Loopback Support
The KSZ8873MLL/FLL/RLL provides loopback support for remote diagnostic of failure. In loopback mode, the speed at
both PHY ports needs to be set to 100BASE-TX. Two types of loopback are supported: Far-end Loopback and Near-end
(Remote) Loopback.
Far-End Loopback
Far-end loopback is conducted between the KSZ8873MLL/FLL/RLL’s two PHY ports. The loopback is limited to a few
packages at a time for diagnosis purpose and cannot support large traffic. The loopback path starts at the “Originating.”
PHY port’s receive inputs (RXP/RXM), wraps around at the “l(fā)oopback” PHY port’s PMD/PMA, and ends at the
“Originating” PHY port’s transmit outputs (TXP/TXM).
Bit [0] of registers 29 and 45 is used to enable far-end loopback for ports 1 and 2, respectively. Alternatively, the MII
Management register 0, bit [14] can be used to enable far-end loopback.
The far-end loopback path is illustrated in Figure 13.
