HAPTER 21: CONFIGURING SUBSCRIBER MANAGEMENT
Dest Mask Bit mask that applies to the destination IP address prior to
matching. The destination IP address and mask are the
matching criteria for the packet. By default, the destination IP
address and mask specify a filter that matches all destination
addresses. The mask entry is not necessarily the same as the
subnet mask.
TCP/UDP Filter
Source Port
(Applies
only to TCP
or UDP
filters.)
Optional. The source TCP or UDP port number to match.
Specify one of the following values:
■ Any: Match any source port
■ Number: Match a source port number to the TCP or UDP
port. The allowable TCP or UDP port number range is 0 to
65536. Note that specifying 65536 is the same as
specifying “Any.”
Destination
Port
(Applies
only to TCP
or UDP
filters.)
Optional. The destination TCP or UDP port number to match.
Specify one of the following values:
■ Any: Match any source port
■ Number: Match a source port number to a TCP or UDP
port. The allowable TCP or UDP port number range is 0 to
65536. Note that specifying 65536 is the same as
specifying “Any.”
TCP Flag Values Optional. The value of the TCP flags. The following is a list of
the TCP flag options. Leaving this field blank indicates a null
value (no flags).
TCP flags must always be a subset of the TCP flag mask in
order for the packet header to be matched.
■ For example, to match all packets where only the “urgent”
flag is set, and the mask is set at “syn”, and “fin,” the
resulting flag values would be “urgent” and the mask
would be: “urgent, syn, fin.”
urgent Indicates the TCP segment is urgent
ack Indicates the acknowledgement number field in the TCP field
segment is significant.
push Indicates the TCP software to push all the data sent so far
through the pipeline to the receiving application.
reset Indicates the connection is reset.
syn Indicates that the sequence numbers are resynchronized,
marking the beginning of a connection.
