Supported configurations for Traffic Isolation Zoning 12
For example, in Figure 43, 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.

Supported configurations for Traffic Isolation Zoning

Note the following configuration rules for TI zones:
TI Zoning is supported in Brocade Native Mode (interopmode 0) and in a mixed fabric (that is, a
fabric with Fabric OS and M-EOS switches) operating in interopmode 2.
TI Zoning is not supported in fabrics configured in Open Fabric Mode (interopmode 3).
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.
For the FC8-64 blade in the Brocade DCX, ports 48–63 can be in a TI zone only if all switches
in that TI zone are running Fabric OS v6.4.0 or later. Ports 48–63 can still be in a failover path
for TI traffic.
The Brocade DCX-4S does not have this limitation.
TI Zoning 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
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.
TI Zoning 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.
