Interoperability overview

This appendix explains how to set up your Fabric OS SAN and M-EOS SAN to route traffic through FC

router. Unlike with earlier releases of Fabric OS, you cannot mix Fabric OS v7.0.0 with M-EOS

switches in the same L2 fabric. In Fabric OS v7.0.0 and later releases, the only way you can

interoperate between Fabric OS and M-EOS fabrics is through FC router, which must connect to the

M-EOS fabric through an EX_Port.

When connected by FC router, the M-EOS firmware can operate in McDATA Open Mode

(interopMode 3) or McDATA Fabric Mode (interopMode 2), but the Fabric OS switches can only

operate in interopMode 0—the Brocade Native mode.

NOTE

In Fabric OS v7.0.0 and later releases, Fabric OS switches cannot operate in interopmode2 or

interopmode3.

Fabric OS provides the ability to configure any EX_Port to connect to an M-EOS fabric by using an

E_Port without disrupting the existing services. All EX_Port functions, such as fabric isolation and

device sharing, remain the same as when connecting to a Fabric OS fabric.

NOTE

M-EOS fabrics are supported only as edge fabrics and are not supported as backbone fabrics.

The Fibre Channel routing feature for M-EOS interoperability is not a licensed feature.

Release Compatibility

Table 82 outlines which releases of Fabric OS remain compatible with which releases of M-EOS,

when connected by FC router.
