arp:

Syntax: arp <options>

Description:The arp command provides access to the ARP (Address Resolution Protocol) cache, enabling you to view cache data, delete entries, or add a static route. Super-user access is required to delete an entry or add a static route.

Each ARP cache entry lists the network interface that the device is connected to, the device’s network address or IP address, the device’s physical address or MAC address, and the media type of connection to the device. Media types display as numbers, which stand for the following states:

1 - Other

2 - Invalid entry (cannot ping device, timed out, etc.)

3 - Dynamic route entry

4 - Static route entry (not subject to change)

You can specify the arp command without options, or with one of the following options:

Options:	-a Views cache data
	-d Deletes an IP address entry. Requires
	additional arguments: <Interface Number>
	<IP address>
	-s Adds a static entry. Requires additional
	arguments: <Interface Number> <IP address>
	<MAC address>
	-f Flushes the ARP cache
