nameserver zones are possible within one hard zone. Overlapping nameserver zones are not supported. In a hard zone containing F_Ports and TL_Ports, nameserver zones must be created if you need more than one zone.

SL Zones

SL zones on the switch allow the division of the Fabric into zones that define the ports that can communicate with each other. A particular port may be placed in only one SL zone (no overlapping SL zones). If hard zones are enabled, SL zones do not communicate across defined hard zone boundaries. In a hard zone consisting of SL ports, SL zones must be created if you need more than one zone.

The switch does not prevent the user from creating an SL zone spanning more than one switch; however, the current release of the Sun StorEdge FC switch requires the user not to extend the SL zone beyond one switch.

Zoning Rules

■Only port-based zoning is supported.

■Zones are non-overlapping, except in cascading switches, in which ISL can be shared across nameserver zones that exist in the same hard zone.

■Nameserver zones and SL zones must be in separate hard zones.

■A minimum of one switch port per zone is supported.

You can have a maximum of 16 hard zones and 16 nameserver or SL zones on a 16-port switch. In a cascaded configuration (16-port to 16-port), you can configure a maximum of 16 hard zones and 30 nameserver or SL zones.

Cascading Rules

■Hub-to-switch connectivity is not supported

■Maximum of two switches cascaded in series
