Overview by Sean Wilkins of traffic policing and traffic shaping configuration when implementing Quality of Service (QoS) on a network. Included are the main differences between traffic policing and shaping. Also explained is the token bucket mechanism.

Sean Wilkins covers AutoQoS VoIP and AutoQoS for the Enterprise, which allow for automatic quality of service (QoS) configuration on your network. While AutoQoS VoIP requires very little configuration in order to implement, AutoQoS for the Enterprise is split into two separate configuration phases: a discovery phase, and a generation & installation phase.

Digital voice port configuration on a VoIP network by Sean Wilkins, focusing on T1 and E1 voice port types. Covers emulation methods, codec complexity configuration and T1 & E1 controller configuration.

Analog voice port configuration on a VoIP network by Sean Wilkins. Includes configuration details for the three main voice port types: Foreign Exchange Office (FXO), Foreign Exchange Station (FXS), and Ear and Mouth (E&M).

Sean Wilkins discusses QoS Classification and Marking configuration in relation to VoIP Quality of Service implementation on Cisco equipment. This marking is used by devices on the network to prioritize high priority over low priority marked traffic. Also covered are Differentiated Services Code Point (DSCP) values, Per Hob Behaviors (PHB) and Modular QoS Command Line Interface (MQC).

Expanding upon VoIP Quality of Service (QoS) basics, Sean Wilkins discusses congestion management techniques and queue configuration. Includes popular queueing mechanisms like FIFO (First-In First-Out), WFQ (Weighted Fair Queueing), Priority and Custom Queueing to reduce the effect that network congestion has on the flow of traffic across the network.

Explanation of VoIP dial peer configuration options by Sean Wilkins, including different ways to utilize the dial peer functionality that is built into Cisco IOS.

Sean Wilkins covers the basic factors to take into consideration when configuring Quality of Service (QoS) with VoIP, including bandwidth, delay, jitter & loss, and the high level QoS methods available to achieve quality voice traffic.

Sean Wilkins covers wireless solutions for small and medium sized businesses (SMB), including features overview of Cisco’s current access point and wireless router products.

Sean Wilkins provides an overview of the basic concepts of voice operations as they relate to VoIP implementation and the CCNA Voice Exam.

Overview of wireless LAN technologies including 802.11 standards variations, channel planning and options for implementing Cisco Access Points.
