Network Testing with the FrameScope Pro 2

Performance Tests

Performing a MAC or IP Loopback

N O TE	The MAC loopback test only works within the subnet (does not
	work across routers).

The master or target FrameScope sends periodic MAC-level or IP-level messages to the slave FrameScope with user-defined periodic interval. The slave FrameScope echoes back each of these messages. The FrameScope will record the number of transmitted, received and error frames, the current, average, minimum and maximum delays of frames.

To perform the tests, see the following steps:

1From the Performance Tests menu, select MAC Loopback or IP

Loopback

2There are two options to search for the slave FrameScope:

Option 1: If you do not know the MAC or IP address/name of the slave FrameScope, select Search for FrameScope.

Option 2: For MAC Loopback, un check the Search for FrameScope check box and enter the MAC address of the slave FrameScope. For IP Loopback, enter the IP

address or name of the slave FrameScope.

3In the MAC or IP Loopback menu, press Start or press the OK button to begin the test.

The FrameScope will search the other FrameScope (which will be acting as slave) on the network and then report back the link results.
