show arp

Use the show arp command to display the Address Resolution Protocol (ARP)

cache.

show arp [ARP-MODE] [IP-ADDRESS [/ MASK]] [INTERFACE-ID]

Default None.

Command Mode User EXEC mode or any configuration mode.

Usage Guideline ARP establishes correspondences between network addresses (an IP address,

for example) and LAN hardware addresses (Ethernet addresses). A dynamic

record of each correspondence is kept in a cache for a predetermined amount of

time and then discarded. The predetermined amount of time can be changed

using the arp timeout command. If no arp mode argument is specified, then all

of the arp entries are displayed.

The user can select to display a specific ARP entry, all ARP entries, dynamic

entries, static entries, or entries associated with an IP interface.

Example This example shows how to display the ARP cache. The field of IP Interface is

indicated with the Interface ID.

Syntax Description

ARP-MODE (Optional) Displays the entries that are in a specific ARP mode. This argument

can be replaced by one of the following keywords:

dynamic—Displays only dynamic ARP entries. A dynamic ARP entry is learned

through an ARP request and completed with the MAC address of the external

host.

static—Displays only static ARP entries. A static ARP entry is a statically

configured (permanent) ARP.

IP-ADDRESS

[/MASK]

(Optional) Displays the entries associated with a specific host or network entry

that is associated with an external host.

INTERFACE-ID (Optional) Displays only the ARP table entries associated with this interface such

as, for example, a VLAN interface such as vlan100.
