I have an odd event happening. I have two chassis that I am trying to trunk together.
The first chassis is a 6509 with a S720-10G sup module. The second chassis is a 6504 with a Sup32-10GE-3B sup.
I am using an X2-LR in the S720-10G slot 1 and an Xenpack-LR in the Sup32-10GE-3B slot 1.
I can bring the trunk up and it runs fine for a while. Then at random times, it just drops. There is nothing in the log files to tell me what is happening. The only thing there is the adjecency notices. I have tried everything I know:
Changed the patch cables
Change the GBICS
Tried every configuration (auto, on, desirable, etc).
I can not get this stupid trunk to stay live.
I do get some crc errors on the trunk and a couple giants as the link comes up .. but, that is about it...
The only other piece to this is I have 50 micron fiber between them.
When I read the docs on the transcievers, I think the issue may be the 50 micron fiber. But, I also wonder if the xenpack and the x2 are truly compatiable.
Has anyone had this scenario or suggestions on how to move forward to make this work?
In your original message, you said it is a 50 micron fiber and the optic is X2-10GB-LR and XENPAK-10GB-LR? I just want to make sure you are not using the LRM optic. If that is true, then the fiber is MMF and the spec for the X2-10GB-LR and XENPAK-10GB-LR require SMF
