ip arp age For CoreBuilder 9000: Applies to Layer 3 switching modules only.

Sets the age time for dynamic Address Resolution Protocol (ARP) cache

entries.

Valid Minimum Abbreviation

ip ar a

Important Considerations

■The age time determines how long, in minutes, that the dynami c

entries remain in the ARP cache before they are removed.

■By default, the system fl ushes the entry from the cach e when it

reaches the age time.

■A value of 0 indicates no age time, and the entry remains in the table

until you remove it w ith the ip arp remove option or flush the ARP

cache with the appropr iate flush option.
