The built-in commands listed in this section activate functions on the LM 
managed device or devices being accessed through Network Tools.

arp [options]

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 must specify the arp command with one of the following 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
