“transmit only” mirror on a port
All the packets transmitted on the port are mirrored on the sniffer port. For example, port 1 is programmed to be
“transmit sniff” and port 3 is programmed to be the “sniffer port”. A packet received on port 2 is destined to port
1 after the internal lookup. The KSZ8893FQL forwards the packet to both port 1 and port 3.
“receive and transmit” mirror on two ports
All the packets received on port A and transmitted on port B are mirrored on the sniffer port. To turn on the
“AND” feature, set register 5 bit [0] to ‘1’. For example, port 1 is programmed to be “receive sniff”, port 2 is
programmed to be “transmit sniff”, and port 3 is programmed to be the “sniffer port”. A packet received on port
1 is destined to port 2 after the internal lookup. The KSZ8893FQL forwards the packet to both port 2 and port 3.
Multiple ports can be selected as “receive sniff” or “transmit sniff”. In addition, any port can be selected as the “sniffer
port”. All these per port features can be selected through registers 17, 33 and 49 for ports 1, 2 and 3, respectively.
IEEE 802.1Q VLAN Support
The KSZ8893FQL supports 16 active VLANs out of the 4096 possible VLANs specified in the IEEE 802.1Q
specification. KSZ8893FQL provides a 16-entry VLAN Table, which converts the 12-bits VLAN ID (VID) to the 4-bits
Filter ID (FID) for address lookup. If a non-tagged or null-VID-tagged packet is received, the ingress port default VID is
used for look-up. In VLAN mode, the look-up process starts with VLAN Table lookup to determine whether the VID is
valid. If the VID is not valid, the packet is dropped and its address is not learned. If the VID is valid, the FID is retrieved
for further lookup. The FID + Destination Address (FID+DA) are used to determine the destination port. The FID +
Source Address (FID+SA) are used for address learning.

Advanced VLAN features, such as “Ingress VLAN filtering” and “Discard Non PVID packets” are also supported by the
KSZ8893FQL. These features can be set on a per port basis, and are defined in register 18, 34 and 50 for ports 1, 2
and 3, respectively.
