This is the minimum number of entries to keep in the ARP

fewer than this number of entries in the cache.

description: Configures sysctl net.ipv4.neigh.default.gc_thresh2 value.
|
|
This is the soft maximum number of entries to keep in the

ARP cache. The garbage collector will allow the number of

entries to exceed this for 5 seconds before collection will

be performed.
