The question is this: how to simulate a real host in a physical network environment when you don’t have computer at your disposal? Well, let’s take an example.

100Gb Ethernet transceivers, modules and form factors on Cisco products

At the time of the 400Gb Ethernet interfaces introduction, here is a summary of the different form-factors, transceivers and modules available for 100Gb Ethernet on Cisco devices.

As you will see below, there are many different types of 100Gb Ethernet transceivers. And each type have its own functional mode. In a next article, I will try to explain the differences between them and will give more details about the most common: the QSFP-28.

Multicast lab 5: Source-Specific Multicast (SSM)

After giving a two-days training to a customer on multicast technology, I take the opportunity to have my lab and the configurations ready to share with you a suite of five different multicast configurations examples. And, how to make some tests and troubleshooting. These examples are based on the labs I used to practice the CCIE R&S practical exam.
