Huawei Quidway S6700 series User Manual

A MAC swap loopback test stops when you disable the MAC swap loopback function or the
loopback test times out. To perform the loopback test again, run the loopback swap-mac
start command.
----End
7.4.5 Checking the Configuration
After configuring the remote MAC swap loopback function, use the following command to
verify the configuration.
Prerequisite
All configurations of remote MAC swap loopback are complete.
Procedure
l Run the display loopback swap-mac information command to view the configuration of
remote MAC swap loopback.
----End
Example
Run the display loopback swap-mac information command to check whether remote MAC
swap loopback is configured correctly. After test packets are sent, run this command to check
the number of received loopback packets.
<Quidway> display loopback swap-mac information

7.5 Configuration Examples
This section provides examples of MAC swap loopback configuration.
7.5.1 Example for Configuring Local MAC Swap Loopback
Networking Requirements
As shown in Figure 7-3, Switch B is an S6700. On Switch B, XGE 0/0/1 is connected to an
Ethernet network, and XGE 0/0/2 is connected to users.
A local MAC swap loopback test needs to be performed on XGE 0/0/2. A tester sends Ethernet
frames to Switch B. After the source and destination MAC addresses of the Ethernet frames are
swapped on XGE 0/0/2, the Ethernet frames are sent back to the tester through XGE 0/0/1. The
tester analyzes connectivity and performance of the Ethernet network and Switch B based on
the received Ethernet frames.
