Virtual Fabric considerations for Traffic Isolation Zoning

This section describes how TI zones work with Virtual Fabrics. See

fabrics.
TI zones can be created in a logical fabric like in regular fabrics, with the following exceptions:
•
•
The TI zone in the logical fabric includes the extended XISL (XISL) port numbers, as well as the
F_Ports and ISLs in the logical fabric.
The TI zone in the base fabric reserves XISLs for a particular logical fabric. The base fabric TI zone
should also include ISLs that belong to logical switches participating in the logical fabric.

dedicated path, you must create a TI zone in the logical fabric (FID 1) and one in the base fabric.

TI zones that have members with port index greater than 511 are not supported with Fabric OS
versions earlier than v6.4.0. If such a TI zone and Fabric OS version combination is detected, a
warning is issued. These configurations are not prevented, but their behavior is unpredictable.
When you merge two switches, if there is an effective configuration on the switches and TI
zones are present on either switch, the TI zones are not automatically activated after the
merge. Check the TI zone enabled status using the zone
Enabled status does not match across switches, issue the cfgEnable command.
Use care when creating TI zones on ICL ports in topologies that span more than two switches
connected with ICLs. If a user-defined TI zone breaks the ICL connectivity requirements, a
RASlog message is generated to notify you of this error condition.
TI zones are applicable only in AD0, and the E_Ports that are members of a TI zone must be in
the AD0 device list. Because TI zones must use D,I notation, the AD0 device list must be
declared using D,I notation for ports that are to be used in TI zones.
A port used in a TI zone should not be a member of multiple Admin Domains.
Use care if defining TI zones with ports that are shared across Admin Domains because of the
limitation that a given port can appear in only one TI zone.
Best practice: Do not use ports that are shared across Admin Domains in a TI zone.

The disable failover option is not supported in logical fabrics that use XISLs.
Although logical switches that use XISLs allow the creation of a TI zone with failover disabled,
this is not a supported configuration. Base switches do not allow the creation of a TI zone with
failover disabled.
To create a TI zone for a logical fabric that uses XISLs, you must create two TI zones: one in the
logical fabric and one in the base fabric. The combination of TI zones in the base fabric and
logical fabric sets the path through the base fabric for logical switches.
