20.2 Determining the Current Kernel Threshold Value

To determine the current kernel threshold value on the Orchestration Server, use the following commands to determine the values for each threshold:

  • # cat /proc/sys/net/ipv4/neigh/default/gc_thresh1

    The command might result in a displayed value like this:

    # cat /proc/sys/net/ipv4/neigh/default/gc_thresh1
128

  • # cat /proc/sys/net/ipv4/neigh/default/gc_thresh2 512

    The command might result in a displayed value like this:

    # cat /proc/sys/net/ipv4/neigh/default/gc_thresh2
512

  • # cat /proc/sys/net/ipv4/neigh/default/gc_thresh3

    The command might result in a displayed value like this:

    # cat /proc/sys/net/ipv4/neigh/default/gc_thresh3
1024

You can also use this command:

#sysctl -A|grep ipv4|grep default |grep gc_thresh

The result is a listing similar to the following:

net.ipv4.neigh.default.gc_thresh3 = 1024
net.ipv4.neigh.default.gc_thresh2 = 512
net.ipv4.neigh.default.gc_thresh1 = 128
