How to Troubleshoot Spanning-Tree Protocol

In most networks, the best Spanning-Tree Protocol topology is determined as part of the network blueprint. The Spanning-Tree Protocol is implemented by configuring Spanning-Tree Protocol priority and cost values. Several things could go wrong. You can expect something, but your switches can give you something different. Situations also occur when the Spanning-Tree Protocol was not […]

What is PVST+ Load Balancing? – Exclusive Explanation

Network load balancing is the technique to manage traffic across a network without the use of complex routing protocols such as BGP. Network Load Balancing divide load across multiple links, which use the network resources more efficiently and avoid network overload. Load balancing may be accomplished through software or hardware. Now, look at the topology […]

What is RSTP and Rapid PVST+: Exclusive Details

RSTP- IEEE 802.1w is the advanced version of STP, providing faster convergence than CST but holding with the same single root bridge in the topology. Most parameters in RSTP are the same as STP, so users who understand STP can effortlessly configure the RSTP. Rapid PVST+ is Cisco’s proprietary implementation of RSTP that operates on […]
