Disabling ARP Entry

Sun Nov 21, 2021 12:25 pm

Hello.

At the ip arp print, I have dynamic entries, from dhcp, and static.

My question is, how to filter and remove ONLY ONE static entry using one command

Yes it it posible to remove a single Entry via CLI

Solution 1: Manually remove ARP-Entry
First you need to Print all entries via the "/ip arp print" command.
This will give you a list with a unique ID for each ARP-Element.
Exemple:
/ip arp print
 #    ADDRESS         MAC-ADDRESS       INTERFACE                                                                                                                                                
 0 DC 192.168.178.25 CA:25:07:F3:C9:A6 ether1   
 1 DC 192.168.178.26 CA:25:07:F3:C9:A7 ether1   
 2 DC 192.168.178.27 CA:25:07:F3:C9:A8 ether1 
 n DC 192.168.178.29 CA:25:07:F3:C9:A9 ether1  


After that you can delete the wanted ARP-Element via the ID
For exemple to remove 2 DC 192.168.178.27 CA:25:07:F3:C9:A8 ether1
/ip arp remove numbers=2

Solution 2: Remove via "Identifier"

Exemple: Remove all with IP 192.168.88.66
/ip arp remove [find address=192.168.88.66]
Exemple: Remove all with MAC CA:25:07:F3:C9:A8
/ip arp remove [find mac-address=CA:25:07:F3:C9:A8]
Exemple: Remove all from interface ether1
/ip arp remove [find interface=ether1]

Note that Conny's answer is based on RouterOS. This is the SwitchOS part of the forum, so that would not help if the OP is using SwitchOS.
