VIEWING THE ARP TABLE ON AN ESXI HOST

If you are troubleshooting a network issue from an ESXi host it may be necessary for you to check the host’s arp cache. Running ‘arp’ doesn’t work on ESXi, instead use ‘esxcli network ip neighbor list’:

 # esxcli network ip  neighbor list
Neighbor      Mac Address        Vmknic    Expiry  State
