Creating and Managing Wireless CoS Profiles
CoS profiles enable the grouping of class of service (CoS) parameters and apply them to one or more wireless interfaces. Network Director provides you with predefined traffic types for each wireless CoS profile that you create. These traffic types represent the most common types of traffic for the device type. Each of these templates has preconfigured values for all CoS parameters based on the typical application requirements. You can change the preconfigured values of these parameters to suit your requirements.

Managing Wireless CoS Profiles
From the Manage CoS Profiles page, you can:
Create a new wireless CoS profile by clicking Add. For directions, see Creating a Wireless CoS Profile.
Modify an existing wireless CoS profile by selecting it and clicking Edit.
Assign an existing wireless CoS profile to controllers by selecting it and clicking Assign. For directions, see Assigning a Wireless CoS Profile to Controllers.
Reassign an existing wireless CoS profile by selecting it and clicking Edit Assignment.
View information about a profile by selecting the profile and clicking Details.
Delete a wireless CoS profile by selecting a profile and clicking Delete.
Tip You cannot delete profiles that are in use—that is, assigned to objects or used by other profiles. To see the current assignments for a profile, select the profile and click Details.
Clone an existing wireless CoS profile by selecting it and clicking Clone.
Table 1 describes the information provided about wireless CoS profiles on the Manage CoS Profiles page. This page lists all wireless CoS profiles defined for your network, regardless of the scope you selected in the network view.
Table 1: Manage Wireless CoS Profile Fields
Field | Description |
|---|---|
Profile Name | Name given to the profile when the profile was created. |
Family Type | The device family on which the profile was created, either EX Series Switches, Wireless LAN Controllers, Campus Switching ELS, or Data Center Switching. |
Description | Description of the profile that was entered when the profile was created. If the profile was created by using the CLI and then discovered by Network Director, the description is Profile created as part of device discovery. Tip: To display the entire description, you might need to resize the Description column by clicking the column border in the heading and dragging it. |
Creation Time | Date and time when the profile was created. |
Last Updated Time | Date and time when the profile was last modified. |
User Name | The username of the user who created or modified the profile. |
All columns might not be displayed. To show or hide fields, click the down arrow on the field header, select Columns, and select or clear the check box adjacent to the field that you want to show or hide.
Creating a Wireless CoS Profile
In Network Director, you can create a wireless CoS profile to group a set of Class of Service parameters and apply it to one or more wireless network sessions.
For a CoS profile, you must specify the profile name. You can optionally reconfigure the default settings.
- Under Views, select one of these options: Logical
View, Location View, Device View or Custom Group View.
Tip Do not select Dashboard View, Datacenter View, or Topology View.
- Click
in the
Network Director banner. - In the Tasks pane, expand Wireless, expand Profiles, and then select CoS.
The Manage CoS Profiles window opens.
- In the Manage CoS Profiles, click Add to add a new wireless CoS profile.
- Specify the wireless CoS Profile settings as described in both the online help and in Specifying Settings for a Wireless CoS Profile.
- Click Done to save the wireless CoS profile.
The system saves the CoS profile and displays it on the Manage CoS Profiles page.
Specifying Settings for a Wireless CoS Profile
To configure a wireless CoS profile:
- Enter the settings described in Table 2. Required settings are indicated
by a red asterisk (*) that appears next to the field label in the
user interface.
Table 2: CoS Profile Basic Settings for Wireless
Field
Action
Profile Name
Type a unique name that identifies the profile.
You can use up to 32 characters for profiles created for wireless devices. Profile name must not contain special characters or spaces. Note that profiles that are automatically created by Network Director as part of device discovery or out-of-band changes might contain the underscore (_) character.
Description
Type a description of the profile.
Session CoS Enable Bandwidth Limit
Select Enable Bandwidth Limit if you want to specify a bandwidth limit for a given session, and then type the Maximum Bandwidth (Kb/s) (full duplex rate) for aggregates of access categories (ACs) for a wireless client. Downstream packets are shaped and upstream packets are policed.
Enable Static CoS
Select Enable Static CoS to assign the same CoS level to all traffic on the Service profile SSID, regardless of 802.1p or DSCP markings in the packets themselves, and regardless of any filters that mark CoS. This option provides a simple way to configure an SSID for priority traffic such as VoIP traffic.
Select the CoS Value that you want the controller to assign to all user traffic.
Trust Client DSCP
Select Trust Client DSCP to enable the controller to use the client DSCP (Differentiated Services code point) for radio ingress traffic and ignore Wi-Fi Multimedia (WMM).
Voice CoS Traffic Class
Specify the traffic class for the data type voice:
None—Select to indicate that no traffic class is required for voice traffic.
VoIP-Data—Select to indicate that you want to enable a traffic class for voice traffic.
If you selected VoIP-Data, you can additionally select Enable Bandwidth Limit if you want to specify a bandwidth limit for voice traffic, and then type the maximum bandwidth (full duplex rate) for aggregates of access categories (ACs) for a wireless client. Downstream packets are shaped and upstream packets are policed.
If you selected VoIP-Data, you can additionally select Enable Static CoS to assign the same CoS level to all traffic on the Service profile SSID, regardless of 802.1p or DSCP markings in the packets themselves, and regardless of any firewall filters that mark CoS. This option provides a simple way to configure an SSID for priority traffic such as VoIP traffic. Select the CoS value that you want the controller to assign to all user traffic.
Access Categories
Access Categories includes up to four access categories for QoS. You can modify the action (Permit or Demote) corresponding to each forwarding queue to suit your requirements.
If you remove any of the four default types (Background, Best Effort, Voice, and Video) by selecting it and clicking Remove, you can add additional categories until there are four. To add a category:
- Click Add in the Access Categories box. The Add Access Category window appears.
- Select an Access Category, Background, Best-Effort, Voice, or Video.
- Select an action to be applied to packets in the forwarding queue, either Permit or Demote.
- Click OK.
The Add Access Category window closes and the access category is added to the list of Access Categories.
- Click Done.
What To Do Next
After you create a CoS profile for wireless devices, associate the CoS profile with an Authorization profile during Authorization profile creation. This Authorization profile is then associated with a WLAN profile (during WLAN profile creation) to apply the CoS settings to all the users who connect to the WLAN SSID. For directions, see Creating and Managing Wireless Authorization Profiles andCreating and Managing a WLAN Service Profile.
