C. Router CLI Commands, Codes, and Designations

ARP Commands

Address Resolution Protocol (ARP) commands are used to create entries in the ARP table, specify how long the information will be retained, and remove dynamic entries in the table.

Table C-7. ARP Commands

arp ip-address mac-address arp-type

no arp ip-address [mac-address arp-type]

Minimum Access Level: Administrator

Command Mode: config

Allows you to create or delete a single, static ARP table entry. Static ARP entries created with this command are permanent and are retained across resets/power cycles. Up to the maximum number of static ARP entries specified may be entered. There are no static ARP entries by default.

ip-address– The IP address of the ARP entry to be created or deleted.

mac-address– MAC address.

arp-type– Specifies the ARP type. Valid ARP type is arpa, the standard Ethernet-style ARP (RFC 826).

arp timeout time

no arp timeout [time]

Minimum Access Level: Administrator

Command Mode: config-if(Ethernet)

Allows you to specify the amount of time that ARP information is retained in the ARP cache. The no arp timeout command restores the default ARP timeout value.

Example: arp timeout 28000

NOTES:

The amount of time the device waits before reattempting to acquire ARP information for incomplete entries is 5 seconds and is not configurable.

The internal ARP timeout timer has one minute precision, so the ARP timeout is implemented by rounding up to the nearest minute.

time – The ARP timeout value in seconds. Valid range is 1–4294967 seconds. The default is 14400.

clear arp-cache

Minimum Access Level: Administrator

Command Mode: Standard

Deletes all dynamic ARP table entries from the ARP cache.
