Configuring a Voice SSID with Network Director

 

Voice over IP has different requirements than data traffic and therefore has unique configuration requirements. For an explanation of voice traffic, see Understanding Voice Clients and Voice Traffic.

If your network is supporting both wireless data clients and voice clients, we recommend that you have two WLAN Service profiles, one for data and one for voice—this topic describes creating a WLAN Service profile for voice clients.

Note

WLAN Service profiles define the SSID name.

Creating a CoS Profile Dedicated to Voice

To be able to support latency-sensitive traffic such as voice traffic, you must create a dedicated CoS profile by entering voice-specific settings. This topic describes the typical settings that you can use to create a CoS profile dedicated to voice.

To create a CoS profile dedicated to voice:

  1. Click the Build Mode icon in the Network Director banner.
  2. Click CoS under Profile and Configuration Management in the Tasks pane.

    The Manage CoS Profiles page opens, displaying the list of current CoS profiles.

  3. Click Add on the Manage CoS Profiles page and select Wireless Controller (WLC) in the Device Family Chooser page.

    The Create CoS Profile for Wireless Controllers (WLC) wizard opens.

  4. Configure the following settings:
    • Provide a name for the CoS profile.

    • In the Voice CoS section, select VoIP-data.

    • (Optional) In the Voice CoS section, select Enable Bandwidth Limit and specify the maximum bandwidth that you want the system to reserve for voice traffic.

    • In the Access Categories section, make sure that the action corresponding to the Access Category—Voice is Permit.

  5. Click Done to save the settings.

For an explanation of all the CoS profile parameters, see Creating and Managing Wired CoS Profiles.

After you create the CoS profile, you then associate the CoS profile with an Authorization profile during creation of the Authorization profile. Next, you associate the Authorization profile with a WLAN Service profile to apply the CoS settings to all the users who connect to that SSID. For information on creating a WLAN Service profile (including mapping the Authorization profile) dedicated to voice, see Creating and Managing a WLAN Service Profile.
