IOS XR gives lots of options to manipulate the configuration, but I can't find one which lists what it was at a given point in time. All I can find is rollbacks, which can be viewed (absolutely or as diffs), which isn't exactly what you're looking for either. RP/0/RSP0/CPU0:lab#sh configuration ? commit Show commit information failed Contents of failed configuration history Display history of configuration events (up to 1500 events) inconsistency Configuration inconsistencies lock Configuration lock persistent Show persistent configuration removed Display configuration removed during install operations rollback Show rollback information running-config Current operating configuration sessions Users with active configuration sessions RP/0/RSP0/CPU0:lab#sh configuration We use RANCID here, so haven't had to confront your particular situation.
