Has anyone come across the following problem before.
Certain connections will intermittantly lockup and not pass traffic across UXM trunks. If rerouted to an alternative path, it starts working again. The trunks in question are error free and other connections on the trunk work fine. This is very intermittant and not possible to replicate / simulate. I have had a case logged with cisco for 6 months now and they have not been able to find a fault. I have had IGX design engineers dialled into my network to diagnose with no luck although they can see this happening.
