Corinex ADSL+ Gateway G Configuration
Corinex ADSL2+ Wireless Gateway G
The Rules configuration page will allow you to define IP matching fields to associate
with the priority queues associated with the named connections selected above in
the “QoS Setup Page” section.
There will be three primary fields for you to select:
• A Trusted mode check box.
• A traffic priority choice (EF2/High, Medium, Low). Note that EF1 is not a choice
for the user as it is meant only for voice control packets.
• An IP rules matching selection area.
The Gateway has two primary modes of operation with regard to queue traffic
prioritization: Trusted and Un-trusted. The Web UI will provide one check box to
enable trusted mode. In Trusted mode all rules will be applied first, regardless of
the setting of the TOS bits. After the rules have been exhausted the existing TOS bit
settings will be honored. If the Trusted mode box is unchecked this will indicate the
Un-trusted mode. Un-trusted mode will match first against all rules as in Trusted
mode. The difference is that if there is no match then a default rule will be used. The
default rule will have an associated queuing priority - Low.
Rule definitions will be defined by the user, by allowing the user to select matching
based on Source IP and Netmask, Destination IP and Netmask, IP Protocol, Source
Port range, Destination Port range, and Incoming Mac Port (switched LAN Port).
These selections will define a rule and be associated with a particular queue priority:
High, Medium, and Low. There is another option to choose a particular TOS mark-
ing. The allowed options are - No change, Normal service, Minimize monitory cost,
Maximize reliability, Maximize throughput and Minimize delay.
