Example for Configuring Priorities for Skype4B Packets
Networking Requirements
Enterprise users can access the network through WLANs, which is the basic requirement of mobile office. Furthermore, users' services are not affected during roaming in the coverage area.
The administrator requires that voice and video packets of the Skype4B software have a higher priority than desktop sharing and file transfer packets to ensure good user experience in voice and video services.
For the WLAN access configuration, see Related Topics.

Configuration Roadmap
Configure priorities for Skype4B packets to set higher priorities for voice and video packets than those of desktop sharing and file transfer packets.
Configure the AC to interact with the Skype4B server.
Configuration Notes
- No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.
Procedure
- Configure priorities for Skype4B packets.
# Choose .
# In the AP group list, click ap-group1. Click
in front of VAP Configuration. Under it, click
in front of wlan-net. Click UCC Profile. The UCC Profile page is displayed.
# Click Create. The Create UCC Profile page is displayed.
# Enter the UCC profile name wlan-ucc in Profile name and click OK. The parameter setting page of the new UCC profile is displayed.
# Configure priorities for Skype4B packets according to the following figure.
# Click Apply. In the dialog box that is displayed, click OK.
- Configure the AC to interact with the Skype4B server.
# Choose . The Skype4B page is displayed.
# On the Skype4B page, set Skype4B listener to ON, Type to HTTP, and HTTP port to 9000.
The port number of the HTTP service specified on the AC must be consistent with the port number on the Skype4B server.
You need to specify the IP address of the AC for the Skype4B server and the port number of the Skype4B server.
# Click Apply. In the dialog box that is displayed, click OK.
- Verify the configuration.
- The priorities of Skype4B voice and video packets are higher than those of Skype4B desktop sharing and file transfer packets. Therefore, users are provided with good voice and video service experience.
