Zone management in interoperable fabrics 14 Zone management in interoperable fabrics McDATA Fabric and McDATA Open Fabric modes support zone activation using an M-series management tool such as such as Data Center Fabric Manager (DCFM) or Web Tools. You can only launch one zoning management tool at a time. The Defined Database is where special zones, such as, Frame Redirection and Traffic Isolation zones, reside on Fabric OS switches. When joining switches in a mixed fabric, the Defined Database does not merge with the M-series switch zoning databases. McDATA Fabric and McDATA Open Fabric modes support zone activation, which allows fabric-wide and stand-alone zone configurations, for Traffic Isolation and Frame Redirection only. You can create new zones, modify existing zones, and then save these configurations to the Defined Database on the local Fabric OS switch. This allows the distribution of the Defined Database to all Fabric OS switches in McDATA Fabric mode in the case where the Fabric OS switches are used to control zone management for TI and FR zones. When joining switches in a mixed fabric, the Defined Database does not merge with M-series switches. Zoning restrictions Before creating or configuring a zone, note the following zoning characteristics and requirements for McDATA Fabric and McDATA Open Fabric modes: • There are four zoning limits that must be met: - Maximum Number of Zones - 2047 (+1 for the default zone) - Maximum Number of Members per Zone - 4096 - Maximum Number of Unique Zone Members per Zone Set - 4096 - Maximum Zone Set Definition Size - 2048 Kb • IM2 and IM3 support LSAN zones to export devices across an FCR backbone. The FCR backbone cannot be in IM2 or IM3, it must be in IM0. • Only zoning by port WWN is allowed in IM3 only; you must use the port WWN of the device, such as 10:00:00:00:c9:28:c7:c6. • Zone members specified by node WWN are ignored. • Zone database is managed on the DCFM management server. • Fabric OS switches connected to M-EOS switches receive the effective configuration when a zone merge occurs. (M-EOS only has an effective zone configuration and discards the defined zone configuration when it sends merge information to the Fabric OS switch.) However, a zone update sends the defined and effective configuration to all switches in the fabric. • When no zoning configuration is in effect, and without default zoning enabled on an M-EOS switch, by default, all ports are isolated and traffic is not permitted. This is unlike Brocade behavior with Brocade Native mode enabled (and all data traffic is enabled). If the default zone is disabled and there is no active configuration, then no device can communicate with any other device in the fabric if zoning is disabled on a Fabric OS switch. • Defining zones in the effective configuration or the Defined Database is allowed in IM2 only. • Legacy McDATA switches do not support the Defined Database or merge propagation. • Zoning using domain,port notation is allowed. Zone configurations that use either physical port numbers or port IDs are supported. Fabric OS Administrator's Guide 299 53-1001336-01
