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.

UCC configuration tasks at a glance

To configure UCC, perform either of the following tasks:

·     Configuring SIP-based UCC

·     Configuring Skype4B-based UCC

Configuring SIP-based UCC

About this task

SIP-based UCC enables the device to identify SIP protocol packets from wireless clients and preferentially forward audio and video traffic for the wireless clients.

Restrictions and guidelines

SIP-based UCC does not support analysis of encrypted SIP protocol packets or fragments.

Procedure

1.     Enter system view.

system-view

2.     Create a UCC profile and enter its view.

ucc profile profile-name

3.     Enable SIP-based UCC in the UCC profile.

sip enable

By default, SIP-based UCC is disabled for a UCC profile.

4.     Return to system view.

quit

5.     Enter service template view.

wlan service-template service-template-name

6.     Bind a UCC profile to the service template.

ucc-profile profile-name

By default, no UCC profile is bound to a service template.

Configuring Skype4B-based UCC

About this task

Skype for Business (Skype4B)-based UCC enables the device to analyze Skype4B packets from wireless clients and preferentially forward the audio, video, and application sharing traffic for the wireless clients

Procedure

1.     Enter system view.

system-view

2.     Enable the device to communicate with the Skype4B server and specify the port number.

skype4b listener { http-port http-port-num | https-port https-port-num ssl-policy ssl-policy-name }

Make sure the port numbers are different if you configure both HTTP and HTTPS services.

3.     Create a UCC profile and enter its view.

ucc profile profile-name

4.     Enable Skype4B-based UCC.

skype4b enable

By default, Skype4B-based UCC is disabled.

5.     (Optional.) Configure priority marking for Skype4B application sharing packets.

skype4b app-share remark { dscp dscp-value | dot1p dot1p-value }

6.     (Optional.) Configure priority marking for Skype4B video packets.

skype4b video remark { dscp dscp-value | dot1p dot1p-value }

By default, the DSCP value is 34 and the 802.1p priority is 4 for Skype4B video packets.

7.     (Optional.) Configure priority marking for Skype4B voice packets.

skype4b voice remark { dscp dscp-value | dot1p dot1p-value }

By default, the DSCP value is 46 and the 802.1p priority is 6 for Skype4B voice packets.

UCC configuration examples

Example: Configuring SIP-based UCC

Network configuration

As shown in Figure 1, the SIP server installed with third-party VoIP server software acts as both the SIP agent server and SIP registration server to manage SIP user registration and respond to user calls. Client 1 and Client 2 use the AC as their gateway, and they can call each other through the client software installed on them. Centralized forwarding is configured.

Configure UCC to optimize multimedia traffic between the clients.

Figure 1 Network diagram

 

Procedure

1.     Assign IP addresses to interfaces, as shown in Figure 1. (Details not shown.)

2.     Verify that the APs can associate with the AC and the clients can obtain an IP address.

3.     Configure the SIP server:

Install third-party VoIP server software, and configure a username (telephone number) and password for the clients.

4.     Configure Client 1 and Client 2:

Install third-party VoIP client software, specify the IP address of the SIP server, username (telephone number), password, and other parameters.

5.     Configure the AC:

# Create UCC profile 1, and enable SIP-based UCC in the UCC profile.

<Sysname> system-view

[Sysname] ucc profile 1

[Sysname-ucc-profile-1] sip enable

[Sysname-ucc-profile-1] quit

# Bind the UCC profile to service template service1.

[Sysname] wlan service-template service1

[Sysname-wlan-st-service1] ucc-profile 1

[Sysname-wlan-st-service1] quit

# Bind the UCC profile to service template service2.

[Sysname] wlan service-template service2

[Sysname-wlan-st-service2] ucc-profile 1

[Sysname-wlan-st-service2] quit

Verifying the configuration

# Place a call from Client 1 to Client 2. (Details not shown.)

# Execute the following command to verify that multimedia traffic has been forwarded from Client 1 to Client 2.

Example: Configuring Skype4B-based UCC

Network configuration

As shown in Figure 2, all network users use Skype4B for communication.

The Skype4B server (including front-end and back-end) manage user registration and calls, and the Dialog Listener listens for Skype dialogs on the AC. The two servers are deployed on the same physical server.

The SDN Manager obtains dialog information from the Dialog Listener and establishes an HTTP or HTTPs connection with the AC to issue dialog information.

The AC is the client traffic forwarder, and the switch is the gateway for the clients. The clients use Skype4B client software to place calls to each other.

Configure Skype4B-based UCC on the AC to optimize Skype4B traffic between the clients to provide high-quality Skype4B services.

Figure 2 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.

Deploy the Skype4B server, Skype4B client, SDN Manager, and Dialog Listener.

Procedure

# Enable the device to communicate with the Skype4B server and specify the port number as 5000. Make sure this port number is the same as the port number configured on the SDN Manager.
