Use the Troubleshooting Mode
1. Click Enable to begin working in the troubleshooting
mode.
2. In the Packet Logging frame, select the Packet Logging
Time from the available selections (10 seconds, 30
seconds, 60 seconds). This time is the interval during
which the server captures packets in real time, ranging
from the moment the command is executed until the
designated point of time in the future.
3. At the Capture Device field, the default listening device
for the operation mode displays. If necessary, make a
selection from the pull-down menu that corresponds to
the operation mode used on the network—”LAN2” or
“LAN1”.
4. At the Promiscuous Mode field, the default choice (“on”
or “off”) displays, based on the operation mode that was
selected. The promiscuous mode is a mode of operation
in which each data packet that is sent will be received
and read by the Network Interface Card (NIC).
5. If necessary, click the appropriate radio button to indicate
whether to turn the promiscuous mode on or off. If “on” is
selected, the R3000 will watch all network traffic as in the
invisible mode. If “off” is selected, the R3000 will only
capture packets sent to or from the R3000.
6. At the Capture String/Rule field, select the type of
packets to be captured: Transmission Control Protocol
(TCP); Address Resolution Protocol (ARP); packets
destined to a specified port (80, 443, 81); packets
destined to the R3000; packets sent to or from port 20 or
21; or packets sent to the Virtual IP address’s port 137 or
139.
7. Click Execute to display results in the Result list box.
