♦ Destination IP Mask – Used to mask all or part of the destination IP address. If selected, QoS
looks for and matches the rule to packets being sent to the indicated destination IP address,
within the limits of the destination IP mask. The Destination IP Mask must not exceed the limits
set in the IP Classification fields.
♦ Source Port – Indicates if and which source port should be used when matching the rule to
packets.
♦ Destination Port – Indicates if and which destination port should be used when matching the
rule to packets.
♦ Condition – Specifies whether the packets' value should be different from the rules' value. The
possible values are:
◊
Bigger – Looks for a higher value than the exact data. Indicates that the parameter
values of a packet should be larger than the parameter values of the rule.
◊
Smaller – Looks for a lower value than the exact data. Indicates that the parameter
values of a packet should be smaller than the parameter values of the rule.
◊
Equal – Looks for the exact data. Indicates that all of the parameter values of a
packet should match all of the parameter values of the rule.
◊
Not Equal – Looks for non-matching data. Indicates that none of the parameter
values of a packet should match the parameter values of the rule. All values must be
different.
♦ Input Port – Indicates to which ports this rule applies. Packets arriving from the defined port
are forwarded according to the rule definition.
♦ Action – The action to be taken on packets when matched to the rule. The possible values
are:
◊
Block – Drops packets.
◊
Block and Trap – Drops packets and notifies the CPU that packets were dropped.
◊
Permit – Forwards packets. If the action is permit, then the output ports to which this
rule applies can be selected. This is the default value.
♦ Profile Pointer – Indicates which profile is attached to the rule. This field is only active if the
forwarding action of the packet is permit. The default value is 0. Zero is illegal if the action is
permit.
♦ Output Ports – Indicates to which ports this rule applies. This field is only active if the
forwarding condition of the packet is permit. The default value is all ports.
♦ Error Description – Indicates if the rule is valid. The error description can be one of the
following:
◊
The bandwidth specified exceeds the available specified bandwidth on the output
ports – Indicates that the amount of the bandwidth specified exceeds the available
amount of bandwidth as defined for the profile matching the rule.
◊
The QoS lock failed – Indicates that the rule cannot be applied to a packet. The
possible reasons are:
♦ Auto-negotiation is enabled.
♦ The port is not in full duplex mode.
♦ Status – Indicates rule's status. The rule status can be one of the following:
◊
Active – The rule is legal and currently active.
◊
Not in Service – The rule is currently not active.
