Network Tools
Maximum Hop Count The maximum number of routers to traverse while tracing out the route.
SNMP Query
This tool uses SNMP to retrieve the following information from the device. This information is usually provided by IT services.
•MIB II System Group
•System description
•Up time
•Contact
•System name
•Location
Locate Switch Port
This tool is used to determine the switch port to which a device is connected. SNMP is used to look for switches in the network. Each of these switches are probed to see if the device shows up in the switch’s tables. All of the switch ports which are mapped to the devices MAC address are displayed. There is no order to the list for multiple results, so you cannot interpret the results as a direct path.
Performance Tests
The Performance Tests tool is used to verify the performance of a network between two network points. These tests are IP and MAC loopback tests, RFC 2544 throughput ,latency, frame loss rate and back to back tests. For details on each test, go to “Performance Tests” on page 53. Some points to note are:
•All loopback and RFC 2544 tests require a second FrameScope as a slave device.
•The MAC loopback test only works within the subnet (does not work across routers).
Traffic Generation
A hardware based traffic generation tool is provided to enable network testing under heavily loaded conditions.
