Manipulating the ARP table of the host machines - nova-dev-team/nova GitHub Wiki

View the ARP table cache (on modern Fedora/CentOS/RHEL, requires root privilege):

arp -e

View in traditional BSD form:

arp -a

Add a static entry to the ARP table cache (which will be marked with an M flag):

arp -s 192.168.122.4 fe:13:6d:74:d6:a3

Delete it:

arp -d 192.168.122.4
