Port group packet
filter example
In this example, packets are not forwarded to ports in groups 3 and 8.
Name “Discard Groups 3 and 8”
pushSPGM # Get source port group mask
pushLiteral.l 0x0084 # Select bits 3 and 8
and # If port group bits 3 & 8 are common
# with SPGM, then non-zero value is
# pushed onto stack
pushLiteral.l 0 # Push zero
eq # Only if SPGM is not in port groups
# corresponding to bits 3 & 8, then
# packet is forwarded
