There are many interesting new issues that seem to have come with the addition of voice and video to the data network. Most of the engineers that are now working on VoIP networks come from either a pure data network background or a traditional phone system background...
In my last post, we learned that the Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts, identified as DHCP clients, to retrieve IP address assignments and other configuration information. DHCP uses a client-server architectur...
Part 11 of this blog series looked at Class Based Weighted Fair Queuing. This blog will explore the next queue mechanism; Low Latency Queuing (LLQ). As seen in the previous section of this QoS series, CBWFQ provides user defined traffic classes allowing for more con...
Part 10 of this blog series looked at Weighted Fair Queuing, so now we move on to the next queue mechanism; Class Based Weighted Fair Queuing (CBWFQ).CBWFQ provides user defined traffic classes allowing for more control and functionality then weighted Fair Queuing. C...
I recently was presented with the challenge of logging ALL of the pertinent connection, disconnection, and termination messages associated with the Cisco SSL AnyConnect client without overwhelming the syslog capture display with extraneous messages. This blog will br...

Subnetting is a complicated topic that has confused students for a very long time. However, subnetting is an important topic for many different certifications with various vendors, including Cisco. In the real world environment, people are used to just punching in the numbers in many of the free subnet calculators that are readily available on the internet. For exam purposes, you still have to do this in a very fast manner since many exams are time-based and you don't have the luxury of spending those precious minutes on any single question. This Cisco training whitepaper will solve some of those age-old and complicated subnetting puzzles.
In part 8 of this blog series congestion management and its four main queuing methods were explored. This post will look at the first of four queuing methods: First In First Out (FIFO) queuing. To refresh our memories, congestion can occur anywhere within a network,...
In light of the recent tragic events in Haiti, it might be a good time to review some of the requirements for a well designed Uninterruptible Power Source (UPS) to be included in all of our critical network installations. As a CCNA, we are called upon to help maintai...
