The system image file name on a Cisco switch typically follows the format c2960x-universalk9-mz.152-2.E0.bin
, where the components indicate the model number (e.g., 2960x), feature set (e.g., universal), compression type (e.g., mz for compressed), and the software version (e.g., 15.2(2)E0). The exact naming convention may vary depending on the specific model and IOS version. It's important to check the documentation for your specific device to determine the correct image file name.
To set the boot environment variable to find the IOS image file on a Cisco switch, you use the command boot system flash:<image-filename>. This command specifies the IOS image file to be loaded from the flash memory during the boot process. After entering the command, remember to save the configuration with write memory or copy running-config startup-config to ensure the changes persist after a reboot.

No. An ISO image is a copy of the file system of any disc with an ISO9660 file system. It does not have to be a bootable image.
To show the contents of NVRAM on a Cisco switch, you can use the command show startup-config. This command displays the startup configuration file stored in NVRAM, which contains the settings and configurations that the switch will use when it boots up.
The kernel image is the file in /boot that has a name like "vmlinuz" in it.

When a Cisco router is booted up for the first time, or is reloaded, the router will look into its Non-Volatile RAM (NVRAM) for the startup configuration file. Setup Mode is usedto configure a Cisco router or switch after start up to create a startup configuration file.
it is a 'bitmap' image file used mainly by the windows operating system.
You don't "get" it. You create one from a directory containing the files you want to be in the file system image. A SquashFS image can be created by using the command mksquashfs /path/to/dir imagename.sqsh
On a Cisco switch, NVRAM (Non-Volatile Random Access Memory) is typically located within the switch's internal storage. It is used to store the startup configuration file, which is loaded when the switch boots up. You can access and manage the contents of NVRAM through the command-line interface (CLI) using commands like show startup-config and copy running-config startup-config.
The process of mounting is when you take a file (your image) and attach it to your file system so it can behave like it's a directory. Like if you mounted a disc image in Windows you could basically have a virtual "F:" drive (can be any letter) which when opened would be the contents of the disc image.
