Hi Aaron,
Can you try configuring the DWDM channel with frequency, instead
of channel. We run into a similar problem a while ago. Solution was to
configure with frequency.

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

I just checked this with my collegue...
The link from 9k to 9k passes through dwdm filters which filter on
channel 35
We pad that link and get around -12 to -15
What do you think about all this ?

Hi,
I'm not sure if this is relevant, but channel 53 is 194.55THz and 1540.95nm
(see here:
http://www.cisco.com/en/US/prod/collateral/modules/ps5455/data_sheet_78-458530.html).
193 THz is channel 22 and 1549.315nm is in fact channel 32. Output on both
routers shows the same values, so perhaps they do tune the optics the same way.
Is this a direct fibre, or does it go through some other equipment? Also -
what's the light budget of the link?
kind regards
Pshem
