Creating A Qos Classifier - Symbol ES3000 Manual

• No-match actions act on packets that are in-bound to the switch and which do not match
the characteristics specified by the classifier.
Each of the components of a policy—classifier, action, port list—is identified by an index when it is
created. After all of the components have been created, the policy itself is created by specifying a
sequence number and the index numbers of each of its components. A written list of the classifier,
action, and port list indices is helpful during this step.
Up to sixteen policies can be operative for each port, but four of these policies are reserved for system
use. No more than twelve uder-defined policies can apply to a particular port.
After creation, policies are applied in sequence order. When a packet is matched with a policy which
specifies an in-profile action or an out-profile action, then that action is taken and no more policies
are considered for that packet.

8.2.1 Creating a QoS Classifier

Classifiers determine which packets are effected by a QoS policy. To create a classifier, go to the
Create Classifier page in the web interface (QoS > Policy Config. > Create Classifier) or the menu
interface. Classifiers can also be created using the
The following parameters can be specified in a classifier:
• Source MAC address
• Destination MAC address
• VLAN ID number
• DSCP value: The existing Differentiated Services Code Point in the packet
• Protocol number: The Internet Protocol version 4 protocol number. See
Protocol Numbers on page
• Source IP address
• Destination IP address
• Source port: The source Ethernet Layer 4 port number. See
Numbers on page
• Destination port: The destination Ethernet Layer 4 port number.
If more than one parameter is specified in a classifier, both must match for the classifier to apply. Any
parameter which is not specified is ignored for purposes of matching the classifier to the traffic. For
example, a classifier which specified destination IP address as 192.168.2.2 and specified no other
parameters, would apply to all traffic with that destination IP address. A classifier which specified
