Cascade Zoning
Sanbox Switch chassis support fabric-wide zones for all zone types. Broadcast
Zones and Name Server Zones require no special consideration in a cascade fabric.
That is, you may assign these zones on a user-port-by-user-port basis and T_Ports
are not zoned.
Hard Zones, however, require zoned T_Port interconnections between chassis
which contain ports in the same Hard Zone. That is, if a particular Hard Zone is
distributed across chassis boundaries, each piece of that Hard Zone and its inter-
connecting T_Ports must be assigned to the same Hard Zone number. This makes
interconnections between pieces of the same Hard Zone much like the interconnec-
tion of chassis.
MKII Compatibility
SANbox fabrics do not support MKII chassis in cascade topologies.
NOTE:
Also, remember that mixing of topologies is not allowed. If the topology of the
chassis is Cascade, then the interconnection of the Hard Zones must also be
accomplished in Cascade topology.
