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 dynamic

entries remain in the ARP cache before they are removed.

■

By default, the system flushes the entry from the cache when it
reaches the age time.

■

A value of

indicates no age time, and the entry remains in the table

until you remove it with the

ip arp remove

option or flush the ARP

cache with the appropriate

flush

option.
