Specify the reflection mode for the benchmarking test.



(Junos OS ACX Series routers only) Enable rewriting of the MAC address on the reflected frames. You configure which MAC addresses the software should use with the source-mac-address and destination-mac-address configuration statements.


Swap the source and destination MAC addresses in the test frame. This is the default behavior.


In bridge families, when the service type is ELAN, MAC addresses are swapped by default on the reflected frames. When the service type is ELINE , MAC addresses are not swapped by default.


Do not swap the source and destination MAC addresses in the test frame. The frame is returned to the originator without any modification to the MAC addresses.
