You can set a loopback for an Ethernet interface by using the U2000 Web LCT. The Ethernet interface loopback is a common fault location method used to test and maintain the Ethernet board. The Ethernet interface loopback is used to test the fiber connections on the Ethernet board.
Context
You can perform an inloop for an Ethernet interface by using the U2000 Web LCT.
NOTICE: As a loopback interrupts services, it is only used for fault location and must be released after the fault is removed.
Procedure
- In the NE Explorer, select a board and choose from the Function Tree.
- Select External Port and click the Basic Attributes tab.
- Select an Ethernet interface from the list and double-click MAC Loopback or PHY Loopback to choose the loopback mode.
- Click Apply and the U2000 Web LCT prompts that this operation may interrupt the service.
- Click OK. A prompt appears telling you that the operation was successful. Click Close.
