Select the entry from the table that you wish to change,
then click Edit Class Element. Add rules to a selected
class using the ACL list drop-down menu or the IP DSCP,
IP Precedence and VLAN text fields provided, then click
Add.
QoS > DiffServ Settings > Edit Class Element
Class Rule Edits the rules for the class by specifying
the type of traffic based on an access list, a DSCP or IP
Precedence value, or a VLAN.
ACL Name of an access control list. Any type of ACL can
be specified, including standard or extended IP ACLs and
MAC ACLs. (Range: 1-16 characters)
IP DSCP A DSCP value. (Range: 0-63)
IP Precedence An IP Precedence value. (Range: 0-7)
VLAN A VLAN value. (Range: 1-4094)
Add Adds the specified criteria to the class. Only one
entry is permitted per class.
Remove Deletes the selected criteria from the class.
Policy Map
A policy map can contain multiple class statements that
can be applied to the same interface with the Service
Policy Settings. You can configure up to 63 policers (that
is, class maps) for Fast Ethernet and Gigabit Ethernet
ingress ports.
QoS > DiffServ Settings > Edit Policy Element
Policing is based on a token bucket, where bucket depth
(that is, the maximum burst before the bucket overflows)
is by specified the “Burst” field, and the average rate tokens
are removed from the bucket is by specified by the “Rate”
option.
After using the policy map to define packet classification,
service tagging, and bandwidth policing, it must be
assigned to a specific interface by a service policy to take
effect.
Policy name The name of the policy map. (Range: 1-32
characters for the name)
Description A brief description of the Policy. (Range 1-

selected policy, or Remove Policy to delete the policy.
Class Name Name of class map. Use the drop-down
menu to select a different policy.
Action Configures the service provided to ingress traffic
by setting a CoS, DSCP, or IP Precedence value in a matching
packet. (Range - CoS: 0-7, DSCP: 0-63, IP Precedence: 0-7)
Enable Meter Check this to define the maximum
throughput, burst rate, and the action that results from a
policy violation.
Rate (kbps) Rate in kilobits per second. (Range: 1-
100000 kbps or maximum port speed, whichever is
lower)
Burst (byte) Burst in bytes. (Range: 64-1522)
