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.

Table 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: 0x

Virtual circuit associated with this packet, where

is some

value.

VPI: 0x

Virtual path identifier for this packet, where

is some value.

DM: 0x

Descriptor mode bits, where

is some value.

Length:

Total length of the packet (in bytes) including the ATM

headers.
