IXP2400 Network Connections
After you have configured the packet simulation with devices and ports and created or imported
data streams, you need to specify the connections to the media/switch fabric for each chip in your
project.
1. On the
Simulation
menu, click
System Configuration
, then click the
Network Connections
tab.
The
Network Connections
property page appears. The page is divided into two sections:
Receive side connection
and
Transmit side connection.
2. Select the chip to which you want to make connections in the
Specify connections for chip
combo box.
3. When you have finished click
OK
.
If
No Connection
is selected, then the simulation runs without anything connected to that side of
the MSF.
In multi-chip projects, the receive side can be connected to the transmit side of another chip in the
project by selecting
Connect to transmit side of chip
. The user must select which chip and what
protocol to use for the connection. For the IXP2400, the protocols are POS3 and CSIX. Similarly,
the transmit side can be connected to the receive side of another chip in the project by selecting
Connect to receive side of chip
.
To connect a device to either side, the user selects
Connect to device
then selects the desired
device in the combo box. Note that because a device can only be connected once, if it is selected
for a connection then the Workbench removes it as a choice for all other connections.
