Forwarding
The KSZ8842-PMQL/PMBL forwards packets using the algorithm that is depicted in the following flowcharts. Figure 7
shows stage one of the forwarding algorithm where the search engine looks up the VLAN ID, static table, and dynamic
table for the destination address, and comes up with “port to forward 1” (PTF1). PTF1 is then further modified by
spanning tree, IGMP snooping, port mirroring, and port VLAN processes to come up with “port to forward 2” (PTF2), as
shown in Figure 8. The packet is sent to PTF2.
