9.3.2 Configuring Local MAC Swap Loopback

A local MAC swap loopback test checks connectivity and performance of the network between
a tester and a tested switch, and performance of the tested switch.
Context
Before performing a local 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 local swap-mac source-mac source-mac-address dest-mac dest-mac-address
vlan vlan-id [ inner-vlan inner-vlan-id ] interface interface-type interface-
number [ timeout { time-value | none } ]
