[j-nsp] Urgent advice needed...possible CWDM module conflict, can't keep link.

[Morgan McLean]

Hi all.

I'm doing some work migrating from some brocade routers to a couple
MX480's. The client currently uses CWDM between two sites, and the brocades
handle the SFP's fine.

We popped them into the MX480's and link came up and down a few times
according to logs (though I could never catch it in an up state with show
commands), the green light came on and off a bunch, but link never came. An
EX4500 at the other end, which was previously interfacing with the brocade
fine, showed tons of link up/ down events in the logs, much more than the
MX showed.

Is this a sign of an optic incompatibility on the MX side? There was enough
signal for sure, and the brocades are able to operate with it so obviously
it wouldn't be signal related.

Any tips would be helpful.
