Table 208: Diffserv Class Configuration Fields

Description
To configure a new DiffServ class, select Create. To modify or view an existing class,
select the name of the class from the dropdown menu.
Enter a class name. To create a new class, select the class type and click Submit. To
rename an existing class, click Rename after you enter the class name.
Lists all of the class types. Currently the hardware supports only the Class Type value
All, which means all the various match criteria defined for the class should be satisfied
for a packet match. All signifies the logical AND of all the match criteria.
The menu lists all match criteria you can add to a specified class. To configure the
criteria, select a match criteria from the list, and then click Add Match Criteria. The
screen changes to the criteria configuration page for that class. After you configure the
criteria, click Submit to apply the criteria to the class and return to the Class
Configuration page. To return to the Class Configuration page without applying the
criteria, click Cancel. The match criteria and configurable fields are as follows:
• Destination IP Address: Requires a packet's destination IP address to match the
address listed here. In the IP Address field, enter a valid destination IP address in
dotted decimal format. In the IP Mask field, enter a valid subnet mask to determine
which bits in the IP address are significant. Note that this is not a wildcard mask.
• Destination Layer 4 Port: Requires a packet's TCP/UDP destination port to match
the port you select. Select the desired L4 keyword from the list on which the rule can
be based. If you select Other, the screen refreshes and a Port ID field appears. Enter
a user-defined Port ID by which packets are matched to the rule. The valid range is 0–
65535.
• Any: All packets are considered to match the specified class and no additional input
information is needed.
• IP DSCP: Matches the packet's DSCP to the class criteria's when selected. Select
the DSCP type from the menu or enter a DSCP value to match. If you select Other,
enter a custom value in the DSCP Value field that appears. The valid range is 0–63.
• IP Precedence: Matches the packet's IP Precedence value to the class criteria's
when Enter a value in the range of 0–7.
• IP TOS: Matches the packet's Type of Service bits in the IP header to the class
criteria's when selected and a value is entered. In the TOS Bits field, enter a two-digit
hexadecimal number to match the bits in a packet's TOS field. In the TOS Mask field,
specify the bit positions that are used for comparison against the IP TOS field in a
packet.
• Protocol: Requires a packet's layer 4 protocol to match the protocol you select. If you
select Other, enter a protocol number in the field that appears. The valid range is 0-
255.
• Reference Class: Selects a class to start referencing for criteria. If the specified class
references another class, the Reference Class match criterion disappears from the
match list to prevent you adding another class reference, since a specified class can
reference at most one other class of the same type. Additionally, a Remove Class
Reference button appears on the screen. Click the button to remove the current class
reference.
• Source IP Address: Requires a packet's source port IP address to match the
address listed here. In the IP Address field, enter a valid source IP address in dotted
decimal format. In the IP Mask field, enter a valid subnet mask to determine which
bits in the IP address are significant. Note that this is not a wildcard mask.
• Source Layer 4 Port: Requires a packet's TCP/UDP source port to match the port
you select. Select the desired L4 keyword from the list on which the rule can be
based. If you select Other, the screen refreshes and a Port ID field appears. Enter a
user-defined Port ID by which packets are matched to the rule. The valid range is 0–
65535.
