Managing The Device; Logging On Through The Cli - Foundry Networks Switch and Router Installation And Configuration Manual

Managing the Device

You can manage a Foundry device using any of the following applications:
• Command Line Interface (CLI) – a text-based interface accessible through a direct serial connection or a
Telnet session.
• Web management interface – A GUI-based management interface accessible through an HTTP (web
browser) connection.
• IronView – An optional SNMP-based standalone GUI application.

Logging on Through the CLI

Once an IP address is assigned to a Layer 2 Switch or ServerIron or to an interface on the Layer 3 Switch, you
can access the CLI either through the direct serial connection to the device or through a local or remote Telnet
session.
You can initiate a local Telnet or SNMP connection by attaching a straight-through RJ-45 cable to a port and
specifying the assigned management station IP address.
The commands in the CLI are organized into the following levels:
• User EXEC – Lets you display information and perform basic tasks such as pings and traceroutes.
• Privileged EXEC – Lets you use the same commands as those at the User EXEC level plus configuration
commands that do not require saving the changes to the system-config file.
• CONFIG – Lets you make configuration changes to the device. To save the changes across reboots, you
need to save them to the system-config file. The CONFIG level contains sub-levels for individual ports, for
VLANs, for routing protocols, and other configuration areas.
NOTE: By default, any user who can open a serial or Telnet connection to the Foundry device can access all
these CLI levels. To secure access, you can configure Enable passwords or local user accounts, or you can
configure the device to use a RADIUS or TACACS/TACACS+ server for authentication. See "Securing Access to
Management Functions" on page 3-1.
On-Line Help
To display a list of available commands or command options, enter "?" or press Tab. If you have not entered part
of a command at the command prompt, all the commands supported at the current CLI level are listed. If you
enter part of a command, then enter "?" or press Tab, the CLI lists the options you can enter at this point in the
command string.
If you enter an invalid command followed by ?, a message appears indicating the command was unrecognized.
For example:
BigIron(config)# rooter ip
Unrecognized command
Command Completion
The CLI supports command completion, so you do not need to enter the entire name of a command or option. As
long as you enter enough characters of the command or option name to avoid ambiguity with other commands or
options, the CLI understands what you are typing.
Scroll Control
By default, the CLI uses a page mode to paginate displays that are longer than the number of rows in your
terminal emulation window. For example, if you display a list of all the commands at the global CONFIG level but
your terminal emulation window does not have enough rows to display them all at once, the page mode stops the
display and lists your choices for continuing the display.
