Here's what I do when I need to upgrade a router's IOS and I don't have LAN
or sync serial access to it for TFTP purposes.
1. Plug the following code into the router to configure it for PPP on the
AUX port:
interface Async1
ip address 192.168.255.254 255.255.255.252
encapsulation ppp
no ip route-cache
async default routing
async mode dedicated
!
ip default-gateway 192.168.255.253
!
line con 0
line aux 0
no exec
exec-timeout 0 0
modem InOut
transport input all
stopbits 1
rxspeed 38400
txspeed 38400
flowcontrol hardware
2. Configure a "dialup networking" entry on my Windows PC using the
NULL-MODEM driver available from the following Cisco URL:
http://www.cisco.com/warp/public/471/103.html
Configure the dialup networking entry to use 192.168.255.253 as the IP
address of the dialing interface.
3. Start up the TFTP server on my Windows PC.
4. Connect to the router from my Windows PC using the dialup networking
entry.
5. Open up the router console and use regular TFTP commands to pull the
image across.
Depending on what family of router you have (2500, 2600) your AUX port will
accommodate up to 38400 (older families) or 115200 (newer families).
Hope this helps someone!
Paul
