Supported configurations for Traffic Isolation Zoning
The following configuration rules apply to TI zones:
• Ports in a TI zone must belong to switches that run Fabric OS v6.0.0 or later. For TI over FCR
zones, all switches and FC routers in both edge and backbone fabrics must be running Fabric OS
v6.1.0 or later.
• For the FC8-64 and FC16-64 blades in the Brocade DCX and DCX 8510-8, 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 and DCX 8510-4 do not have this limitation.
• 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.
Additional configuration rules for enhanced TI zones
Enhanced TI zones (ETIZ) have the following additional configuration rules:
• Enhanced TI zones are supported only if every switch in the fabric is ETIZ capable. A switch is ETIZ
capable if it meets the following qualifications:
‐ The switch must be one of the supported platforms, as listed in Supported hardware and
software.
‐ The switch must be running Fabric OS v6.4.0 or later.
• If the fabric contains a switch running an earlier version of Fabric OS, you cannot create an
enhanced TI zone. You cannot merge a downlevel switch into a fabric containing enhanced TI
zones, and you cannot merge a switch with enhanced TI zones defined into a fabric containing
switches that do not support ETIZ.
• Overlapping TI zones must have the same failover type. That is, both must be either failover
enabled or failover disabled.
NOTE
FC router domains are excluded from the ETIZ platform restrictions. You can create enhanced TI
zones with these switches in the fabric.
Trunking with TI zones
If you implement trunking and TI zones, you should keep the following points in mind:
• To include a trunk group in a TI zone, you must include all ports of the trunk in the TI zone.
• Trunked ISL ports cannot be members of more than one TI zone.
• The zone command includes an option to show TI trunk errors.
