Filtering Criteria
QoS policies identify packets using filtering criteria. The AT-8100 web
interface offers seven criteria:
Source and destination IP addresses
Source and destination MAC addresses
Source and destination TCP ports
Source and destination UDP ports
VLAN IDs
CoS value
DSCP value
Actions
The action defines the response to packets that match the filtering criteria
of a QoS policy. There are three actions that you can choose from using
the AT-8100 web interface:
Priority Queue
— This action causes a port to place all ingress
packets that match the filtering criteria to the specified priority queue.
Mark DSCP
— This action causes a port to change the DSCP value of
all ingress packets that match the filtering criteria with the specified
DSCP value.
Mark CoS
— This action causes a port to change the CoS value of all
ingress packets that match the filtering criteria with the specified CoS
value.
How Ingress
Packets are
Selected with
Filtering Criteria
A QoS policy can have more than one filtering criterion. A QoS policy that
has one filtering criterion that specifies a particular source IP address, for
example, selects only packets with the specified source address and
applies the specified action. A QoS policy that has two filtering criteria that
specify a particular VLAN ID and DSCP value, for example, selects only
packets that match the specified VLAN ID
and
DSCP value.
Guidelines
Here are the QoS guidelines:
A QoS policy can have a “Priority Queue,” “Mark DSCP,” or “Mark
CoS” action. The priority queue action allows a port to place ingress
packets that match the filtering criteria to the specified priority queue.
The Mark DSCP action causes a port to change the DSCP value of all
ingress packets that match the filtering criteria with the specified DSCP
Specifying a MAC address
4000 - 4699
Specifying no address
3000 - 3699 and 4000 - 4699
