> netmask aaa.bbb.ccc.ddd
where aaa.bbb.ccc.ddd is the desired netmask in the usual “dotted quad” format.
2.2.4.3 Default Gateway
When the local network includes one or more routers connecting to other networks, a default gateway should be
specified to indicate which is the most likely router to handle traffic to arbitrary IP addresses.
If DHCP is enabled, this manual setting is not used.
To set the default gateway, use the command
> gateway aaa.bbb.ccc.ddd
where aaa.bbb.ccc.ddd is the IP address of the default router in the usual “dotted quad” format.
2.2.4.4 DNS Servers
If either the timeserver or loghost (see following) are specified by name rather than IP number then a DNS is
needed to resolve the name.
If DHCP is enabled, then the DNS may be set automatically. However, if DHCP is disabled or if it does not
designate a DNS server, then the manual setting will apply.
Two DNS server may be specified, in which case the secondary server is used in the event the primary server is
unavailable.
To set the DNS server use the commands:
> dns pri aaa.bbb.ccc.ddd
> dns sec eee.fff.ggg.hhh
2.2.4.5 Timeserver
The modem does not have real-time clock hardware that will allow it to maintain a time reference when powered
off. However, during its startup procedure it will attempt to contact a timeserver on the network to set its clock to
the actual time. The time is only used for message logging and other diagnostic purposes and a correct time is
merely a convenience. Consequently, the availability of a timeserver is completely optional.
The factory set timeserver is us.pool.ntp.org, which refers to a collection of public timeservers generally available
on the Internet. A DNS server must be available to resolve that timeserver name into an IP address.
The protocol used to set the time is NTP (network time protocol). Any NTP server may be used as a timeserver.
To change the timeserver use the command:
> timeserver aaa.bbb.ccc.ddd
or
> timeserver hostname.domainname
where aaa.bbb.ccc.ddd is the IP address of the timeserver in the usual “dotted quad” format, or
hostname.domainname is the hostname and domain name. Note that there is no default domain name so it must be
explicitly specified with the hostname.
