Chapter 4
Connecting Network Devices and
Checking Connectivity
This chapter provides the details for connecting network devices and checking network connectivity.
WARNING: The procedures in this manual are for qualified service personnel.
Table 4.1 lists the tasks you must perform to connect your Foundry device, and shows where to get
troubleshooting information for any problems that can arise.
Assigning Permanent Passwords
By default, the CLI is not protected by passwords. To secure CLI access, Foundry strongly recommends assigning
passwords.
NOTE: You cannot assign a password using the Web management interface. You can assign passwords using
IronView Network Manager if an enable password for a Super User has been configured on the device.
The CLI contains the following access levels:
• User EXEC – The level you enter when you first start a CLI session. At this level, you can view some system
information but you cannot configure system or port parameters.
• 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 flash module, save the system configuration to flash, and clear
caches at this level.
