Here are examples of such switches:Ĭatalyst 3550/3750/6500 with Supervisor Engine 720Ĭatalyst 4500/4000 with Supervisor Engine II+, Supervisor Engine III, and Supervisor Engine IV With inter-VLAN routing, no external device, modules, or daughter cards are required.
#CISCO 2950 SWITCH CONFIGURE VLAN SOFTWARE#
Some of the switches have built-in support in software and hardware to do inter-VLAN routing. Multilayer Switch Module (MSM) or Multilayer Switch Feature Card (MSFC) for Catalyst 6500/6000 Switches Route Switch Module (RSM) or Route Switch Feature Card (RSFC) for Catalyst 5500/5000 Switches WS-X4232-Layer 3 card for Catalyst 4500/4000 Switches with Supervisor Engine I and Supervisor Engine II If you require communication between VLANs, you must use a Layer 3 routing device, such as an external Cisco router or an internal router module. If you need to have communication between VLANs, or if they are isolated Which ports on the switch belong to which VLAN What VLAN Trunk Protocol (VTP) domain name and VTP mode to use on this switch
#CISCO 2950 SWITCH CONFIGURE VLAN HOW TO#
In order to create VLANs, you must decide how to configure these items: This function is useful to reduce the size of broadcast domains or to allow groups or users to be logically grouped without the need to be physically located in the same place. VLANs are a mechanism to allow network administrators to create logical broadcast domains that can span across a single switch or multiple switches, regardless of physical proximity. Prerequisites RequirementsĬisco recommends that you have knowledge of the information in this section. The sample commands for each section use one Catalyst switch from each configuration section. This document provides basic information on how to create VLANs on Catalyst switches that run Catalyst OS (CatOS) and Cisco IOS® System Software.
