Media Flow Controller Administrator's Guide

Connecting and Logging In

You can connect to the CLI with SSH, Telnet (after enabled; Telnet is disabled by default), or
serial console using the IP address of your Media Flow Controller. The Media Flow Controller
responds with a login prompt. Enter admin as the user; there is no default password. After you
have connected, you must enter enable and then configure terminal in order to begin
configuring Media Flow Controller.
Likewise, you can log in to the Web-based interface by entering the IP address in a browser
window and using admin as the login name. The Management Console has a subset of the
CLI commands, but is good for simple or First Day configurations.
Each user account has at least one privilege level that determines which commands they can
issue and what CLI modes they can access:
•
Administrator (admin): Full privileges. Can enter Enable mode and Config mode.
•
Monitor (monitor): Can read all data and perform all actions, but not change any
configuration. Can enter Enable mode from Standard mode but cannot change
configurations.
•
Unprivileged (unpriv): Can issue a small subset of commands including debugging and
show commands. Can log in to Standard mode only.

Using the Command Modes

When you log into the management shell over SSH (or optionally TELNET, if enabled; this is
not recommended) you are in the lowest tier, Standard mode; only show, help, diagnostic
commands and a few others can be entered. You get into Enable mode by issuing the enable
command. In Enable mode you can view current configurations but not make configurations.
You need to enter Configure mode to make any changes. The CLI can be in one of three
modes, which determine which set of commands are available.
•
Standard mode—When the CLI is launched, it begins in Standard mode. This is the most
restrictive mode and only has commands to query a restricted set of state information. You
cannot take any actions that would directly affect the system, you cannot change settings.
•
Enable mode—The enable command moves you to Enable mode. This has commands
to view all state information, and take certain kinds of actions like rebooting the system,
but does not allow any configuration to be changed. Its commands are a superset of those
in Standard mode. Enter disable to exit Enable mode.
•
Configure mode—The configure terminal command moves you to Configure mode.
This has a full unrestricted set of commands to view anything, take any action, or change
any configuration. Its commands are a superset of those in Enable mode. Enter exit to
leave Configure mode.
•
Prefix mode—Some commands have a prefix mode; that is, when you enter a keyword,
you enter a mode for that configuration. For example:
test-vos (config) # accesslog
test-vos (config accesslog) #
When in the prefix mode, you can only make configurations for that command set and
typing ? (question mark) shows you only the options for those configurations. To leave the
prefix mode, type exit.
