I found out that on the ASR903 the EVC's appear fine in ifMIB, but a few issues. (at least for me on 3.7.2)

- Interface counters on EVC's don't seem accurate.  Some EVC's missing input counters and others don't seem to be showing traffic on the correct EVC's.  Kind of a mess.

- Counters will break completely on an RSP switchover.  They just zero out and stop incrementing.  (I have a TAC case/bug on this one)
