9.4.2 Configuring Remote MAC Swap Loopback

A remote MAC swap loopback test checks connectivity and performance of the network between
a tester and a tested switch but does not check performance of the tested switch.
Context
Before performing a remote MAC swap loopback test, configure the source MAC address,
destination MAC address, and VLAN ID of test packets on the S3700. Only the packets with
the specified source MAC address, destination MAC address, and VLAN ID are looped back.
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 remote swap-mac source-mac source-mac-address dest-mac dest-mac-address
vlan vlan-id [ inner-vlan inner-vlan-id ] [ timeout { time-value | none } ]
Remote MAC swap loopback is configured.
A remote MAC swap loopback test modifies only Ethernet frames matching the MAC swap
loopback configuration on an interface, and other Ethernet frames can still be forwarded on the
interface. However, if a large number of test packets are sent, test packets occupy bandwidth of
other services on the interface.
If single VLAN tag is configured on the S3700, the test packets cannot be double-tagged.

Context
A loopback test deteriorates network performance. If a large number of test packets are sent,
bandwidth of other services is occupied. To ensure network performance, enable the MAC swap
