Measuring
service
disruption time
You can use two units in an end-to-end configuration to
measure the service disruption time resulting from a switch in
service to a protect line. The traffic originating unit must
transmit a constant rate of traffic to obtain accurate measure-
ments.
Monitoring
layer 2 MiM
traffic
Use the MiM Traffic Mon /Thru application whenever you want
to analyze received traffic. When you configure your test, you
can specify settings that indicate the expected received
payload and determine which frames will pass through the
receive filter and be counted in the test result categories for
filtered layer 2 traffic. The settings may also impact other
results.
For detailed instructions, see “Monitoring Ethernet traffic” on
page 93 .
NOTE:
If you are testing from an optical interface, you must turn
the laser on using the associated button to pass the signal
through the unit’s transmitter.
