Virtual routing and switching simulator are grate tools to help you prepare for your CCNP exam. However we do know that there are some limitations to it, primarily the lack of switching support and quite a few useful commands. Since Cisco’s CCNP exam series is actually pretty heavy on some of these commands especially in […]
So far most of the labs provided on this site have been geared to preparing you for the CCNP routing and switching exams. These exams certify you have a complete understanding of routing and switching technologies, although to be certified as a CCNP you still need to pass the Troubleshooting and Maintaining Cisco IP Networks […]

On most Cisco switches it is possible to create logical connections that are made-up off different physical interface. It is required that these interfaces share the same speed. Most Cisco switches support a maximum of 64 EtherChannels. These interfaces do not need to be contiguous, or even within the same module. Each channel must be […]

EtherChannel is a port link aggregation technology or port-channel architecture that allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches. An EtherChannel can be created from between two to eight active Fast, Gigabit Ethernet ports; with an additional one to eight inactive (failover) […]
