Hi,
I have 3 x MX240 connected in a triangle over CWDM equipment at distances of up to 30KM (1550nm, PROLABS SFP). There are 2 legs with one slightly longer than the other by a few KM. Two MX240 are at the same location connected by Multimode 10G XFP to complete the base of the triangle. Both legs go via different paths but terminate on the same MX240. All devices are running the same code.
The slightly shorter leg is UP/UP and working. However, the longer leg is not. Both show approximately the same information
from show commands.
CWDM equipment already trunks/multiplexes production colours/wavelengths without fault. I have just connected my new gear to it on a different wavelength.
One leg is working but the other is not. SFPS's are from the same manufacturer as is the CWDM equipment. The SFP's that aren't working have been swapped out with the ones that are and work OK (ish). Ports have also been changed. More of that later. Fibre has been cleaned and then replaced for brand-new. No difference.
However, both links are displaying very similar show output with no alarming.
There are two issues here.
Working leg and non-working leg
Neither work as plug and play. I have to reload or restart the DPC at a minimum (or reload) in order to bring the working leg online. But when it's online, it's stable.
Non-working leg
Although the show outputs are VERY similar, this refuses to come UP/UP.
Some show output for the non-working leg:
NB: Config is identical for working/non-working legs and output for the LASERS is virtually IDENTICAL. Configs have been modified ad-infinitum with no luck.
Any ideas of how to troubleshoot this further?
Best,
Chris
