SBGxxxx/SB5120/SB5100/SB4220/SB4200/SB4100/SB3100/SB3100D Command Line Interface Notes

The CLI can only be accessed via an “rlogin” based Telnet client or the Diagnostic Console Cable and the DIAG port on the back of the modem, if available. The SURFboard cable modems do not come with a DIAG port and may be special ordered. Modems that are going to be used as Diagnostic Tools and use the CLI must have the “SHELL” version of modem firmware.

Connecting to the SURFboard Cable Modem via Diagnostic Console Cable:The CLI can be accessed via the Diagnostic Console Cable and the DIAG port on the back of the modem. This is typically done via “Windows HyperTerminal” with the following settings:Bits per second: 115,200 for SBGxxxx and SB5100, 38400 for 4X00, 9600 for SB5120, SB4220, 3100 and 3100D Data bits: 8 Parity: None Stop bits: 1 Flow Control: None Diagnostic cables are available through your Motorola Sales representative.

The following information pertains to the SB4X00 and SB3100 SURFboard Diagnostic CMs only:

Connecting to the SURFboard Cable Modem (SB4x00 and SB3100 only) via Ethernet and an “rlogin” based Telnet Client:Modem Ethernet IP address: 192.168.100.1To access CLI from client CPE, via Ethernet: rlogin 192.168.100.1To access CLI from HFC side: rlogin <modem IP address from DHCP>

Logging Into the SURFboard Cable Modem:Login name: targetPassword: first 15 digits of the unit serial number <It is best to copy these into a Notepad Window first, then copy/paste to the Terminal Window you are using for access.>
