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 Handle
Packet() .
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 ).
