IP Routing Features

Overview of IP Routing

You can increase the ARP age timeout maximum to 24 hours or more with this

command:

Syntax: [no] ip arp-age <[1...1440] | infinite>

Allows the ARP age to be set from 1 to 1440 minutes (24

hours). If the option “infinite” is configured, the internal ARP

age timeout is set to 99,999,999 seconds (approximately 3.2

years). An arp-age value of 0 (zero) is stored in the

configuration file to indicate that “infinite” has been

configured. This value also displays with the show commands

and in the menu display (Menu > Switch Configuration >

IP Config).

Default: 20 minutes.

ProCurve(config)# ip arp-age 1000

To view the value of ARP Age timer, enter the show ip command as shown in

Figure 3-2.
