I have two switches linked by a three port ISL. The first is a 3900 (FabOS v5.1.0d) the second a 4900 (FabOS v5.2.0). For some reason the three paths in the ISL will not link into a single trunk. All ports on both switches are licenced/enabled for trunking.

Nothing on port 3, but port 27 is in use.However, a little information that I forgot to add is that the switches are at different sites and are linked by DWDM system. Checking in more detail, the two ports that are trunking is on one fibre route, the other on a different. It now appears that there may be a config mismatch with the two routes. We are following that up with the supplier.
