(2) Checking frame loopback at a loop connector

Execute the loop connector loopback test to check frame loopback at a loop connector. Before performing loop connector loopback test or connecting the loop connector, use the inactivate command to set the port in the inactive state. To end the test, restore the connection and use the activate command to change the port from inactive to active. In this test, test frame loops back at a loop connector connected to this system to check for the NIF failure [IP8800/S6700] [IP8800/S6600] [IP8800/S6300] and system failure (including RJ45 connector and transceivers)

[IP8800/S3600] [IP8800/S2400]. This test is available for all line types.

For each line type, remove the cable of the test target port number and connect the loop connector for each line type to execute the test. Note that, if the loop connector is not connected or the appropriate loop connector for the port is not connected, the test cannot be successfully executed.

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 after the cable is removed and the loop connector for each line type is connected 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]

(Connect the loop connector to the corresponding port.)

> test interfaces gigabitethernet 1/1 connector [Enter]

(Wait about 1 minute.)

> no test interfaces gigabitethernet 1/1 [Enter]

(Remove the loop connector from the corresponding port and restore the connection.)

> activate gigabitethernet 1/1 [Enter]

IP8800/S3600 and IP8800/S2400

A case of test conducted on Port 1 of NIF 0 at a transmission interval of one second after the cable is removed and the loop connector for each line type is connected 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 0/1 [Enter]

(Connect the loop connector to the corresponding port.)

> test interfaces gigabitethernet 0/1 connector [Enter]

(Wait about 1 minute.)
