Don't Forget to tune into my Load-Balancing with PVST+ webinar tomorrow morning! When it comes to the Spanning-Tree Protocol, many people understand the basic concepts such as Root Bridge election, Root Ports and Designated Ports…and that’s it. But what happens when you have several VLANs, all of which have converged to the same Spanning-Tree topology? This can easily cause link congestion, packet latency and even dropped packets. Do you have the knowledge and skillset to adjust Spanning-Tree... Read More

OSPF Route Poisoning Techniques When first learning about IGP Routing Protocols, much time is spent learning about how routers form neighborships (if they do at all) and how new routing updates are exchanged. Little, if any, time is spent describing the process by which routers inform each other of prefixes that have gone down, and the mechanics involved in doing so. This blog post seeks to rectify that situation with regards to the OSPFv2 Routing Protocol. Every standardized routing protocol... Read More

In the world of network monitoring, SPAN and RSPAN are useful features that can be implemented on Cisco switches. These two features provide the ability to transparently monitor (by copying) select ingress traffic, while allowing the switch to continue to forward the original traffic as normal. Both SPAN and RSPAN require the selection of one-or-more SPAN Source ports (typically physical interfaces, but entire VLANs can also be selected) as well as one-or-more SPAN Destination ports (where...
