Arguments for
Command or
Response 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.
Note: 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.
Returns the number of static arp entries.
Note: This command should be issued whenever a new ARP Entry is
added/deleted.
Command only.
Delete the ARP entry associated with the specified IP Address.
xxx.xxx.xxx.xxx IP address of ARP entry to delete.
Example: <1/ARD=192.168.001.100
Command or Query.
Set the IGMP Query period in seconds while modem acting as IGMP Server.
Command or Query.
Set the Maximum response time for the IGMP Query in seconds. Should always be
2 less than query period. The range is 1 to (IGQ – 2). If IGQ is at 30, then IMR can
be set from 1 through 28.
