The router was reloaded but came up with an old (12.3
(5a) IOS that does not support the SDSL card providing a backup uplink.
On a further reboot the correct IOS came back up and the config was amended in order that the SDSL interface could be used again.
The boot statement of the device contained the correct IOS - Version 12.4
The router is a 2651XM running c2600-entservicesk9-mz.124-8.bin
boot system flash c2600-entservicesk9-mz.124-8.bin
Is there a bug that can cause that?
I have included below a show flash
