Chapter 4Connecting Network Devices andChecking Connectivity
WARNIN G: The procedures in this manual are for qualified service personnel.
This chapter provides the details for connecting network devices and checking network connectivity.
The following 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.
