Context
A loopback test deteriorates network performance. If a large number of test packets are sent,
bandwidth of other services is occupied. Therefore, disable the MAC swap loopback function
immediately after the loopback test is complete.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
MAC swap loopback tests cannot be performed on an Eth-Trunk interface or its member
interfaces.
Step 3 Run:
loopback swap-mac stop
The MAC swap loopback function is disabled.
This is a one-time command and is not saved in the configuration file.
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.
