They also frequently show up in error logs, e.g.

Jun  9 18:25:07  ar2.od cosd[1262]: COSD_GENCFG_WRITE_FAILED: GENCFG write failed for Classifier to IFL 698. Reason: File exists

Jun  9 20:03:43  cr1.td rpd[1039]: KRT ADD for 195.1.122.235/32 => { ifl 497 addr #0 0.19.5b.b9.d.c } failed, error "EINVAL -- Bad parameter in request".

I would much prefer if there was a *documented* command to translate
these references to interface/unit. Yes, I know it can be done by
accessing the PFE - but that's not an interface normal users are
encouraged to use.
