To copy the contents of NVRAM to a TFTP server on a Cisco device, you can use the command: copy nvram tftp After executing this command, you will be prompted to enter the TFTP server's IP address and the filename for the backup. Make sure that the TFTP server is reachable and properly configured to accept the transfer.

NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from the CMOS battery installed in your motherboard. It keeps track of various system parameters such as serial number, Ethernet MAC (Media Access Control) address, HOSTID, date of manufacture, etc. NVRAM is therefore a type of non-volatile memory that offers random access SYED OWAIS ALI{TECHNICAL SPECALIST}
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.
The command "show vtp status" will show you how many vlans are supported by the switch. The Cisco 2950 switch supports up to 64 VLANs.
NVRAM Stores startup-config. The IOS (Internetwork Operating System) is stored in the flash. Both flash and NVRAM are non volatile storages but there is a major difference.
Cisco IOS uses a command line interface (CLI) for inputting commands when configuring Cisco Routers
