Chapter 56 IP Commands
SAM1316-22 User’s Guide

The first command changes the IP settings for the SAM1316-22’s uplink, downlink
and SAM1316-22 DSL ports. If you don’t enter the subnet mask, the system
automatically computes the subnet mask.
The second command changes the default gateway (next hop). This tells the
SAM1316-22 where to send packets that have a destination IP address that is not
on the same subnet as the SAM1316-22’s IP address.
The third command saves the new configuration to the nonvolatile memory.
For example, use the following command sequence sets the SAM1316-22 to have
192.168.1.3 as the IP address, 255.255.255.0 for the subnet mask and
192.168.1.233 for the default gateway.
The SAM1316-22 leaves the factory with a default management IP address of
192.168.1.1 and a subnet mask of 255.255.255.0, (ff:ff:ff:00 in hexadecimal
notation), and the default gateway set at 192.168.1.254. Make sure that you
configure the IP parameters correctly before you connect a SAM1316-22 to the
network, otherwise, you may interrupt services already running.
56.3 General IP Commands
The following is a list of general IP commands that help with the management of
the IP parameters.
</netmask> =
The bit number of the subnet mask of the IP address
you want to configure for SAM1316-22’s uplink,
downlink and SAM1316-22 DSL ports. To find the bit
number, convert the subnet mask to binary and add all
of the 1’s together. Take “255.255.255.0” for example.
255 converts to eight 1’s in binary. There are three
255’s, so add three eights together and you get the bit
number (24).
<ip> =
The default gateway IP address you want to configure
for the SAM1316-22.
