• Wrap-AB - The flow of the primary ring is entering through port A
(primary in) and is wrapped by the MAC, causing the ring to exit
through port A (secondary out). The MAC has also wrapped port B,
causing the flow of the ring to enter through port B (secondary in) and
exit through port B (primary out). The HSIM-F6 MAC Configuration
can read “Wrap-AB” if the HSIM-F6 is in a dual homed
configuration.
