1. Port Using This Profile : Show the ports using this profile.
2. Strict Priority : Show the Strict Priority setting of this profile.
3. Delay Sensitive Application : Show the Delay Bound setting of the
profile.
4. Profile Name : The name of this profile. You can modify it.
5. Profile Status : The status (active / non-active) of this profile. You can
modify it. Because this switch support
four active profiles only. If you enable
this profile, that may cause some other
active profile being disable by the switch.
6. Bandwidth Partition : In "Bandwidth
Partitions" you can set the bandwidth allocation for the four transmit
queues on ports for Weight Fair Queue operation.
7. QoS with Flow Control : The flow control operation on port may conflict
with the QoS operation because the flow control operation will pause the
packets sending from the connected device to prevent packet lost when
the port is busy. But this operation will break the QoS request from the
application running on that device. In this case, the packets from ports
whose flow control function is enable will always be forwarded with the
lowest priority during scheduling so that they will not exposed to the
WRED dropping scheme to prevent any packet dropping in the QoS
operation. It can guarantee that no packets will be lost, but at the possible
expense of minimum bandwidth or maximum delay assurance.
If this function is enable, it will
force the QoS function still works
when the flow control is enabled.
However, only the best effort
traffics are not dropped. The high
priority traffics are still transmitted
first, but the packet may be dropped when the output
port is highly congested.
u
Port Configuration
With this function, you can select the QoS operation profile for each physical
port from the four active profiles. And you can see the fixed drop and
transmit priority settings of the port here. If the QoS operation is set to port-
based mode, these settings will be the QoS settings for the port.
