arp
(2016-11-22)
Problem
arp -a is too brief. In keeping with the new trend of banging in long command names, we need a suitable long command that does the same thing.
Solution
# ip neighbour show
+1 for accepting Canadian spelling.
Other useful things that you can do:
| Command | Effect |
|---|---|
ip neighbor add 172.30.1.236 lladdr 00:1c:23:65:b9:20 dev ens192 nud permanent |
Create a static arp entry for 172.30.1.236 on interface ens192 |
ip neighbor change 172.30.1.236 lladdr 00:1c:23:65:b9:20 dev ens192 nud permanent |
Change an existing entry into a permanent static entry. I had to do this because the arp table had an entry of FAILED that I couldn't flush or del away. |
