Setup and Configuration
• 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:
Configuring a Set Mark
1. Make sure the CLI is in Configuration mode.
2. Select the Set option by typing:
qos traffic-control advanced-configuration tcrules name mark-choice set
Where:
• name is the name of the traffic control rule
3. Configure the following parameter(s):
NOTE
The chain-options parameter specifies the chain in which the rule will be processed.
• Pre-Routing - Mark the connection in the PREROUTING chain.
This can be used with DNAT, SNAT and Masquerading rules in the firewall. An example of such
a rule is Source.IP:192.168.2.101, Chain-option: preroute or default, but the actual Source.NAT
address is 2.2.2.2.
• Post-Routing - Mark the connection in the POSTROUTING chain.
This can be used with DNAT, SNAT and Masquerading rules in the firewall. An example of such
rule is Destination.IP:192.168.3.101, Chain-option:preroute or default. In this case, the actual
destination address is 192.168.3.101, but it will be translated to 192.168.3.33 by DNAT. Another
example of a traffic control rule is Destination.IP:192.168.3.33, Chain-option:postrouting.
• Forward - Mark the connection in the FORWARD chain.
This is the default chain option and it can be used for normal IP traffic without any address or
port translation.
Parameter
object { object }
mark { mark }
mask { mask }
chain-options { chain-options }
