IP Rules Table
The IP Rules Table allows you to define the filters that determine which network traffic is managed.
The IP Rules Table contains two types of filters:
♦ Filters that determine how packets are matched to a rule. For example, the Protocol,
ToS, Source Port, Destination Port, Input Ports, and Output Ports fields.
♦ Filters that determine what forwarding action is taken on packets. For example, the
Condition and Actions fields.
Note: The fields that appear in the IP Rules Table reflect the IP Classification Fields that were
selected.
Note: Rules cannot be added to the IP Rules Table if the IP Classification Fields have not been defined.
To display the IP Rules Table:

The IP Rules Table contains fields that reflect the type of IP Classification Fields selected and
additional parameters for forwarding packets:
♦ Description – The user-defined description of the rule.
♦ ToS – Type of Service. Indicates the predefined ToS used to classify packets. If selected, the
rule applies to packets matching the ToS type. The possible values are 0-3. The default value is
disabled.
♦ Protocol – The protocol type. Indicates the type of predefined protocols used to classify
packets. If selected, the rule applies to packets of this indicated protocol. The possible values are
TCP or UDP.
♦ Source IP – The source IP address of packets being matched to the rule. If selected, QoS
matches the rule to packets arriving from the indicated source IP address.
♦ Source IP Mask – Used to mask all or part of the source IP address. If selected, QoS looks for
and matches the rule to packets being sent from the indicated source IP address, within the
limits of the Source IP Mask. The Source IP Mask must not exceed the limits set in the IP
Classification fields.
♦ Destination IP – The destination address of packets being matched to the rule. If selected,
QoS looks for and applies the rule to packets being sent to the indicated IP address.
♦ Select QoS > IP > IP Rules Table. The IP Rules Table opens:
