There are only two interfaces configured as a "trunk", so if it was a problem with the interface I would expect the one working monitor (of 3 total) would go down, or the rest of the bigip monitor's going to the LTM pair within the data center.

I agree it seems unlikely but there have been weirder bugs across all vendors in the networking space, and I have seen them first hand.
