is it possible to have AAA/Tacacs server per line-card on ASR 9000?

[mjaryanrad]

the question is could I have a AAA server per line-card, though I think it's possible to have AAA server per-SDR but aint sure! 

thanks indeed

that is correct, you can define a tacacs set per SDR, but the asr9k only supports one SDR (as opposed to CRS which can have multiples).

other then using command authorization or task groups, which will apply system wide, is the most granular control you have with tacacs in xr/a9k.
