[c-nsp] ipodwdm - asr 9000

If the filters only allow channel 35 that's what the optics should be
tuned to. I'm not sure how to verify that, since clearly you set the
channel and yet the show commands do not confirm that.
All that comes to mind is to confirm the actual frequencies of those
channels on the DWDM filters (we've encountered some incompatibilities
with Ericsson OTN equipment - their bands didn't always exactly
aligned with ITU channels).

What software version are you running on those ASR9k?

kind regards
Pshem
