Converged networks are increasingly common. Present-day networks support integrated voice, video, and data traffic. Carrying voice, video, and data traffic over a single transport infrastructure requires properly designed Quality of Service (QoS) implementation to ensure the required level of service for all three traffic types. In addition to understanding how to configure Cisco Catalyst switches to support these services, you are also expected to understand how to troubleshoot switch configurations that may affect these services. The TSHOOT certification exam objectives covered in this chapter are:
- Troubleshoot switch support of advanced services (i.e., Wireless, VOIP and Video)
- Troubleshoot a VoIP support solution
- Troubleshoot a video support solution
Cisco IP Telephony solutions are an integral component of Cisco Unified Communications. The Cisco Unified Communications solution allows for the integration of voice, video, data, and mobile applications on fixed and mobile networks. Cisco IP Telephony solutions are comprised of call processing solutions, such as Cisco Unified Communications Manager and IP phones.
Cisco Unified Video Advantage enhances the existing Cisco IP Telephony solution by providing video telephony functionality to certain Cisco Unified IP phones. The Cisco Unified Videoconferencing solution allows for a wide range of customized as well as fully converged voice, video, and data solutions. This chapter will be divided into the following sections:
