NAME
arp - Linux ARP kernel module.
...
SYSCTLS
ARP supports a sysctl interface to configure parameters on
a global or per-interface basis. The sysctls can be
accessed by reading or writing the
/proc/sys/net/ipv4/neigh/*/* files or with the sysctl(2)
interface. Each interface in the system has its own
directory in /proc/sys/net/ipv4/neigh/. The setting in
the `default' directory is used for all newly created
devices. Unless otherwise specified time related sysctls
are specified in seconds.
....
base_reachable_time
Once a neighbour has been found, the entry is con
sidered to be valid for at least a random value
between base_reachable_time/2 and 3*base_reach
able_time/2. An entry's validity will be extended
if it receives positive feedback from higher level
protocols. Defaults to 30 seconds.
delay_first_probe_time
Delay before first probe after it has been decided
that a neighbour is stale. Defaults to 5 seconds.
