This document also provides information • Supported configurations • Expected behavior • Exceptions in the interoperability mode.

Page 4: Step 1: Verify Switch Firmware Versions
The following steps provide information about verifying and configuring B-series switches for interoperability with a C-series SAN fabric. Although Fabric Manager, the embedded Web Tools, or the CLI (through Telnet) can be used to configure the switches, the following steps use CLI. -

(4). Step 4: Verify and configure fabric operating mode For B-series switches the interopmode 1 must be enabled before merging with C-series switches. This command enables interopmode on individual switches only and therefore, must be executed on each B-series switch in the fabric. -

C-series configuration steps This section provides information about how to configure C-series switches for interoperability. Although you can use either the Fabric Manager or the CLI, the following steps use CLI (Telnet).

- Page 8 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.

E_Ports from both sides can be connected to merge them. The interop fabric reconfigures and merges into a single fabric. To verify the fabric has merged properly, run the following commands on both the B-series and C-series switches and ensure they are no segmentations or other errors. - Page 10 Be sure to plan accordingly when changing the domain ID. • Non-Disruptive: This event is limited to the VSAN on C-series where the change is taking place. The MDS switch can perform this action, as the domain manager process for this VSAN is re- started and not the entire switch.

Merging zones-examples This example depicts the creation of three zones (vz1, vz2, and vz3) on one of the C-series switches; and then the verification that these zones propagate to all the C-series and B-series switches in the interoperating fabric.

B-series switches Use Telnet on B-series switches to verify that the zoning information has propagated properly. On B-series you will see the active configuration as well as any defined configurations that are not part of active configuration.
- Page 14 The first step is to clear the zoning configuration. If the switch is part of the fabric, all switches will have no zoning in effect after the cfgClear command is issued.

Page 16: Supported Configuration Rules And Guidelines
If you notice longer fabric reconfiguration times, select one of the B-series switches as the principal switch. • If SAN boot is required and the HBA is connected to a B-series switch, lock the switch port as a G_Port using the portcfggport command. This prevents the HBA from appearing in loop topo- logy. - Page 17 Brocade AG interoperability with Cisco is supported with Emulex HBAs only (no QLogic HBA support). • Continuous Access EVA and Continuous Access XP storage systems are supported in a C-series and B-series interoperable heterogeneous switch fabric configurations. See EVA and XP firmware versions.
