Managing Cisco Webex QoS with LiveNX

Cisco Webex (Webex) is a cloud-based, on-demand collaboration, online meeting, web and video conferencing service. While Webex is a simple application to use, protecting its voice and video call quality across the enterprise network can be challenging to manage. Fortunately, a network administrator can effectively implement Webex QoS protection by leveraging LiveAction’s application-aware network performance management platform, LiveNX, with QoS control tools.

Cisco Webex and LiveAction

LiveNX is an award-winning network performance management solution with patented visualization capabilities that utilize Cisco’s advanced IOS features to help implement management controls through its console. It provides a complete management solution for monitoring, troubleshooting and provisioning Webex QoS to ensure that bandwidth is properly allocated to support the needs of the business. Users can take advantage of LiveNX to go back in time (think ‘network DVR’) and perform analysis and troubleshooting for real-time or historic Webex calls using the Medianet Performance Monitor Path Analysis feature. Protecting critical Webex traffic throughout the managed network can easily be done with LiveNX. This document will cover the following simple steps:

  • How to use LiveNX to identify Webex traffic
  • How to use LiveNX to implement QoS markings on Webex traffic
  • How to use LiveNX to prioritize Webex traffic at the WAN edge and Internet perimeter via QoS policy
  • How to use LiveNX to monitor performance of Webex

By using NBAR2 (protocol pack 28 or higher), Cisco’s next generation network-based application recognition technology built into IOS, Webex QoS management can be further simplified to uniquely identify Webex communication without having to configure and manage complex access control lists (ACLs) in the network infrastructure. This can translate to 50 percent faster (or higher) QoS deployments and reduce the chance of mistakes during configuration. LiveAction highly recommends updating to this protocol pack to simplify Webex QoS deployments. (See Appendix D for further details.)
