Description (partial)

ERSPAN packets from a Nexus 9000 are not decapsulated on the destination session which is another Cisco device.

N9k is configured as an ERSPAN source and the target is another Cisco device.  Due to a hardware limitation of the N9k platform the ERSPAN header cannot be interpreted for decapsulation.
