Admin Domain considerations for Traffic Isolation Zoning
If you implement Admin Domains and TI zones, you should keep the following points in mind:
• 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.
Virtual Fabrics considerations for Traffic Isolation Zoning
This section describes how TI zones work with Virtual Fabrics. See
267 for information about the Virtual Fabrics feature, including logical switches and logical fabrics.
TI zones can be created in a logical fabric like in regular fabrics, with the following exceptions:
• 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.
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.
shows an initiator and target in a logical fabric (FID1). The dotted line indicates a dedicated
path between initiator and target. The dedicated path passes through the base fabric over an XISL.
(The figure shows only physical ISLs, not logical ISLs.) To create the TI zones for this dedicated path,
you must create a TI zone in the logical fabric (FID 1) and one in the base fabric.
