Tools for Accessing and Controlling the Software

The primary means of accessing and controlling the JUNOSg software is the CLI.
The CMTS provides two ports on the Chassis Control Module for connecting external
management devices to the Routing Engine and hence to the JUNOSg software:
The CLI is the interface to the JUNOSg Internet software that you use whenever you access
the CMTS from the console or through a remote network connection. The CLI provides
commands used to perform various tasks, including configuring the JUNOSg software, and
monitoring and troubleshooting the software, network connectivity, and the CMTS hardware.
The JUNOSg CLI is a straightforward command interface. You type commands on a single
line, and enter the commands by pressing the Enter key. The CLI provides command help
and command completion, and also provides Emacs-style keyboard sequences that allow
you to move around on a command line and scroll through a buffer that contains recently
executed commands.

Software Monitoring Tools

You can monitor and troubleshoot the software, routing protocols, network connectivity, and
hardware by running commands from the CLI. The CLI provides commands that let you
display information in the routing table, display routing protocol-specific information, and
check network connectivity using the ping and traceroute commands.
The JUNOSg software includes Simple Network Management Protocol (SNMP) software,
which allows you to manage CMTSs. The SNMP software consists of an SNMP master agent
and a MIB II agent, and provides full support for MIB II SNMP Version 1 traps and Version 2
and Version 3 notifications.
The software also supports tracing and logging operations, which allow you to track events
that occur in the CMTS—both normal CMTS operations and error conditions—and to track
the packets that are generated by or pass through the CMTS. Logging operations use a system
log-like mechanism to record systemwide, high-level operations, such as interfaces going up
or down and users logging into or out of the CMTS. Tracing operations record more detailed
messages about the operation of routing protocols, such as the various types of routing
protocol packets sent and received, and routing policy actions.

Software Installation and Upgrade Procedures

The JUNOSg software is preinstalled in the CMTS. To upgrade the software, you copy a set of
software images over the network to the CMTS's flash disk using the CLI. The JUNOSg
software set consists of several images that are provided in individual packages or as a single
bundle. You normally upgrade all packages simultaneously. For information about installing
and upgrading JUNOSg software, see the JUNOSg software configuration guides.
! Fast Ethernet management port (Eth0)—Connects the Routing Engine to a management
LAN (or any other device that plugs into an Ethernet connection) for out-of-band
management of the CMTS. The Ethernet port can be 10 or 100 Mbps and uses an
autosensing RJ-45 connector.
! Console port (COM)—Connects a system console to the Routing Engine with an RS-232
serial cable.
