Symptom

VSAN segmentation reported by DCNM when fabric has discontinuous VSANs. This does not mean that there is VSAN isolation and does not affect traffic. However, if the VSAN is not enabled on the ISL, DCNM will consider the VSANs as segmented. There should be a warning in the documentation that this is expected behavior.

Conditions

VSANs are configured on different switches on the same fabric but not trunked across the ISLs.

Workaround

Add the VSAN to the trunked VSANs across the ISL.
