Chapter 5. Getting familiar with c-series Command Line
Interface (CLI)
The c-series switches can be managed via Command Line Interface (CLI). The CLI
is a text-based interface accessible directly from a PC or terminal attached to the
device’s serial (Console) port or 10BaseT/100BaseTX Ethernet (management) port,
or from a Telnet connection to the PC or terminal.
Logging on through the CLI
Once an IP address is assigned to the management port on the B48C or B50C
switch, you can access the CLI through a PC or terminal attached to the device’s
serial (Console) port or 10BaseT/100BaseTX Ethernet (management) port, or from
a Telnet or SSH connection to the PC or terminal.
You can initiate a local Telnet, SSH or SNMP connection by specifying the
management port’s IP address.
The commands in the CLI are organized into the following levels:
v User EXEC - Lets you display information and perform basic tasks such as pings
and traceroutes.
v 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.
v
CONFIG - Lets you make configuration changes to the device. To save the
changes across software reloads and system resets, 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 direct or Telnet connection to the
switch 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/ server for authentication. .
Online 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:
NetIron (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.
