Description of Arguments
to Query
Command or Query.
Used to set the IP address of the DHCP Server, in the format:
xxx.xxx.xxx.xxx, where:
xxx.xxx.xxx.xxx is the IP address
Example: <1/DRA=010.006.030.001
Returns >0001/DRA=0.0.0.0 when not configured.
Command or Query.
ARP Entry in format xxx.xxx.xxx.xxx|mm:mm:mm:mm:mm:mm
Where xxx.xxx.xxx.xxx = IP address.
mm:mm:mm:mm:mm:mm. = MAC Address.
Duplicate IP addresses are not allowed. They must also be locally
attached (on the same subnet as the Ethernet interface). Using a
different index with existing IP address may modify the existing
ARP entry, rather than creating new one.
Example:
<1/arp[1]=010.020.030.040|00:11:ab:33:44:66
Returns >0001/ARP! When there is no ARP entry.
Query Only.

Note: This command should be issued whenever a new ARP Entry
is added/deleted.
