 describes some of the fields shown in the debug atm packet command output.

Several methods are available for upgrading software on the Cisco 1800 series integrated services 
fixed-configuration routers, including:

Copy the new software image to flash memory over the LAN or WAN while the existing Cisco IOS 
software image is operating.

Copy the new software image to flash memory over the LAN while the boot image (ROM monitor) 
is operating.

Copy the new software image over the console port while in ROM monitor mode.

From ROM monitor mode, boot the router from a software image that is loaded on a TFTP server. 
To use this method, the TFTP server must be on the same LAN as the router.

To recover a lost enable or lost enable-secret password:

 (for lost enable secret passwords only)

Recovering a lost password is only possible when you are connected to the router through the console 
port. These procedures cannot be performed through a Telnet session.

See the “Hot Tips” section on Cisco.com for additional information on replacing enable secret 
passwords.
