Table 6-1: Line Test Type for Each Frame Loopback Point

Frame Loopback Point	Line Test Type	Failure That Can Be Identified

System	Intra-module loopback test	System (excluding RJ45 connectors or transceiver)

Loop connector	Loop connector loopback test	System (including RJ45 connectors and transceiver)

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."

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]
>	test interfaces gigabitethernet 1/1 internal [Enter]
