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 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 Figure 3-2.

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 >
