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.

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
