While I was testing some new Remote Labs for a renewed CCNP curriculum (for a TSHOOT course, to be precise), I came across a very interesting but undocumented command that turns a router into a traffic generator. Even though this command was introduced awhile ago, in IOS version 11.2, please keep in mind that such activity heavily utilizes even a modern router’s CPUs, and its use should be avoided in production networks unless you’re performing stress tests. If you’re looking for a way to perform regular measures of bandwidth availability in your production network, look for a solution like Bandwidth Monitor.

Whether you are delivering a pitch to potential customers or upper management, or you find yourself in front of a dozen students while lecturing in a Cisco course, there is a good chance that you’re using PowerPoint slides for your presentation. While your audience can normally observe the slide show on a large plasma TV or as a projected picture on a table or an empty wall, usually you’re the only one who is able to see your computer screen. Instead of displaying exactly the same content on your monitor as your audience sees, take advantage of having your own “private” screen, and display the relevant information you need as a speaker, rather than as a spectator.

In recent weeks, I have participated in a few WebEx conferences. While those organized by Cisco mostly relied on traditional telephone connections for audio delivery, others used an integrated VoIP solution, which has a more attractive price.
While good old telephony works pretty well no matter where you are or what you are doing, this is not always the case with voice-over-IP (VoIP) solutions, and WebEx is no exception.
It is pretty obvious that the host of the session needs a decent Internet connection to enable all participants to experience a satisfying level of quality. Things start to get more complicated when a few participants are having audio problems and cannot hear the presenter clearly, while other users don’t experience any audio problems. This was the case for Ivan Pepelnjak recently, while he was delivering one of his new seminars.

NIL has developed a policy management server that enables service providers using the Cisco Service Control Engine (SCE) to monitor and control subscribers and their quotas on SCE devices. For each subscriber, the policy management server maintains the quota amount and keeps track of quota usage. Each subscriber’s quota is maintained based on the subscriber’s assigned subscription plan (package). Periodically — for example, monthly or weekly — the quota can be replenished automatically, based on the service provider’s policy.

The jungle of acronyms – from 2G (GSM, GPRS, EDGE) through 3G (UMTS) toward 4G (LTE), interleaved with Wi-Fi, WiMAX and similar terms – makes both potential users and specifically service providers offering first-mile wireless service rather uncomfortable. The January IP Corner article provides an overview of first-mile wireless technologies, their benefits and drawbacks, focusing on future trends in access, driven by the Video over Mobile Wireless environment.
