support four active profiles, so if you enable this profile, other active profiles might be disabled by the

switch.

Bandwidth Partition – Allows you to set the bandwidth allocation for the four transmit queues on ports for

Weight Fair Queue operation.

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 sent from the connected device to prevent packet loss

when the port is busy.

device. In this case, the packets from ports whose flow control function is enabled will always be forwarded

with the lowest priority during scheduling so that they are not exposed to the WRED dropping scheme to

prevent any packet dropping in the QoS operation. This can guarantee that no packets will be lost, but at

the possible expense of minimum bandwidth or maximum delay assurance. If this function is enabled, it will

force the QoS function to work when the flow control is enabled. However, only the best effort traffic is not

dropped. The high priority traffic is still transmitted first, but the packet may be dropped when the output port

is highly congested.

Port Configuration

With this function, you can select the QoS operation profile for each physical port from the four active profiles.

The fixed drop and transmit priority settings of the port are set in this menu. If the QoS operation is set to port-

based mode, these settings will be the QoS settings for the port.

With this function, you can set the traffic rate control for each physical port. (You can set the rate control for

10/100M ports only.) The 2600M supports ten levels of rate control from line speed. You select one of the ten

levels to limit the traffic rate allowed on ports. You can also select the traffic type for rate control to either

streaming or burst.

Note: If the Delay Sensitive Application option of any active profile is enabled, an error message will be

displayed when you try to set the rate control. It is recommended to try to activate another profile with the Delay

Sensitive Application option disabled because the Delay Bound scheduling operation conflicts with rate

control operation of the switch. It is recommended to use Profiles 3, 4, 7 or 8 as the activity profiles for rate

control operation because they are Delay Sensitive Application disabled.
