Chapter 7 Provisioning: Configuring QoS for IP Telephony

Configuring QoS Using the IP Telephony Wizard

Selecting CallManager Connections

This step of the wizard describes the QoS requirements for Catalyst ports to which CallManagers or Voice Gateways are connected, and asks you to select the switch ports on which the wizard will configure the QoS settings for these connections in your network (network point 3 in Figure 7-1).

To select Call Manager connections:

Step 1 Select the switch port on which to configure QoS for the CallManager connection in the network, by selecting the check box next to the appropriate Ethernet port in the selection table.

For information about the columns in this table, see IP Telephony Wizard: Select CallManager Connections Page, page B-134.

Step 2 To remove any ports that were previously assigned for this voice role:

a.Click the Remove button in the Advanced section of the page.

A page appears, displaying the network elements assigned for the CallManager voice role.

For more information about this page, see IP Telephony Wizard: Remove Network Elements Page, page B-132.

b.Select the ports you want to unassign and click Remove. The page closes.

Step 3 Click Next.

If the Display Configuration Info. check box is selected, the Configuration Info page appears. After reviewing the assignments summary, click Next.

The voice policy groups and your CallManager ports assignments will be saved, and the next configuration step of the wizard appears (Selecting IntraLAN Connections).

Selecting IntraLAN Connections

In this step, the wizard helps you define the appropriate QoS for the internal LAN ports—the uplinks and downlinks (network points 4, 5 and 6 in Figure 7-1).

Note No QoS configuration is required on the uplink port of the Layer 2 Catalyst 3500 switch to the Layer 3 distribution switch port.

The correct QoS configuration for LAN connections is to trust DSCP from Layer 3 devices and trust CoS from Layer 2 devices. The wizard will configure the QoS automatically according to the type of neighboring switch.
