Ports
Zones
Zoning allows the user to divide the switch ports into zones for more efficient and
secure communication among functionally grouped nodes. There are several types
of zones. No port can be in all zone types simultaneously. F_Ports and TL_Ports
have to be in nameserver zones, and SL zones have to be in SL zones. Nameserver
zones and SL zones must also be in separate hard zones.

zones and SL zones must also be in separate hard zones.
Hard Zones
Hard zones isolate ports through internal switch hardware; no communication
across hard zone boundaries is possible. Hard zoning is desirable for security and
resource dedication because it provides a way of isolating a set of ports from other
ports within the Fabric.. Up to sixteen hard zones are possible within a Fabric. A
particular port may be placed in only one hard zone (no overlapping hard zones). If
hard zones are enabled, nameserver zones and SL zones do not communicate across
defined hard zone boundaries. Nameserver zones and SL zones must also be in
separate hard zones.

Nameserver Zones
Nameserverzones allow the division of the Fabric (one or more Switch chassis) into
as many as 256 Fabric-wide zones; each Nameserver zone defines which ports or
devices receive nameserver information. If hard zones are enabled, nameserver
zones do not communicate across defined hard zone boundaries. Up to 16
