Configuring UCC

About UCC

Unified Communication and Collaboration (UCC) can identify packets of specific protocols and increase the priority of the packets accordingly to accelerate packet forwarding and improve user experience.

Restrictions: Hardware compatibility with UCC

Support for this feature depends on the device model.

Configuring UCC for an audio or video application

Enabling UCC for an audio or video application

About this task

With UCC enabled for an audio or video application, the wireless service bound to the UCC profile will preferentially forward traffic from that application for wireless users that use the application to obtain higher-quality services.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Enable UCC for an audio or video application.

application app-name enable

By default, UCC is disabled for audio and video applications.

4.     Return to system view.

quit

5.     Create a service template and enter its view.

wlan service-template service-template

6.     Bind the service template to a UCC profile.

ucc-profile profile-name

Configuring priority marking for traffic from an audio or video application

About this task

Priority marking marks the priority of uplink traffic for an audio or video application and sends the priority to other service modules for them to process the traffic as configured.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Configure priority marking for traffic from an audio or video application.

application app-name flow-mark

By default, priority marking is not configured for traffic from audio and video applications.

4.     Return to system view.

quit

5.     Create a service template and enter its view.

wlan service-template service-template

6.     Bind the service template to a UCC profile.

ucc-profile profile-name

Dropping packets of an application in the specified subcategory

About this task

With this feature configured, the device drops application packets specified by the client. In this case, the wireless service bound to the UCC profile cannot provide the corresponding application services.

Restirctions an guidelines

After configuring the device to drop all packets of an application in the specified subcategory, you cannot configure a specific application any more.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Configure the device to drop packets of an application in the specified application subcategory.

application-subcategory appsubcategory [ app app-name ] drop

By default, the device does not drop application packets.

Configuring packet rate limit for an application in the specified subcategory

About this task

With this feature enabled, the wireless service bound to the UCC profile restricts the packet rate of a specified application. In a scenario featuring a large traffic volume, to ensure the service quality of key applications, you can set low rate limits for non-key application packets and high rate limits for key application packets.

Restrictions and guidelines

After specifying a rate limit for packets of all applications in a specified subcategory, you cannot configure a specific application any more.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Enable and specify a packet rate limit for an application in the specified subcategory.

application-subcategory appsubcategory [ app app-name ] rate-limit rate

By default, rate limit for application packets is disabled.

Specifying packet priorities for an application in the specified subcategory

About this task

With this feature configured, the wireless service bound to the UCC profile modifies the DSCP and 802.1p priorities for packets of an application in a specified subcategory.

Restrictions and guidelines

If you configure this feature with UCC enabled for an audio or video application for the same UCC profile, packets whose priorities are modified by this feature take precedence.

After specifying packet priorities for all applications in the specified subcategory, you cannot configure a specific application any more.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Specify packet priorities for an application in the specified subcategory.

application-subcategory appsubcategory [ app app-name ] remark { dot1p dot1p-value | dscp dscp-value }

By default, DSCP and 802.1p priorities for packets of an application in the subcategory are defined by the application itself.

Configuring UCC AP and AP group whitelists

About this task

Perform this task to allow only APs that belong to the UCC AP or AP group whitelist to collect and report UCC statistics to AC, reducing AC pressure from too many AP reports. In this way, pressure is also released for APs that do not belong to the UCC AP or AP group whitelist, because they no longer collect or report UCC statistics to AC.

Restrictions and guidelines

Only UCC APs for audio and video traffic are restricted by the whitelist.

Procedure (AP whitelist)

1.     Enter system view.

system-view

2.     Configure the UCC AP whitelist.

ucc whitelist ap ap-name

Procedure (AP group whitelist)

1.     Enter system view.

system-view

2.     Configure the UCC AP group whitelist.

ucc whitelist ap-group group-name

Bulk upgrading APR signature libraries for APs

About this task

For the audio and video feature of the UCC module to take effect on an AP, you also need to configure the DPI application identification feature. DPI application identification depends on the APR signature library. To ensure correct audio and video operation, upgrade the APR signature library on the AP in time. In a distributed AP network environment with AC + fit AP deployed, one AC might manage multiple APs. If the audio and video feature of the UCC module is enabled for multiple APs, use this command to upgrade the APR signature library for the APs in bulk.

Procedure

1.     Enter system view.

system-view

2.     Bulk upgrade APR signature libraries for APs.

apr wlan-signature update { file-name | default }

Display and maintenance commands for UCC

Execute display commands in any view.

 

Task	Command
Display APR signature library version information on the AC.	display apr wlan-signature library
Display UCC profile information.	display ucc profile [ profile-name ]
Display UCC AP whitelist information.	display ucc whitelist ap
Display UCC AP group whitelist information.	display ucc whitelist ap-group

 

UCC configuration examples

Example: Configuring UCC for an audio or video application

Network configuration

As shown in Figure 1, local forwarding is enabled in the network. Configure UCC for the Tencent Meeting application on the AC to optimize traffic between the clients to provide high-quality services.

Network diagram

Prerequisites

Assign IP addresses to interfaces, and make sure the devices can reach each other.

Make sure the APs can associate with the AC and the clients can obtain an IP address.
