I have a 6509 (Sup 720-3B) that upon reboot- just goes straight to the Rommon prompt. I've done everything according to the following article:
All of the information shows correct - even on the set printout on the rommon upon reboot, and once the router is booted. When you get to the rommon port- all you have to type is boot and it does. It just looks like autoboot is not on. Any ideas?
It should be 2102. Can you try setting it again on the RP and then save the config and rerun the 'remote command switch show bootvar' command. If it shows 0x2102 at next reload then I believe it should fix it. I dont exactly recall how I fixed it but I am sure if this is not the correct way someone else will provide you with the exact answer :- ).
