4.5 Network Analysis Tools
4.5.1 Overview
Network analysis is a combination of several network tools, including Ethernet Sniff, Subnet List,
and Ping test.
4.5.2 Network Tools Test Screen and Operation
On the Main Menu, highlight “Network Tools” (press the MODE button to enter the Main Menu if
you are not already on it; press the Up or Down Arrow Keys to highlight it). Once the “Network
Tools” option is highlighted, press the Right Arrow Key to select the test. (See next page for a
diagram of each feature on this screen.)
VERIFY & UPDATE IP, SUBNET, GATEWAY, AND DESTINATION:
The list on the left side of the Network Tools screen will display the Tester’s current IP,
Subnet Mask, Gateway, DNS, and Destination settings. To change these settings, select
SET to access the IP Settings screen, then use the Arrow Keys and Flip Keyboard to
make changes. Select Iris+ when you are done to confirm the changes and return to the
Network Tools screen.
ETHERNET SNIFF:
While you are on the Network Tools screen, press Focus+ to start the Sniff test. Once
Ethernet Sniff is started, the Tester will listen to the network, waiting for broadcast data,
detecting MAC and IP addresses. Unlisted new MAC and IP addresses will be added to the
list. Press Focus+ again to end the test.
The format of the list is XX-XX-XX-XX-XX-XX I.I.I.I; where XX is a MAC address in HEX,
and I is an IP address displayed in decimal.
Most network devices broadcast data packets periodically, identifying their presence. The
Sniff function will detect this data and discover unknown network devices. The sniff function
is detecting broadcasting data packets, so devices of any subnet and any kind can be found.
When connecting to an unknown device with an unknown IP address, first try using the
DHCP server to distribute IP to the device. If the device is not requesting an IP address,
then use this Sniff function to detect the device.
Detecting a device using the Sniff function may take 3 to 60 seconds, depending on the
device broadcasting frequency, and the Tester will not detect a device if it remains silent.
NOTE — The sniff function does not detect uni-cast (point-to-point) packets.
