The command that will display the current contents of non-volatile random-access memory (NVRAM) is : show start-up configuration. On the screen you will see the following: "Switch#show startup-configuration".

Similarly, you may ask, which command will delete the contents of Nvram on a switch?

The erase startup-config command erases the contents of NVRAM and will put you in setup mode if the router is restarted.

Additionally, what is Nvram Cisco? RAM is short for Random-Access Memory. RAM on a Cisco router stores operational information such as routing tables and the running configuration file. NVRAM is non-volatile RAM. By "non-volatile", we mean that the contents of NVRAM are not lost when the router is powered down or reloaded.

Then, which command will display contents of Nvram?

To display the contents of NVRAM (if present and valid) or to show the configuration file pointed to by the CONFIG_FILE environment variable, use the show startup-config EXEC command.

How do I access Nvram?

Open up the Terminal in macOS, which you'll find in Applications > Utilities. Type nvram -xp , then press Enter. You'll see the complete contents of your NVRAM.

What does the command confreg 0x2142 provide? Explanation: The default configuration setting is 0x2102, which tells the router to load the IOS from flash and the configuration from NVRAM. 0x2142 tells the router to bypass the configuration in NVRAM so that you can perform password recovery.

To configure SSH on your router, you need to set the username command, the ip domain-name, login local, and the transport input ssh under the VTY lines and the crypto key command. However, SSH version 2 is suggested but not required.

The show processes exec command displays your router's CPU utilization and a list of active processes along with their corresponding process ID, priority, scheduler test (status), CPU time used, number of times invoked, and so on.

To copy the IOS to a backup host, which is stored in flash memory by default, use the copy flash tftp command.

copy running-config startup-config command

Solution(By Examveda Team)

The show running-config command shows the router, switch, or firewall's current configuration. The running-configuration is the config that is in the router's memory. This command can be abbreviated sh run.

What are two characteristics of RAM on a Cisco device? (Choose two.)

• RAM provides nonvolatile storage.
• The configuration that is actively running on the device is stored in RAM.
• The contents of RAM are lost during a power cycle.
• RAM is a component in Cisco switches but not in Cisco routers.

Immediately after you type a command in the global configuration mode, it will be stored in the running configuration. A startup configuration is stored in the nonvolatile memory of a device, which means that all configuration changes are saved even if the device loses power.

Why does the router respond with the startup-config is not present message? It displays this message because the configuration file was not saved to NVRAM. Currently it is only located in RAM. To configure parameters on a router, you may be required to move between various configuration modes.

Non-volatile random-access memory

Flash memory content is retained by the router on power-down or reload. RAM is short for Random-Access Memory. NVRAM is non-volatile RAM. By "non-volatile", we mean that the contents of NVRAM are not lost when the router is powered down or reloaded.

bootflash: Boot Flash memory. Bootflash is a generic term normally used for the flash of both route flash and switch flash. disk0: Rotating media. flash: Flash memory.

Flash memory is an Electronically Erasable and Re-Programmable memory chip. The Flash memory contains the full Operating System Image (IOS, Internetwork Operating System). This allows you to upgrade the OS without removing chips. Flash memory retains content when router is powered down or restarted.

Stands for "Non-Volatile Random Access Memory." NVRAM is a type of RAM that retains data after the host device's power is turned off. Two common types of NVRAM include SRAM and EEPROM. Therefore, EEPROM does not need a battery or other power source to retain data.

The IOS is stored in a memory area called flash. The flash allows the IOS to be upgraded or stores multiple IOS files. In many router architectures, the IOS is copied into and run from RAM. A copy of the configuration file is stored in NVRAM to be used during startup.
