In this article I have described how inter-vlan routing is configured on Layer 3 switches. This post will deal with creating Layer 2 VLANs on Cisco switches and performing all relevant configurations. Up to 4094 VLANs can be configured on Cisco catalyst switches.

Jun 22, 2009 · This document provides basic information on how to create VLANs on Catalyst switches that run Catalyst OS (CatOS) and Cisco IOS System Software. VLANs are created by number. The two ranges of VLANs are as follows: 1) The standard range consists of VLANs 1 to 1000. 2) The extended range consists of VLANs 1025 to 4096.

switch(config)# vlan 5 switch(config-vlan)# Places you into the VLAN configuration submode. This submode allows you to name, set the state, disable, and shut down the VLAN or range of VLANs.

With Cisco IOS Release 12.2(25)EW and later, Catalyst 4500 series switches support 4096 VLANs in compliance with the IEEE 802.1Q standard. These VLANs are organized into three ranges: reserved, normal, and extended. Some of these VLANs are propagated to other switches in the network when you use the VLAN Trunking Protocol (VTP).

Feb 15, 2020 · This article provides instructions on how to configure an interface VLAN as an access or trunk port on your switch through the CLI.

Mar 20, 2025 · This tutorial explains VLAN configuration commands. Learn how to configure, test, and verify VLANs on Cisco switches.

Apr 23, 2024 · To configure VLANs we have to go to the switch Switch0 and move to Config → SWITCHING → VLAN Database. Now let us take the VLAN Number for STUDENT is 150 and for FACULTY is 250 and add these numbers to VLAN Database.

Dec 23, 2024 · In this lesson, I will explain how to configure, manage, and troubleshoot VLANs (Virtual Local Area Networks) on Cisco switches. VLANs are fundamental to network segmentation and security, allowing you to create logical network boundaries within a physical switch infrastructure. After completing this lesson, you will be able to:

Mar 3, 2025 · Switch ports don’t magically know which VLAN they belong to. This step tells the switch which ports are part of Sales (VLAN 10) and which belong to HR (VLAN 20). Assign IP addresses and default gateways to the PCs: Checking for duplicate address... Why this step?

Mar 27, 2011 · With VLAN’s, a switch can create the broadcast domain. This works by, you, the administrator, putting some switch ports in a VLAN other than 1, the default VLAN. All ports in a single VLAN are in a single broadcast domain.
