CHAPTER 12 TCP/IP CONFIGURATION
12-12
The leftmost group of digits in your IP address can identify the type of network you
have. The value of this group ranges from 192 through 255 for Class C networks
(e.g., 192.189.207.3), 128 through 191 for Class B networks (e.g.,128.10.1.30), and 1
through 127 for Class A networks (e.g., 13.27.7.1).
If you have a gateway (router), enter its address with the command SET IP ROUTER
routeraddress, where routeraddress is the desired IP address of the gateway you wish
to assign to the print server. For example:
Local> SET IP ROUTER 192.189.207.1
To verify that you have entered the IP information correctly, type SHOW IP.
Type EXIT or CTR-D (i.e., hold down the control key and type "D") to end the
remote console session.
