Built-in Commands

arp

Description: 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 switch module 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 must specify the arp command with one of the options specified in this table.
