by default when using ﬁrmware 05.01.00-24 or greater and cannot be disabled. All

HP-approved host bus adapters (HBAs) limit access to devices within their zones, so you

will not see a change in fabric behavior unless you are using nonstandard HBAs. Hard

zoning improves security against intruders that load nonstandard HBA drivers.

Hard zoning is compatible with legacy zone deﬁnitions, including World Wide Nam e

(WWN) and por t 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, m odify your do cumentation, 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 zo nes, 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. D evices will have no

warning when zones change and will not automatically update their zoning inform a tion.

The ability to suppress RSC Ns is disabled (check box is not selected) by default. This

SNMP changes

Firmware 07.00.00-84 supports the following management information base (MIB)

versions on all products:

• Fabric Element MIB: 1.1

• MIB-I I MIB: RFC-1213, non-implemented sections are not included

• FCEOS MIB: 2.0

• SNMP Framework MIB: RFC-2271 (199 7/09/30)

• FA MIB: 3.0

• FA MIB: 3.1

SNMP requests can b e 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.
