CLI debugging

Hi, I wanted to debug the states of a neighbor, but I cannot seem to figure out how to change debugging on the command-line in a way that *seems* according to the argument options: debug (<protocol> | <pattern> | all) (all | off | { states | routes | filters | interfaces | events | packets }) Control protocol debugging via BIRD logs BIRD 1.6.0 ready. bird> debug all states syntax error bird> debug all events syntax error bird> debug cogent states syntax error bird> debug cogent events syntax error bird> debug cogent all bird> The 'all' works, but the others do not. Do I misunderstand the argument option specification? Thanks, micah
