LAPAC1750PRO Access Point Software User Manual
Destination MAC
Mask
Enter the destination MAC address mask specifying
which bits in the destination MAC to compare against
an Ethernet frame.
An f indicates that the address bit is significant, and a
0 indicates that the address bit is to be ignored. A MAC
mask of ff:ff:ff:ff:ff:ff matches a single MAC address.
VLAN ID Select the field and enter a VLAN ID to be matched for
packets. The VLAN ID range is 0–4095.
IPv4 Class Maps
Service Type You can specify one type of service to use in matching
packets to class criteria.
IP DSCP To use IP DSCP as a match criterion, select the check
box and select a DSCP value keyword or enter a DSCP.
Select from List
Select from a list of DSCP types.
Match to Value
Enter a DSCP Value to match (0–63).
IP Precedence Select this field to match the packet’s IP Precedence
value to the class criteria IP Precedence value.
The IP Precedence range is 0–7.
IP TOS Bits Select this field and enter a value to use the packet’s
Type of Service bits in the IP header as match criteria.
The TOS bit value ranges between (00–FF). The high-
order three bits represent the IP precedence value.
The high-order six bits represent the IP Differentiated
Services Code Point (DSCP) value.
IP TOS Mask Enter an IP TOS mask value to perform a boolean AND
with the TOS field in the header of the packet and
compared against the TOS entered for this rule.
The TOS Mask can be used to compare specific bits
(Precedence/Type of Service) from the TOS field in the
IP header of a packet against the TOS value entered for
this rule. (00–FF).
Delete Class Map Check to delete the class map selected in the Class Map
Name menu. The class map cannot be deleted if it is
already attached to a policy.
To delete a Class Map, select the Delete Class Map option and click Save.
Policy Map
Use the Policy Map page to create DiffServ policies and to associate a collection
of classes with one or more policy statements.
The access point supports up to 50 policy maps.
Packets are classified and processed based on defined criteria. The classification
criteria are defined by class on the Class Map page. The processing is defined by
a policy’s attributes on the Policy Map page. Policy attributes may be defined
on a per-class instance basis, and it is these attributes that are applied when a
match occurs. A policy map can contain up to 10 class maps. When the policy is
active, the actions taken depend on which class matches the packet.
Packet processing begins by testing the class match criteria for a packet. A
policy is applied to a packet when a class match within that policy is found.
NOTE:
The Policy Map page displays the policy configuration fields only if a
policy map has been created. To create a policy map, enter a name in the
Policy Map Name field and click Add Policy Map.
To create a DiffServ policy, click the Configuration > Qos and Access Control >
Policy Map tab. The following image shows the page after a policy map has
been created.
