Step 4 Display the contents of Flash memory:
Router# pwd
flash:
Router# dir
1 -rw- 9950528 Jan 01 2000 00:48:59 c5350-js-mz.121-1.XD1.bin
32768000 bytes total (22817344 bytes free)
The Cisco IOS image named c5350-js-mz.121-1.XD1.bin is present.
Step 5 Inspect the NVRAM directory:
Router# dir nvram:
Directory of nvram:/
1 -rw- 0 <no date> startup-config
2 ---- 0 <no date> private-config
520184 bytes total (520184 bytes free)
In the example, the startup-config and private-config are present. The private-config file is a secure file
that is part of the startup configuration. It supports encryption technologies, but it is not user accessible.
Exploring Cisco IOS Software
This section describes what you need to know about the Cisco IOS software (the software that runs the
gateway) before you configure the gateway using the CLI. This section includes:
• Getting Help, page 1-6
• Understanding Command Modes, page 1-7
• Finding Command Options, page 1-7
• Undoing a Command or Feature, page 1-9
• Saving Configuration Changes, page 1-10
Understanding these concepts saves you time if you have no or minimal experience using the Cisco IOS
software.
Getting Help

the top level of the Cisco IOS software for the Cisco AS5350 or Cisco AS5400 universal gateway.
Note The examples in this guide show prompts for either a Cisco AS5350 or a Cisco AS5400 gateway.
However, regardless of the prompt or output shown, all examples apply to either type of gateway.
