Managing a Cisco Internetwork - Managing a Cisco Internetwork (2)

All Cisco routers have a default configuration register setting of 0x2102, which tells the router to load the IOS from flash memory and the configuration from NVRAM.

The show version command provides you with the current configuration register setting.

Since the question never mentioned anything about a suspended session, you can assume that the Telnet session is still open, and you would just type exit to close the session.

The default configuration setting of 0x2102 tells the router to look in NVRAM for the boot sequence.

The command traceroute (trace for short), which can be issued from user mode or privileged mode, is used to find the path a packet takes through an internetwork and will also show you where the packet stops because of an error on a router.

The command copy tftp flash will allow you to copy a new IOS into flash memory on your router.

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

To keep open one or more Telnet sessions, use the Ctrl+Shift+6 and then X keystroke combination.
