Check
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
- MAC #3 is reserved for
microprocessor
- IGMP will be forwarded to port 3
Figure 5. Destination Address Resolution Flow Chart, Stage 2
The KS8993M will not forward the following packets:
1.
Error packets. These include framing errors, FCS errors, alignment errors, and illegal size packet errors.
2.
802.3x pause frames. The KS8993M will intercept these packets and perform the appropriate actions.
3.
"Local" packets. Based on destination address (DA) lookup. If the destination port from the lookup table
matches the port where the packet was from, the packet is defined as "local."
