I noticed that one of my stand by sup720 are inactive and unavailable. Prior to this the card was removed into a new slot. The mac address of the card is recognized. When I intiate a show module the secondary sup720 is labled "unknown". How would I preconfigure this card to become a stand by? I also intiated a "cl mod-config" command versus a reload.
Most of the time, this is due to the first reason. you need to recover it manually by connecting a console cable to the standby's console and see what kind of prompt you get. Once connected you will probably get a "rommon1>" prompt, which means it did not booted up. Now, you need to determine which processor it is in rommon in. You can quickly check by issuing a "dir bootflash:". If you see a bootable native IOS image, which should look like "s72033..." then that is an image, try to boot it manually with "boot bootflash:".
Better yet, read through this link on how to recover sup IOS from corrupted or missing IOS:
IP routing should be enable by default. Are all the interface vlan up/up? make sure they are up/up. Can you post show ip route? do you see the directly connected interfaces (vlan interfaces)? if not, maybe ip routing had been somehow disable, to enable:
I know I have not lost my mind. I will reverify the vlan int are up and then issue the "IP ROUTING" command for the 100th time. lol. I Evertime I try to intiate the ip routing command I get a error "invalid input" when I am in the vlan int.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
