is there an easy way to copy new software updates to a router if it does not have a network connection? i need to download some software and transfer it to this router.
If it is a 6509 and not on the network then I would use a crossover cable to connect the PC to a switch port in the management VLAN. Assign an IP address to the management interface of the switch, configure a complementary IP address on the PC. Then use TFTP or FTP server on the PC to load the image to the switch.
Personal anonymous FTP server and a crossover connected to PC/Laptop would be the most expediant. Newer software revisions for some of the routers are getting too large for TFTP to be used, so it is a good idea to just start using SCP or FTP.
You can use x-modem from rommon, but even when you increase the speed of the console port it can take a very long time. If you attempt this via Hyperterm beware that it can/will time-out the transfer if you do not keep it (Hyperterm) running as your foreground process...
