Software Upgrade Methods

Several methods are available for upgrading software on the Cisco Secure Router 520 Series 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.

Tab l e 12-3 debug atm packet Command Output Description

Field Description

ATM0 Interface that is generating the packet.

(O) Output packet. (I) would mean receive packet.

VCD: 0xnVirtual circuit associated with this packet, where n is some

value.

VPI: 0xnVirtual path identifier for this packet, where n is some value.

DM: 0xnDescriptor mode bits, where n is some value.

Length: nTotal length of the packet (in bytes) including the ATM

headers.
