together with the port mirror feature, explained in Chapter 23, “Port
Mirror” on page 451.
The SRC_IPADDRESS and DST_IPADDRESS parameters specify the
source and destination IPv4 addresses. Choose from the following
options:
 any— Matches any IPv4 address.
 ipaddress/mask— Matches packets that have an IPv4 address of a
subnet or an end node. The mask is a decimal number that
represents the number of bits in the address, from left to right, that
constitute the network portion of the address. For example, the
subnet address 149.11.11.0/24 has a mask of “24” for the first
twenty-four bits of the network portion of the address. The IPv4
address and the mask are separated by a slash (/); for example,
“149.11.11.0/24.”
 host ipaddress— Matches packets with a specified IPv4 address
and is an alternative to the IPADRESS/MASK variable for
addresses of end nodes. The HOST keyword indicates that the
IPv4 address is assigned to a specific end node and that no mask
is required.
The eq parameter matches packets that are equal to the UDP port number
specified by the SRC_UDP _PORT or DST_UDP _PORT parameter.
The lt parameter matches packets that are less than the UDP port number
specified by the SRC_TCP_PORT or DST_TCP_PORT parameter.
The gt parameter matches packets that are greater than the UDP port
number specified by the SRC_UDP _PORT or DST_UDP _PORT
parameter.
The ne parameter matches packets that are not equal to the UDP port
number specified by the SRC_UDP _PORT or DST_UDP _PORT
parameter.
The range parameter matches packets with UDP port numbers within the
range. Separate the numbers of the range by a space. For instance:
range 4 10
The src_udp_port parameter specifies the source UDP port number. The
range is 0 to 65535. Omit this parameter to match any UDP port number
within the 0 to 65535 range.
The dst_udp_port parameter specifies the destination UDP port number.
The range is 0 to 65535. Omit this parameter to match any UDP port
number within the 0 to 65535 range.
