I've recently brought an old Cisco AGS+ router on-line. It's running IOS\n10 right now, and I'm trying to upgrade it to something a little less\nancient. According to Cisco's web site, IOS 11.0 is the last version of IOS\nto support the AGS+, so I downloaded that image (gs3-k-mz.110-22a.bin).\n\nI tried copying it over from a TFTP server with the "copy tftp flash"\ncommand, and that worked. I then used the "boot system flash" configuration\ndirective to tell it to load the gs3-k-mz.110-22a.bin file. When I\nrestarted the router, though, it still came up with IOS 10. What am I doing\nwrong?
