Logging on through the CLI
1
You can initiate a local Telnet or SNMP connection by attaching a 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 Dell PowerConnect 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/ server for
authentication. Refer to
Chapter 32, “Securing Access to Management Functions” .
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. An example is given below.
PowerConnect(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.
An example is given below.
