Introduction This document discusses the details on merging fabrics based on C-series and B-series Fibre Channel switches into a single, standards-based, interoperable fabric. This document also provides information on: • Supported configurations • Expected behavior • Exceptions in the interoperability mode.
C-series merge preparation Step 1: Verify switch firmware versions, page 6 Step 2: Verify switch/fabric default settings, page 7 Step 3: Verify the fabric operating mode, page 7 Step 4: Verify and configure switch domain IDs, page 8 Step 5: Verify zoning configuration, page 8 B-series configuration steps The following steps provide information about verifying and configuring B-series switches for interoperability with a C-series SAN fabric.

Step 4: Verify and configure switch domain IDs Assign a domain ID in the range of 97–127 (0x61–0x7F). There is a maximum of 31 switches allowed in the fabric while in interoperability mode. In the MDS the default is to request an ID from the principal switch. If the preferred keyword is used, the MDS requests a specific ID, but still join the fabric if the principal switch assigns a different ID.
• Any character other than the first character must be either an upper case (A–Z) or lower case (a–z) letter, a number (0–9) or an underscore symbol (_). Configure zones using port WWNs In interoperability mode, all zone members must be defined using port WWNs. Defining them any other way is not supported. Zones cannot be defined using Fibre Channel port addresses or domain and port combinations. If there are any zones not defined with the port WWN, you must redefine them.

Interoperability mode behavior summary by switch type This section provides information about interoperability mode behavior the switches. C-series The MDS series of switches are limited in the following areas when interoperating with non-MDS switches: • Interop mode only affects the specified VSAN. The MDS-9000 can operate with full functionality in other non-interop mode VSANS.
B-series The following is a summary of interoperability mode behavior on B-series switches. • The Msplmgmtdeactivate command must be run prior to connecting it to any C-series, or else the fabric will be segmented. • Zoning can only be defined with port WWNs. Port numbers and NWWNs are not valid fields to zone by. • To manage zoning administration from a B-series switch, all B-series must be interconnected to facilitate the forwarding of the inactive zone configuration also.

NOTE: Cisco NPV mode can be supported with Brocade fabric configured in interopmode or Native mode. If the MDS9124e NPV is connected to an external fabric comprising of only Brocade switches, use Brocade Native mode only. If the MDS 9124e NPV is connected to an external fabric with a mix of Brocade and Cisco switches, then Brocade (and Cisco) switches must be set to interopmode 1. • Brocade AG mode is supported with FOS-OS 5.2.1b or later.
