Chapter 4. Connecting a c-series switch to a network device
This chapter provides information about performing the following tasks:
v
Securing access to the switch’s CLI by assigning passwords
v Configuring IP addresses for the management, Ethernet, virtual, and loopback
interfaces
v
Understanding how the management port functions
v
Connecting a switch to another networking device
v Testing network connectivity
This chapter also includes information about troubleshooting a network connection
in case a problem arises.
Assigning permanent passwords
By default, the switch’s CLI is not protected by passwords. To secure CLI access,
assigning a password is strongly recommended. (For additional information on
security, see the
NetIron Series Configuration Guide .)
The CLI contains the following access levels:
v
Privileged EXEC - This level is also called the Enable level and can be secured
by a password. You can perform tasks such as manage files on the management
module’s flash memory or a PCMCIA flash card in the management module’s
slots 1 or 2, save the system configuration to flash memory, and clear caches at
this level.
v CONFIG - The configuration level. This level lets you configure the system’s IP
address and configure routing features. To access the CONFIG mode, you must
already be logged into the Privileged level of the EXEC mode.
You can set the following levels of Enable passwords:
v
Super User - Allows complete read-and-write access to the system. This is
generally for system administrators and is the only password level that allows
you to configure passwords.
Note: You must set a super user password before you can set other types of
passwords.
v
Port Configuration - Allows read-and-write access for specific ports but not for
global (system-wide) parameters.
v Read Only - Allows access to the Privileged EXEC mode and CONFIG mode but
only with read access.
To set passwords:
1. At the opening CLI prompt, enter the following command to change to the
Privileged level of the EXEC mode:
NetIron> enable
NetIron#
2.
Access the CONFIG level of the CLI by entering the following command:
NetIron# configure terminal
NetIron(config)#
