30 SETTING UP A PROTOCOL ANALYZER ON YOUR
CANOPY NETWORK
Selection of protocol analyzer software and location for a protocol analyzer depend on
both the network topology and the type of traffic to capture. However, the examples in
this section are based on free-of-charge Ethereal software, which is available at
http://ethereal.com/
The equipment required to set up a protocol analyzer includes:
◦ 1 hub
◦ 1 laptop computer with protocol analyzer software installed
◦ 2 straight-through Ethernet cables
◦ 1 Canopy power converter (ACPS110)
30.1 ANALYZING TRAFFIC AT AN SM
The IP address of the protocol analyzer laptop computer must match the IP addressing
scheme of the SM. If the SM has DHCP enabled, then configure the laptop computer to
automatically obtain an address. If DHCP is not enabled, then ensure that the laptop
computer is configured with a static IP address in the same subnet as the SM.
The configuration for analyzing traffic at an SM is shown in Figure 134.
