Configuring Zones
90 Embedded Web Server User Guide
When fabrics join through an ISL, adjacent managed products exchange active
zone configurations and determine if the configurations are compatible and can
merge. Zoning configurations are compatible if the active zone names in each
fabric are unique. If there are identical zone names in each fabric, then the zones
must have identical members for the fabrics to join.
If the configurations can merge, the fabrics join. The resulting configuration will
be a single zone set containing zone definitions from each fabric.
If configurations cannot merge, the expansion ports (E_Ports) on each product
become segmented. Segmented E_Ports cannot carry traffic from attached devices
(class 2 or 3 traffic), but can carry management and control traffic (class F traffic)
between managed products.
Rules for Merging Zoned Fabrics
Certain rules are enforced to ensure that zoning is consistent across the fabric.
Table 3 summarizes rules for joining two fabrics through an ISL. The following
terms are used in the table:
■ Not zoned — No zone set is active in the fabric and the default zone is
enabled. In other words, all devices in the fabric are visible to all other
devices in the fabric.
■ Zoned — A zone set is active in the fabric and/or the default zone is disabled.
In this case, devices can discover other devices that are members of the same
zone.
■ Zoning configuration — Combination of the active zone set definition and the
default zone state (enabled or disabled).
