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.
