Configuring QoS Marking
Quality of Service (QoS) marking applies a mark to important data packets that should receive preferential
treatment as they travel through the network. Only one QoS mark is allowed for each traffic control rule. Options
include:
• Set: Determines whether the packet or the connection is assigned the QoS mark.
• Modify: Changes the QoS mark value using an AND or OR argument.
• Save/Restore: Replaces the connection's QoS mark value with an assigned value.
• Continue: If the packet matches, no more traffic control rules are checked and the packet is automatically
forwarded to the specified chain.
• DSCP Marking: Determines whether the packet is assign the DSCP mark.
To configure the QoS mark for a traffic control rule, do the following:
