sport
is a hexadecimal representation of incoming ports, and
dport
is
a hexadecimal bitmask of representation of outgoing ports. Because
bitmasks are difficult to determine, a list of numbers for every
combination of source and destination ports is listed in Appendix A.
Packets arriving at the switch with the destination MAC address from
any port specified in
sport
are transmitted to all ports specified in
dport
.
