Hello, I wanted to share this for others. I had received a 10G DWDM optic from my carrier and it wouldn’t work. Turns out the optic did not have the reach programmed into it and JunOS didn’t handle this well.
I addressed this by writing the reach into byte 0x3 on the optic, which for the FS ones required writing a password to change the byte, which was 0x00000000 for this FS optic.

It’s interesting that an ethernet-only platform even allowed OC3 to be a default. Have a good weekend. - jared _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
