[c-nsp] 2811 router doesn't recognize T-1 WICs?

Dave,

That's a great idea. If you ask them to make it viewable then I'll be
able to track the progress of these bugs. I'd like to use the 2811s and
those WICs but now I'm wondering if I should cancel my order and stick
with a 2620XM instead. Does anyone know if the V2 WICs are experiencing
problems when used in the 2600XM series or does this just happen in the
2800 series routers?

Thanks,
John

For the record.

If you have a case open and the bug is not
viewable on CCO then ask the TAC engineer
to make it viewable.

There are usually only two reasons a bug
is not viewable on CCO.

a) PSIRT
b) It was found internally in testing and was thought
   to only exist in images that were never released to customers.
   If it's determined it was in an image released to a customer
   the correct procedure is to modify that bug so it is visible
   on CCO with the correct enclosures (ie: Release-note).

...or there is a 3rd reason and someone just messed up.

Bottom line, if you encounter a bug not viewable on
CCO that you are hitting ask them to make it viewable.
