IP DNS commands
set ip dns domain-name
domain_name
Specifies the default domain name for your network. When an application needs to resolve a host name, it
appends the default domain name to the host name and asks the DNS server if it has an address for the “fully
qualified host name.”
set ip dns primary-address
ip_address
Specifies the IP address of the primary DNS name server.
set ip dns secondary-address
ip_address
Specifies the IP address of the secondary DNS name server. Enter
0.0.0.0
if your network does not have a sec-
ondary DNS name server.
set ip dns proxy-enable [ on | off ]
This allows you to disable the default behavior of acting as a DNS proxy. The default is
on
.
IP IGMP commands
Multicasting
is a method for transmitting large amounts of information to many, but not all, computers over
an internet. One common use is to distribute real time voice, video, and data services to the set of computers
which have joined a distributed conference. Other uses include updating the address books of mobile com-
puter users in the field, or sending out company newsletters to a distribution list.
Since a router should not be used as a passive forwarding device, ARRIS Gateways use a protocol for forward-
ing multicasting: Internet Group Management Protocol (IGMP).
ARRIS Gateways support IGMP Version 1, Version 2, or Version 3.
IGMP “Snooping”
is a feature of Ethernet layer 2 switches that “listens in” on the IGMP conversation between
computers and multicast routers. Through this process, it builds a database of where the multicast routers
reside by noting IGMP general queries used in the querier selection process and by listening to other router
protocols.
