Determined by the dynamic MAC address table.
Table 5. STPID Egress Rules (Processor to Switch Port 5)
For packets from regular ports (Port 1
Port 4) to Port 5, the port mask is used to tell the processor which port the packet
was received on, defined as:
“0001” from Port 1,
“0010” from Port 2,
“0100” from Port 3,
“1000” from Port 4
No values other than the previous four defined should be received in this direction in the special mode. Table 6 shows the
egress rule for this direction.
