minimum bandwidth settings for the QoS profiles on the component switches. You can configure the
recommended QoS settings on your switches in one of two ways:
Auto Configure QoS button Calculates the recommended settings based on your default selections, and configures
them on all switches in the selected VLAN.
Manually Configure QoS Displays a dialog where you can modify the settings for individual switches, and then
button configure only selected devices.
To configure the default QoS settings on all switches in the VLAN, do the following:
1 On the QoS Settings page, select the default settings for the VLAN.
2 Click the Auto Configure QoS button at the bottom of the page.
The VoIP applet calculates the recommended bandwidth settings, and sends the configuration to each
switch in the VLAN.
To configure one or more individual switches with a particular setting that differs from the default
settings, do the following:
1 From the QoS Setting page, click the Manually Configure QoS... button at the bottom of the page.
This displays the Configure VoIP QoS Parameters dialog, as shown in
Figure 285: Configure VoIP QoS Configuration Parameters dialog
Initially, the left hand side of this dialog displays a list of the switches in the selected VLAN, and the
default configuration attributes you specified on the QoS Settings page. You can configure the
switches with the default settings, or modify the settings for one or more individual switches. For
example, if your organization uses several types of VoIP phones with different compression
algorithms, you may need to set different algorithms and QoS profile settings for the switches to
which these phones are connected.
NOTE
VoIP Configuration attributes can only be set on a switch-by-switch basis, meaning that all IP phones connected
to an individual switch are assumed to use the same compression algorithm. Settings cannot currently be
configured for individual ports.
When you move a switch to the Calculated Settings list, the VoIP applet calculates the minimum
bandwidth required to support the VoIP traffic. It makes the calculation based on the compression
algorithm and compression rate, the number of ingress ports in the VLAN, and the speed of the
