40 Classifying On Layer 4 Port Range Release Note
Software Version 2.7.6
C613-10462-00 REV A
Classifying On Layer 4 Port Range
Software Version 2.7.6 makes it easy to create a classifier that matches a range
of source or destination TCP or UDP ports. In previous software versions, you
could specify a port range by entering a port number and a mask. With
Software Version 2.7.6, you can simply enter the first and last numbers in the
range, separated by a hyphen. To do this, use one of the commands:
create classifier=rule-id [tcpsport={portid|port-range|any}]
[tcpdport={portid|port-range|any}]
[udpsport={portid|port-range|any}]
[udpdport={portid|port-range|any}] [other-options...]
set classifier=rule-id [tcpsport={portid|port-range|any}]
[tcpdport={portid|port-range|any}]
[udpsport={portid|port-range|any}]
[udpdport={portid|port-range|any}] [other-options...]
where port-range is a hyphen-separated range of TCP/IP or UDP/IP ports,
such as 5550-5554.
The following table describes the Layer 4 port parameters.
The existing functionality, which allows you to specify a port number and
mask, is still supported.
Command Change Summary
The following table summarises the modified commands (see Command
Reference Updates).
When... The classifier matches all packets whose...
TCPSport=port-range source TCP port is in this range.
TCPDport=port-range destination TCP port is in this range.
UDPSport=port-range source UDP port is in this range.
UDPDport=port-range destination UDP port is in this range.
Command Change
create classifier New port-range option on the Layer 4 port
parameters.
set classifier New port-range option on the Layer 4 port
parameters.
show classifier If a classifier specifies a range, the range is
displayed in the command output.
