Section 4 - Advanced WLAN Configuration
To configure the DiffServ Class Configuration, refer to the table below:
Field
Description
Class Name
Enter a class name. To create a new class, select the class type. To rename an existing
class, click
Rename
after you enter the class name.
Class Type
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.
Class Match Selector (IPv4)
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. 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 the significant bits in the IP address. 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 id
0-63.
• IP Precedence
: Matches the packet’s IP Precedence value to the class criteria’s.
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.
• 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 the significant bits in the IP address. Note that this is not a wildcard
mask.
• Source L4 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 the packets are matched to the rule. The valid
range is 0-65535.
