Some IP addresses must be avoided If you use HAFM to manage other M-Series Fabric directors and edge switches, when you select IP addresses for edge switches, directors, and for the HAFM appliance, do not use IP addresses in the following range: 192.168.0.0 through 192.168.0.255-This subnet is used internally to the HAFM appliance. Using an IP address in this range causes the call-home feature to function incorrectly. Hard zoning Hard zoning is a security enhancement introduced in firmware 05.01.00-24 that prevents ports from accessing devices outside their zones. Hard zoning is enabled 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 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 07.01.02-4 supports the following management information base (MIB) versions on all products: • Fabric Element MIB: 1.1 • MIB-II MIB: RFC-1213, non-implemented sections are not included Director release notes 17

Some IP addresses must be avoided
If you use HAFM to manage other M-Series Fabric directors and edge switches, when
you select IP addresses for edge switches, directors, and for the HAFM appliance, do
not use IP addresses in the following range:
192.168.0.0 through 192.168.0.255—This subnet is used internally to the HAFM
appliance. Using an IP address in this range causes the call-home feature to function
incorrectly.
Hard zoning
Hard zoning is a security enhancement introduced in
fi
rmware 05.01.00-24 that
prevents ports from accessing devices outside their zones. Hard zoning is enabled
by default when using
fi
rmware 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 de
fi
nitions, 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
Noti
fi
cation (RSCN) is sent to all devices in the fabric. With
fi
rmware 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 Con
fi
gure Switch Parameters dialog box.
This feature signi
fi
cantly 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 con
fi
gured through HAFM, EWS, and CLI.
