Your ARP cache is overflowing negatively impacting users experience on your network. Which
command can you issue to increase the ARP cache on the fly? You do not need this to survive
reboot.
A.
arp cache table > 1024
B.
echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
C.
You cannot increase the size of the ARP cache on the fly.
D.
Modify the /etc/sysctl.conf: net.ipv4.neigh.default.gc_thresh3 = 1024.
B
To increase the threshold levels for ARP cache on-the-fly, run:
[Expert@HostName]# echo 256 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
[Expert@HostName]# echo 512 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
[Expert@HostName]# echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh3

I think for Gaia we should use
>set arp table cache-size
>save config
But for Splat option B will work.
