LAN Card on STRM
500 II
The Flow Collector collects data from devices and various live and recorded feeds
such as network taps, span/mirror ports, NetFlow, and STRM flow logs. The Flow
Collector then groups related individual packets into a flow. A flow starts when the Flow
Collector detects the first packet with a unique source IP address, destination IP
address, source port, and destination port as well as other specific protocol options,
which may determine the start of a communication. Each additional packet is
evaluated and counts of bytes and packets are added to the statistical counters in the
flow record. At the end of an interval a status record of the flow is sent to a Flow
Processor and statistical counters for the flow are reset. A flow ends when no activity
for the flow is seen within the configured period of time. Flow reporting generates
records of all the active or expired flows during a specified period of time. STRM
defines these flows as a communication sessionbetween two pairs of unique IP
address/ports that use the same protocol. If the protocol does not support port-based
connections, STRM combines all packets between the two hosts into a single flow
record. However, a Flow Collector does not record flows until a connection is made to
another STRM component and data is retrieved.
To install the Flow Collector 4-port LAN card on an STRM 500 II unit:
Step 1
Power down the STRM 500 II unit.
Step 2
Unscrew the two thumbscrews on the right-most blank IO module and remove the
dummy tray.
Step 3
Insert the 4-port 1GB LAN module firmly and screw in the two thumbscrews.

Step 4
Power on the STRM 500 II unit and watch it boot on the serial console.
Step 5
Verify the link and activity LED on the new 4-port 1GB LAN module light up when
connecting the ports to your Ethernet switch with a standard CAT5e or CAT6 LAN
cable.
Step 6
Login to the admin console and you should now see 4 more Ethernet interfaces appear
as eth4-eth7. The 4-port are labeled 0, 1, 2 and 3 and should map to Ethernet
interfaces as follows:
- 0 = eth7
- 1 = eth6
- 2 = eth5
