Static ARP Entery in CISCO Switch



Synatax :
arp <IP> <MAC> arpa
arp x.x.x.x 0000.0000.000 arpa



Example
R1(config)#arp 10.1.1.25 00ac.a1f3.01ab arpa



Notes :
  • static ARP entries are more preferred as they are administratively added.
  • this way you can ensure that even if you have an ip duplicate the important devices in your network will be always accessible .
