Start a Network Trace Manually
1 From the menu bar, click Tools > Capture Network Trace. The
Capture Network Trace screen appears.
2 From the Configuration Options area, select the type of network
trace you want to perform:
• External — configures the trace tool to capture all traffic
between the library and the outside world. As most networks
are now switched, this should not cause any traffic to be
captured from other workstations on the same segment, except
for some broadcast packets.
• Internal — configures the trace tool to capture all traffic
internal on the library backbone. This has to be traffic
originating, or passing through the MCB. Traffic between the
RCU and the PRPs for example will NOT be captured.
• Loopback — a virtual interface on the MCB. This will ONLY
capture traffic which uses this specific interface for daemons
and other processes internally to the MCB.
• All — captures all traffic on all interfaces combined.
3 Enter a value in the Max File Size (MB) field from 0 to 1000MB. The
trace will automatically stop when the value in the Max File Size
field is reached.
