Programming the IBTrainer Packet Handling Concept
1-4 CATC IBTrainer InfiniBand Exerciser API Reference
In order to handle packets you need to register a packet handler with
the generator class. This involves deriving a class from the class
IGCPacketHandler
and writing the two methods CheckPacket() and
HandlePacket()
. These exist as purely virtual methods in
IGCPacketHandler
. CheckPacket() gets called to determine whether the
packet handler should deal with the packet. Having done this, the
function returns. Subsequently, the base class IGCPacketHandler
manages the call to HandlePacket().
An additional class derived from IGCPacketHandler is included with the
product:
• IGCPacketHandlerTcl provides a class that can handle tcl scripts. This
allows a tcl script to handle incoming packets, simplifying this task.
Subnet management is implemented as an SMA (subnet management
agent), programmed as a tcl script (refer to
“TCL Interface” on page 1-9 ).
