Chapter 6 - QoS Configuration
Overview
The XC-DPG503 provides QoS, which supports the high quality of network service. Classifying outgoing packets
based on some policies defined by users provides real-time applications to get better response or performance.
Settings - QoS Setup
QoS Feature • Enable QoS – This will allow users enable QoS function.
• Queuing Method – The methods that how you manage your queue- Priority queuing. It is
one of the first queuing variations to be wildly implemented
IP TOS (Type of Service)
Feature
• Process TOS Field –An 8-bit field in the IP packet header designed to contain values
indicating how each packet should be handled in the network. If you choose “enable” then it
will enable this function to process the IP Type of Service field.
• Overwrite policy priority – Choose “yes” to set the priority of the TOS field in IP packet
overwrite the priority defined in policy configuration
Policy Configuration
When you use QoS, you must define some policies to make some packets to have higher priority to pass
through.
Settings - Policy Configuration
Network Admission Policy
This section identifies each policy:
Policy Name List – Ignore this list when adding a new Policy. To edit an existing entry, select it from the list and click the
“Select” button. The data fields will then be updated with data for the selected entry.
Policy Name – Enter a suitable name. Generally, you should use the “Policy Name” for the network traffic.
Source Address – Define the source address of packets here. It has two types like IP address or MAC address. If you select IP
address, you can define IP address range. Otherwise you may define up to four MAC addresses.
Destination Address – Define the destination address of packets here. The explanation is as the same as above.
Protocol Type – The field defines traffic packet type, i.e. IP,TCP and UDP.
Source Port – Define the source port of packets here.
Destination Port – Define the destination port of packets here.
Priority Queue – This defines a packet. If it meets all conditions defined above, it will be serviced with some priority level.
