PTF2
- Check receiving port's receive enable bit
- Check destination port's transmit enable bit
- Check whether packets are special (BPDU)
or specified
- RX Mirror
- TX Mirror
- RX or TX Mirror
- RX and TX Mirror
- Applied to MAC #1 and MAC #2
- IGMP will be forwarded to the host port
Figure 11. Destination Address Resolution Flow Chart in Stage Two
The KSZ8842M will not forward the following packets:
1.
Error packets.
These include framing errors, Frame Check Sequence (FCS) errors, alignment errors, and illegal size packet
errors.
2.
802.3x pause frames.
The KSZ8842M intercepts these packets and performs the flow control.
3.
"Local" packets.
Based on destination address (DA) lookup. If the destination port from the lookup table matches the port from
which the packet originated, the packet is defined as "local."
