Function: Define a field as an ACL condition. Value indicates the value to be matched; Base
Addr indicates the reference point of a packet; End of Tag indicates the end of the Tag field is
the reference point; End of EthType indicates the end of the EthType field is the reference
point; End of IP Header indicates the end of the IP header field is the reference point; Offset
indicates the offset of the value compared with the reference point. If the Offset of a packet
compared with Base Addr is Value , then the condition is met.
Note:
It is not necessary to set all these parameters, but at least one parameter needs to be set. If
only one parameter is required, then leave all the other parameters empty.
