What is a Variable Length Subnet Mask (VLSM)? Variable Length Subnet Masking (VLSM) is a technique that enables network administrators to partition an IP address space into subnets of varying sizes, as opposed to traditional same-size Subnetting. Variable Length Subnet Mask (VLSM) in a way, means subnetting a subnet. To simplify further, VLSM is the breaking down of… Read More »
What is a Virtual Private Network? A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, mainly the internet. It is widely used for various purposes, including enhancing security, privacy, and enabling remote access to network resources. Here’s a detailed overview: Fundamental Concept: Encrypted Connection: A VPN encrypts… Read More »
VTP -Password Error VLAN Trunking Protocol (VTP) is a Cisco-developed protocol that enhances the management of VLAN configurations across a switched network. VTP allows network admins to centrally control VLAN information, which is then distributed to all switches in the VTP domain, ensuring that all switches have consistent VLAN information. VTP uses a password as a security feature… Read More »
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 »
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 »
