Address " operates the operation " source MAC is used only " by being identified in table 2 by " 0x0001 ", then two tuples<{ETC_ARG_
TID-1=0x0001 }, OPID=0x0001>Represent that " source client mac address is used only " is used as ETC standards.For another example, ETC_
ID 0x0005 indicate ETC standards and the use of the ETC_ARG_TID of ETC typess of variables are 0x0002 and 0x0006 and operate
OPID is 0x0003 namely ETC typess of variables by the variable that is identified in table 1 by " 0x0002 " " using only destination MAC
Location " and " the C-VLAN VID " identified by " 0x0006 ", operate by identified in table 2 by " 0x0003 " operation " and
VLAN VID are used together target MAC (Media Access Control) address ", then two tuple<{ ETC_ARG_TID-1=0x0002, ETC_ARG_TID-2=
0x0006 }, OPID=0x0003>Represent that " being used together destination client mac address with C-VLAN VID " marks as ETC
It is accurate.
