HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 15

Hard zoning is compatible with legacy zone definitions, including World Wide
Name (WWN) and port zoning. You can use your existing zones and zone sets
without any changes. There are no changes to the zoning interfaces, so you do not
need to modify your zone management practice, modify your documentation, or
retrain Storage Area Network (SAN) administrators.
Hard zoning controls access at the ingress port. When a port attempts to send a
frame to a destination outside its zones, the frame is blocked. A Class 2 frame is
fabric rejected, and a Class 3 frame is dropped.
Zoning change RSCN control
Normally, when a zone set is activated, a fabric format domain Register State
Change Notification (RSCN) is sent to all devices in the fabric. With firmware
05.00.00 or later, you can disable these RSCNs from being sent. This is done
using the Suppress RSCNs on zone set activations check box on the Configure
Switch Parameters dialog box.
This feature significantly changes the normal behavior of the fabric. Devices will
have no warning when zones change and will not automatically update their
zoning information. The ability to suppress RSCNs is disabled (check box is not
selected) by default. This feature can be configured through HAFM, EWS, and
CLI.
SNMP changes
Firmware 06.02.00-22 supports the following management information base
(MIB) versions on all products:
SNMP requests can be received in either 3.0 or 3.1 of the Fibre Alliance (FA)
MIB, and the switch responds in the same version. The switch can also be
configured to use a specific version for traps generated by the switch.
