You can enable backup VRRP routers to learn ARP requests for VRRP-IP to VRRP-MAC address translation. You can also set the time interval between ARP updates.
By default, an ARP policer is installed that is shared among all the Ethernet interfaces on which you have configured the family inet statement. By including the arp statement at the [edit interfaces interface-name unit logical-unit-number family inet policer] hierarchy level, you can apply a specific ARP-packet policer to an interface. This feature is not available on EX Series switches.
When you need to conserve IP addresses, you can configure an Ethernet interface to be unnumbered by including the unnumbered-address statement at the [edit interfaces interface-name unit logical-unit-number family inet] hierarchy level.
For EX-Series switches, set only the time interval between ARP updates.
For unicast MAC addresses only, if you include the publish option, the router or switch replies to proxy ARP requests.
seconds—Configure the ARP request delay in seconds. We recommend configuring a value in the range of 3 through 6 seconds.
Values: aging-timer minutes—Time between ARP updates, in minutes.
Range: 1 through 6,00,000
