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
