Use the buttons to perform the following tasks:
• To define the match criteria for the selected class, click Add Match Criteria, In the Add Match Criteria
window, configure the fields shown in the table below, and click Submit to apply the changes. Once you
add a match criteria entry to a class, you cannot edit or remove the entry. However, you can add more
match criteria entries to a class until the maximum number of entries has been reached for the class.
• To remove the associated reference class from the selected class, click Remove Reference Class and
confirm the action.
• Click Refresh to refresh the page with the most current data from the switch.
To retain the changes across the switch's next power cycle, click System > Configuration Storage > Save.

Diffserv Class Configuration Fields (Continued)
Description
Select this option to require a packet's TCP/UDP source port to match the specified port or the port
number within a range of port numbers. If you configure a range, a match occurs if a packet's source
port number is the same as any source port number within the range. After you select this option, use
the following fields to configure a source port keyword, source port number, or source port range for
the match criteria:
• Protocol Select the desired L4 keyword from the list on which the match is based. If you select a
keyword, the other source port configuration fields are not available.
• Port End A user-defined L4 source port number to match or the source port number with the
lowest value within a range of ports.
• Port Start The source port with the highest value within the range of ports. This field is not
required if the match criteria is a single port.
Select this option to require a packet's TCP/UDP destination port to match the specified port or the
port number within a range of port numbers. If you configure a range, a match occurs if a packet's
destination port number is the same as any destination port number within the range. After you select
this option, use the following fields to configure a destination port keyword, destination port number,
or destination port range for the match criteria:
• Protocol Select the desired L4 keyword from the list on which the match is based. If you select a
keyword, the other destination port configuration fields are not available.
• Port End A user-defined L4 destination port number to match or the destination port number
with the lowest value within a range of ports.
• Port Start The destination port with the highest value within the range of ports. This field is not
required if the match criteria is a single port.
Select this option to require the packet's IP DiffServ Code Point (DSCP) value to match the specified
value. The DSCP value is defined as the high-order six bits of the Service Type octet in the IP header.
After you select this option, use one of the following fields to configure the IP DSCP match criteria:
• IP DSCP Keyword The IP DSCP keyword code that corresponds to the IP DSCP value to match. If
you select a keyword, you cannot configure an IP DSCP Value.
• IP DSCP Value The IP DSCP value to match.
Select this option to require the packet's IP Precedence value to match the number configured in the
IP Precedence Value field. The IP Precedence field in a packet is defined as the high-order three bits of
the Service Type octet in the IP header.
Select this option to require the packet's Type of Service (ToS) bits in the IP header to match the
specified value. The IP ToS field in a packet is defined as all eight bits of the Service Type octet in the IP
header. After you select this option, use the following fields to configure the ToS match criteria:
• IP TOS Bits Enter a two-digit hexadecimal number to match the bits in a packet's ToS field.
• IP TOS Mask Specify the bit positions used for comparison against the IP ToS field in a packet.
Select this option to require a packet header's Layer-4 protocol to match the specified value. After you
select this option, use one of the following fields to configure the protocol match criteria:
• Protocol The L4 keyword that corresponds to value of the IANA protocol number to match. If you
select a keyword, you cannot configure a Protocol Value.
• Protocol Value The IANA L4 protocol number value to match.
Select this option to require an IPv6 packet's flow label to match the configured value. The flow label
is a 20-bit number that is unique to an IPv6 packet, used by end stations to signify quality-of-service
handling in routers.
