separate between start and end port numbers. A comma is used to separate
between entries. For example: 8900,9000-9005,9010,9016-9017.
„ Delete TCP Port Ranges: This option enables deleting TCP port ranges from
the list of priority port numbers. It is possible to delete discrete port numbers
and/or ranges. In ranges, a hyphen is used to separate between start and end
port numbers. A comma is used to separate between entries.
For example: 8900,9000-9005,9010,9016-9017.
„ Delete All TCP Port Ranges: This option enables deleting all TCP port ranges
from the list of priority port numbers.
„ Show TCP Port Ranges: Select this option to view the current TCP
RTP/RTCP Prioritization option and the list of TCP Port Ranges.
4.2.6.6.3.4 Low Priority Traffic Minimum Percent
This feature ensures that a certain amount of low priority packets, specified by
the Low Priority Traffic Minimum Percent (LPTMP) parameter, is transmitted even
at the expense of high priority traffic.
The mechanism guarantees a low priority traffic with a rate of LPTMP * RT /100,
where RT symbolizes the allowed traffic rate. The high priority traffic will thus not
be able to exceed (100-LPTMP) * RT/100. If the system receives high priority
traffic at a rate higher than this figure, some high priority packets will be
discarded.
The range is between 0 and 100 (%).
The default value is 0 (%).
4.2.6.6.3.5 Wireless Link Prioritization Parameters (AU)
To better support delay-sensitive and other high-priority traffic, a set of Wireless
Link Prioritization parameters enables configuring parameters that affect the
processes of gaining access to the wireless media and of transmitting high/low
priority packets.
The Wireless Link Prioritization feature is a licensed feature and is available only
in units with the suitable Feature License.
The time interval between two consecutive transmissions of frames is called Inter-
Frame Spacing (IFS). This is the time during which the unit determines whether
the medium is idle using the carrier sense mechanism. The IFS depends on the
type of the next frame to be transmitted, as follows:
