Page 1300 7750 SR OS Services Guide
arp-timeout
Syntax arp-timeout seconds
no arp-timeout
Context config>service>vprn>interface
config>service>vprn>sub-if>grp-if
Description This command configures the minimum time in seconds an ARP entry learned on the IP interface will
be stored in the ARP table. ARP entries are automatically refreshed when an ARP request or
gratuitous ARP is seen from an IP host, otherwise, the ARP entry is aged from the ARP table. If arp-
timeout is set to a value of zero seconds, ARP aging is disabled.
The no form of this command restores arp-timeout to the default value.
Default 14400 seconds
Parameters seconds — The minimum number of seconds a learned ARP entry will be stored in the ARP table,
expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned
ARP entries will not be aged.
Values 0 — 65535
authentication-policy
Syntax authentication-policy name
no authentication-policy
Context config>service>vprn>if
config>service>vprn>sub-if>grp-if
Description This command assigns an authentication policy to the interface.
The no form of this command removes the policy name from the group interface configuration.
Default no authentication-policy
Parameters name — Specifies the authentication policy name. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
delayed-enable
Syntax delayed-enable seconds [init-only]
no delayed-enable
Context config>service>vprn>sub-if
Description This command delays making interface operational by the specified number of seconds.
In environments with many subscribers, it can take time to synchronize the subscriber state between
peers when the subscriber-interface is enabled (perhaps, after a reboot). To ensure that the state has
time to be synchronized, the delayed-enable timer can be specified. The optional parameter init-only
can be added to use this timer only after a reboot.
