Classifier-Based Software Configuration
Zone Classes
Zone Classes
Zone classes are used in conjunction with a technology called Transparent
Mode. Both zone classes and Transparent Mode are supported on the HP
5400zl and 8200zl Switch Series when:
■ The switch is running software version K.14.58 and above
■ An HP AllianceONE Extended Services zl Module is installed in the switch
Transparent Mode enables the HP 5400zl or 8200zl switch to intercept packets
that match certain criteria and redirect them to an application that is running
on an HP AllianceONE Extended Services zl Module. In effect, Transparent
Mode allows that application to be in the path of packet flow. (Applications
that run on AllianceONE Extended Services zl Modules are referred to as
“ONE applications.”)
Packet interception differs from port mirroring. With port mirroring, the
switch copies the packets being sent from a particular source port to a
particular destination port and sends these packets to a mirror port. The
original packets continue to be sent from the source port to the destination
port without interruption.
With packet interception, on the other hand, the switch does not copy packets
to another port. Instead the switch actually intercepts the packets and for-
wards them to the ONE application. The ONE application can then make
decisions based upon those packets and control or modify the packets before
they are delivered to their final destination.
After intercepting and redirecting the packets to the ONE application, the HP
5400zl or 8200zl switch does not perform any further action on the intercepted
packets.
Because a ONE application is required to act on the intercepted packets,
Transparent Mode is available only when an HP AllianceONE Extended
Services zl Module is installed in the zl switch. In addition, the switch must
also be running software version K.14.58 or above.)
Note Check the release notes for the switch software you are using to ensure it
supports the ONE application that is running on your AllianceONE Extended
Services zl Module.
