Vigor2750 Series User’s Guide 246
From the above page, we can see TCP/UDP Ports 22, 23 and 5060 are under High
Traffic Class .
We can add new rule by clicking the button; delete rules by clicking button
and modifying rules by clicking button.
All the Ports mentioned mean the destination ports.
3. Vigor2130 provides 5 QoS configuration profiles. Users can use different QoS profiles
at different time.
For example, we can use default QoS profile in working hours but use another profile
(e.g. UDP port 6881 for BT with medium priority) in non-working hours.
4. The last step is to select the QoS profile and configure the Queuing Weighted mode
and rate.
Weighted mode means Vigor will process the packets from different classes
according to the setting rate. For example, process 8 packets from High class, 4
packets from Medium class, 2 packets from Normal class and 1 packet from Low
class at the same time.
Strict Priority mode means Vigor will always process the packets from High Class at
first, then the packets from Medium class, then the normal class.
The application of High priority class may run out all the bandwidth and it may cause
the traffics from lower class stopping work.
