In line tests, the loopback points of frames or data sent for the test differs depending on the type of test specified. The
frame loopback points for each test type is given in the figure below:
frame loopback points for each test type is given in the figure below:
Figure 6-1: Loopback Points of Frames for Each Type of Line Test
Table 6-1: Line Test Type for Each Frame Loopback Point
In addition, executable test types also differ depending on the type of line. For the line types and available test types,
see the manual "Operation Commands."
see the manual "Operation Commands."
The following is an explanation of test methods for each type of test.
(1) Checking frame loopback within system
When checking the frame loopback in the system, perform the intra-module loopback test. Use the inactivate
command to set the port to inactive state before executing the intra-module loopback test. To end the test, use the
activate command to change the port from inactive to active. In this test, test frame loops back in this system to
check for the NIF failure [IP8800/S6700] [IP8800/S6600] [IP8800/S6300] and system failure (excluding RJ45
connector and transceivers) [IP8800/3600] [IP8800/S2400].

This test is available for all line types.
IP8800/S6700, IP8800/S6600, and IP8800/S6300
A case of test conducted on Port 1 of NIF 1 at a transmission interval of one second is shown as a test example.
Execute the test interfaces command and the no test interfaces command in this order from the
operation terminal.
> inactivate gigabitethernet 1/1 [Enter]
Execute the test interfaces command and the no test interfaces command in this order from the
operation terminal.
> inactivate gigabitethernet 1/1 [Enter]
> test interfaces gigabitethernet 1/1 internal [Enter]
(Wait about 1 minute.)
