What Is VLAN Hopping Attacks? VLAN hopping is a type of network attack that exploits certain properties of the VLAN (Virtual Local Area Network) setup, particularly on switches, to gain unauthorized access to traffic of other VLANs that would normally be restricted. VLANs are used to segment network traffic, with the purpose of increasing security and performance by… Read More »
What Is InterVLAN? We define inter-VLAN routing as a process of forwarding network traffic from one VLAN to another VLAN using a router or layer 3 device. A VLAN is a sub-group within a network, which partitions and isolates network traffic at the data link layer (Layer 2) of the OSI model. VLANs are used to segment networks for… Read More »
What Is Router on a Stick Inter-VLAN Routing? Router on a stick interVLAN routing is a computer networking method used for managing traffic between different VLANs (Virtual Local Area Networks) on a single physical router interface. This method is often employed in small or medium-sized networks where there is a need for inter-VLAN routing but not enough traffic… Read More »
The post describes how to configure a VLAN Trunking Protocol (VTP) on Cisco switches, detailing steps to establish trunk links, set VTP servers and clients, and authenticate with a shared domain and password.
What Is Dynamic Trunking Protocol (DTP) The Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol that is automatically enabled on Catalyst 2960 and Catalyst 3560 Series switches. DTP is used to negotiate to form a trunk link between two or more Cisco devices before actually forming the trunk connection. The main benefit of DTP is to increase… Read More »
