set arp
Chapter 2 Command Descriptions 89
set arp
Device support This command is supported in all devices.
Purpose Manually configures an entry in the Address Resolution Protocol (ARP)
table, or displays the contents of the ARP table.
The ARP table contains the Ethernet-to-IP address mappings of other
devices on the LAN, which is required to communicate with these devices.
The ARP protocol updates this table automatically, so manual modification
is seldom required.
Required

The root user can configure ARP table entries. Normal users can display
ARP table entries.

Options ether=etaddr

ARP table.
tim2liv=time
The time, in seconds, to keep an entry in the ARP table. The range is 0
to 1200 seconds. The default is 0, which means the entry will never time
