The tcpflags parameter specifies the TCP flags of an IPv4 or IPv6 packet, one or more of urg, ack, rst, syn and fin. If any is specified, TCP flags are ignored. The default is any.

The icmptype parameter specifies the ICMP type of an IPv4 packet. This can be one of the list of available options, or a decimal value in the range 0 to 255. The icmptype parameter is valid only if the ipprotocol parameter has either not been specified, or ipprotocol=icmp has been specified. If any is specified, the ICMP type is ignored. The default is any.

The icmpcode parameter specifies the ICMP code of an IPv4 packet. This can be one of the list of available options, or a decimal value in the range 0 to 255. The icmpcode parameter is valid only if the ipprotocol parameter has either not been specified, or ipprotocol=icmp has been specified. If any is specified, the ICMP code is ignored. The default is any.

The igmptype parameter specifies the IGMP type of an IPv4 packet. This can be one of the list of available options, or a hexadecimal value in the range of 00 to ff. The igmptype parameter is valid only if the ipprotocol parameter has either not been specified, or ipprotocol=igmp has been specified. If any is specified, the IGMP type is ignored. The default is any.

The eipbyte01 to eipbyte16 parameters each specify the properties of a single byte field to match in the Layer 3 header and data of a non-IPv4 and non-IPv6 packet. The eipbyte01 parameter must be used as the first byte field, and additional byte fields must increment sequentially, for example eipbyte01, eipbyte02, eipbyte03. Each field must have a greater offset than the field that precedes it.

For each byte field you want to match, specify a byteoffset and a bytevalue, and optionally, a bytemask.

■byteoffset is a decimal number in the range 0 to 65. This specifies the location of the byte to match. It refers to the offset from the start of Layer 3, after the Layer 2 encapsulation format of an Ethernet frame.

■bytevalue is a 2-digit hexadecimal number. This specifies the value of the byte at the frame position determined by the byteoffset. The classifier matches packets that have this value at this location.

■(optional) bytemask is a 2-digit hexadecimal number. This specifies an eight-bit binary mask to apply to the field. When a bit is set to 1 in the mask, the value of the bit at the same position in the byte is used to determine a match. If the bytemask is 0, the corresponding bit is ignored. The default is ff, which means the classifier matches against all bits in the byte.
