VTP Modes of Operation – How VTP Works.

VTP has three different modes of operation within a domain: Server, Client and transparent. VLANs Trunking Protocol – VTP uses advertisements to communicate VLAN information between switches in a network. When a switch is configured as a VTP server, it can create, modify, and delete VLANs, which are then propagated to other switches in the same VTP domain.… Read More »

VTP Pruning Explained with Examples.

What is VTP Pruning? VTP (VLAN Trunking Protocol) pruning is a feature in Cisco network switches that optimizes the use of bandwidth by reducing unnecessary traffic related to VLANs (Virtual Local Area Networks). Simply put, it is a technique for controlling the distribution of VLAN details throughout a network.This technique helps to ensure that VLAN configurations are consistent… Read More »

Troubleshooting EtherChannel Explained.

If you had been studying EtherChannel; you will understand that it is a port link aggregation technology developed by Cisco, used primarily in networking to combine multiple physical Ethernet links into a single logical link. This aggregation method enhances the bandwidth and reliability of the network connection. Here are key aspects of EtherChannel: Bandwidth Improvement: By combining, for… Read More »

Troubleshooting VLAN Trunk Modes Mismatch Example.

Error#2. How to Troubleshoot Trunk Mode Mismatches Trunk mode mismatches in networking occur when there is a configuration inconsistency between network devices (like switches) connected through a trunk link. A trunk link is used to pass traffic from multiple VLANs across network devices. Understanding trunk mode mismatches requires a grasp of a few key concepts: Trunk Mode: In… Read More »

Troubleshooting VTP: Server as Client error and Solution.

Error Setting Server Switch as VTP Client Solution. Mistake happens,  As a network administrator, you can mistakenly configure the operating mode of the server switch as a VTP client. Only Server switches can create, delete, and modify VLANs. By reconfiguring the sever switch to VTP client mode, you lose all ability to create, delete, and manage VLANs within your network… Read More »
