18 Supported configurations for Traffic Isolation Routing For example, in Figure 56, the TI zone was configured incorrectly and E_Port "3,9" was erroneously omitted from the zone. The domain 3 switch assumes that traffic coming from E_Port 9 is not part of the TI zone and so that traffic is routed to E_Port 11 instead of E_Port 12, if failover is enabled. If failover is disabled, the route is broken and traffic stops. Domain 1 Domain 3 8 1 9 2 9 10 12 11 = Dedicated path = Ports in the TI zone FIGURE 56 TI zone misconfiguration 87 6 5 Domain 4 Supported configurations for Traffic Isolation Routing Note the following configuration rules for TI zones: • Traffic Isolation Routing is supported only on Brocade 200E, 300, 4100, 4900, 5000, 5100, 5300, 5410, 5424, 5450, 5480, 7500, 7500E, 7600 switches, the Brocade 48000 and Brocade DCX platforms, all configured in Brocade Native Mode (interopmode 0). • Ports in a TI zone must belong to switches that run Fabric OS v6.0.0 or later. For TI over FCR zones, ports must belong to switches that run Fabric OS v6.1.0 or later. • Traffic Isolation Routing has limited support for FICON FCIP in McDATA Fabric Mode (interopmode 2), in the following configuration only: - Brocade 7500 with E_Port connections to an M-switch and VE_Port connections to another Brocade 7500. - Devices attached to M-switch only. Following is a sample configuration: Devices - M-switch - Brocade 7500 - Brocade 7500 - M-switch - Devices • Fabric OS 6.1.0 or later supports Traffic Isolation Routing in a mixed fabric (that is, a fabric with Fabric OS and M-EOS switches) operating in interopmode 2. Traffic Isolation Routing is not supported in fabrics configured in Open Fabric Mode (interopmode 3). • In interopmode 2, a zone member for a TI zone is limited to a port index of 255 or less. • VE_Ports are supported in TI zones. • Traffic Isolation Routing is not supported in fabrics with switches running firmware versions earlier than Fabric OS v6.0.0. However, the existence of a TI zone in such a fabric is backward-compatible and does not disrupt fabric operation in switches running earlier firmware versions. 402 Fabric OS Administrator's Guide 53-1001336-01
