Interoperability With Legacy Fcr Switches; Backward Compatibility - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Interoperability with legacy FCR switches

The following interoperability considerations apply when administering legacy FCR switches in the same
backbone (BB) fabric as switches supporting Fabric OS v5.2.x:
• When a legacy switch is connected to the fabric, a RAS log message is issued indicating that the
capability of the backbone (BB) fabric is lower as legacy FCR switches (those with XPath OS and Fabric
OS v5.1) support lower capability limits.
• If an XPath OS switch joins the BB fabric, a RAS log message is issued indicating that the
backbone-to-edge (B2E) fabric is not supported with the XPath OS switch.
For the exact RAS log message descriptions, see the following RAS logs: FCR_1055, FCR_1056, and
FCR_1073.

Backward compatibility

In a fabric with Secure Fabric OS enabled, the edge fabric must have Fabric OS v3.2, v4.4.0, or later
because only DH-CHAP authentication is supported.
For a nonsecure fabric, the hardware and firmware compatibility is described in
Table 59 Hardware and firmware compatibility for nonsecure fabrics
