Question

A storage engineer is integrating a Cisco MDS 9000 fabric with a legacy third-party FC switch fabric that requires standards-based interoperability. The engineer must place the connecting VSAN into interop mode to allow the fabrics to merge without proprietary features breaking the ISL. What is a primary consequence the engineer must plan for when enabling interop mode 1 on the VSAN?

Accepted Answer

The Domain ID range is restricted to 97-127, so switch Domain IDs outside that range must be reassigned, requiring the VSAN to be temporarily suspended

Answer

All zoning is automatically converted from WWPN-based to port-based enforcement across both fabrics

Answer

FSPF is disabled on the VSAN and static routing must be manually configured on each ISL

Answer

Buffer-to-buffer credits are globally reset to 16 and cannot be modified while interop mode is active
