Test Duration
Specifies the length of time for which the test should run for the selected port.
Values: 15 minutes, 30 minutes, 1 hour, 24 hours, Continuous
Default: 15 minutes
You can also view the following read-only parameters from this screen:
Pattern Sync
Displays the state of pattern sync during a test. If no test is in progress, "No
Test" is displayed. If a test is active, but the receiver is not in pattern sync,
"No Sync" is displayed. If the receiver is in pattern sync, "In Sync" is
displayed.
Elapsed Time
Displays the time elapsed since a timed test began or, if completed, the total
test time.
Bit Errors
Displays the total number of bit errors detected since the test began or since
error statistics were cleared.
Errored Seconds
Displays the number of asynchronous errored seconds that have been detected
since the test began or since error statistics were last cleared.
%EFS
Displays the percentage of time the test ran error-free. This ratio is derived
from the number of error free seconds divided by the number of seconds
accumulated in Elapsed Time.
Loop Table
The types of tests available for you to choose from depend on the currently
selected interface. For the Network interface, the Loop table provided near the
bottom of the Test Details screen lets you specify the type of Loop test to be
performed.
Values: No Test (Loop Down), payload loopback (PLB), line loopback
Default: No Test (Loop Down)
Bit Errors
Displays the total number of bit errors detected since the test began or since
error statistics were cleared.
Errored Seconds
Displays the number of asynchronous errored seconds that have been detected
since the test began or since error statistics were last cleared.
% EFS
Displays the percentage of time the test ran error-free. This ratio is derived
from the number of error free seconds divided by the number of seconds
accumulated in Elapsed Time.
The Test Details screen provides the following user-activated buttons:
