the most distinguish feature of layer 3 switch is its routing capability Unfortunately, in the implementation, the routing function on the switch is often not used because routing task is done by dedicated router You can save more money by using products from other vendor which produces managed switches. You can use your choice of number for the channel-group. Configuring Physical Layer 3 Interfaces To configure physical Layer 3 interfaces, perform this task: This example shows how to configure an IP address on Fast Ethernet interface 2/1: Switch# configure terminal Enter configuration commands, one per line. 2. Configure Inter-VLAN Using Layer 3 Switches. The logical Layer 3 VLAN interfaces integrate the functions of routing and bridging. We will also configure the switch port connect to the router as native Layer 3 port. A layer 3 switch is a device that forwards traffic (frames) based on layer 3 information (mainly through mac-address). Configuration - Here is a topology in which we have a layer 3 switch connected to host devices namely PC1, PC2, PC3, PC4. spanning-tree mode pvst ! End with "CNTL/Z".] One for the uplink to the Firewall (which acts as the switch's default route), one for the data VLAN, and one for the voice VLAN. In the example below, 10.0.0.4 is the FTP server, the " transfer-on-commit " tells the switch to backup the config to FTP when "commit" happens. Provide a name for the network. Configuration Notes This example uses router configurations of AR3600 V200R007C00SPCc00. Configure these interfaces as a Layer 3 Etherchannel with LACP. End with CNTL/Z. Generally, 1K = 1024 VLANs is enough for a Layer 2 switch, and the typical number of VLANs for Layer 3 switch is 4k = 4096. The physical Layer 3 interfaces allow the Catalyst 4500 series switch to be configured like a traditional router. Even if IP routing was previously enabled, this step ensures that it is activated. This configuration example shows a simple topology to illustrate how to connect a single Layer 2 access switch connected to multiple VLANs to a distribution switch, enabling traffic to pass between those VLANs. Routers on the other hand typically have a much . First to go System > Routing > Gateways and click "Add" and enter the IP address of the Layer 3 switch routed port. This article covers basic and advanced configuration of Cisco Catalyst Layer 3 switches such as the Cisco Catalyst 3560G, 3560E, 3560-X, 3750, 3750E, 3750-X, 3850 and 4500 series, and extends to include the configuration of additional features considered important to the secure and correct operation of these devices. PC1-192.168.1.10/24, PC2-192.168.1.20/24, PC3 - 192.168.2.10/24, PC4-192.168.2.20/24. Add rules to ACL 101 (for VLAN 10). Virtual routing interfaces (used by VLANs to route among one another) Loopback interfaces. PC0 is sitting in Vlan 1. Switch(config-vlan)# name Users. It requires to be as short as possible, so the . Switch (config-if)# ip address 172.16.1.1 255.255.255.252. 1. On MLS, configure interface g0/1. Unifi switches - Layer3 configuration (routing) In this tutorial, we will show in a few steps how to configure a simple Layer3 routing, based on UniFi switches. Purpose of a layer 3 switch Under Status > L3 routing status , click Configure layer 3 settings. Cisco Switch Layer2 Layer3 Design and Configuration Written By Harris Andrea Layer2 and Layer3 switches are the foundation of any network. Switching at layer 3 . Create a new network by selecting the Add New Network option. The window that appears will allow the configuring of the first routed interface and a default route. Switch#config t [Enter configuration commands, one per line. interface GigabitEthernet0/2 no switchport ip address 172.16.2.42 255.255.255.252 duplex auto Starting at '1' and using the same number on both sides keeps the configuration logical and easier to troubleshoot. interface GigabitEthernet0/1 no switchport ip address 172.16.2.18 255.255.255.252 duplex auto speed auto ! We need to issue the ip routing command to enable it from global config. For pfSense to know about the networks we need add static routes back to Layer 3 switch. For traffic passing between two VLANs, the switch routes the traffic using a Layer 3 routing interface on which you have configured the address of the IP subnet. 4. The switch won't "switch" traffic on this interface but route it. Go to Security - ACL - Advanced - IP Extended Rules. Switch(config)# interface range fa 0/1-3. Layer 3 switches were developed to provide the network with the following advantages: Better fault isolation and traffic segregation Simplify security management Reduce broadcast traffic volume Easier VLAN configuration process Support Inter-VLAN routing Separate routing tables Reduce effort and time in troubleshooting After the configuration is complete, the configuration can be verified by testing connectivity between the hosts. The switch bridges traffic within a VLAN. 3. Here is the output of some commands: AURLHRSWDN01#sh run hostname AURLHRSWDN01 ip routing ! To decide the ip addresses yes you choose - so if ISP 1 uses 192.168.1.x and the router is .1 then you could assign the switch as .2. Layer 3 switch can create and store the VLANs which breaks the big broadcast domain into small broadcast domains. Need to rerun a command? Layer 3 switch is conceived as a technology to improve network routing performance on large LANs. Below are some of the Cisco Catalyst Series switches with Layer 3 functionalities: Configure the uplink interface first using the following steps: Layer3-Switch (config-if)# no shut ! Port densityLayer 3 switches are enhanced Layer 2 switches and, hence, have the same high port densities that Layer 2 switches have. This section explains one option, an option that uses switched virtual interfaces (SVI). Switching algorithm is simple and is the same for most routed protocols. I have the following setup: SW1 - Layer 3 switch has 3 Vlans: Vlan 1 (off Fa0/2), Vlan 2 (off Fa0/3) and Vlan 3 (off Fa0/4). network layer where it route packet by using IP address, it is used widely on VLANs. Opposite to layer 2 switch a layer 3 switch use the IP address along with MAC address for forwarding the data packets in the network. Open the UniFi Network application and navigate to the Settings > Networks section. Then, enable EIGRP so that it can exchange route information with other routers. Switch(config-vlan)# exit. Follow the steps below to create a new network: 1. Layer 3 switch supports all switching features, while also has some basic routing functions to route between the VLANs. Some of these services which make a layer 3 switch better than a layer 2 Switch are. Make the interface a static trunk port. Performs on two OSI layers layer 2 and layer 3. GRE tunnels. data link layer and sends a "Frames" to destination port using MAC address table which stores the mac address of a device associated with that port. Layer 3 switches. For example, hitting tab after "conf" auto-completes to "configure": 3. Create ACL to control traffic between VLAN 10 to VLAN 20 Step 12 Click the Idle-PC Finder button to select the optimal value for your computer's processor performance for Layer 3 Switch IOS. Using Layer 3 switches for inter-VLAN routing as opposed to traditional routers is popular (and recommended) for the following reasons: Performance versus Cost. Giving IP addresses to All hosts. Layer 3 Switch Layer 3 switches provide the routing function, which indicates a network-layer function in the OSI model. I'm having trouble configuring routing between Layer 3 switch and the router. The hosts PC1, PC2 will be in Vlan 10, and PC3, PC4 will be in Vlan 20. This is used with BGP. Tab completion. On the Layer 3 switch, the trunking interface needs to be encapsulated with the dot1q protocol, however it is not necessary to specify VLAN numbers as it is when working with a router and subinterfaces. Of course, keep in mind that not all UniFi switches support hardware support for L3 routing. The Layer 3 forwarding (routing) logic forwards IP packets between VLANs. Layer 3 switch work on layer 3 of OSI model i.e. After all, any network devices (routers, firewalls, computers, servers etc) have to be connected to a switch. . b. Memory of MAC address table is the number of MAC addresses that a switch can keep, usually expressed as 8k or 128k. Set the sensitivity in detecting rapid MAC mo vement, by using the following command to tell the switch how many times a MAC address can move ports in one second: set switch thrashlimit=5..255 Configuration on trunk groups Assign an interface to the VLAN by specifying the logical . Layer 3 switch are capable to do routing of data packets in a network. How to Configure Cisco Layer 3 Switch Juniper L3 Switch configuration examples Configure automatic backup whenever there is a "commit" executed. A layer 3 etherchannel is similar to an interface on a router. Trunk configuration differs slightly on a Layer 3 switch. Step-by-Step Instructions Complete these steps in order to configure a switch to perform interVLAN routing. To configure Inter-VLAN on a Layer 3 switch, you must assign an IP address to VLANs instead of sub-interfaces. Enable routing on the switch with the ip routing command. Leave the RAM value of Layer 3 Switch as default and click Next. Switch (config)# ip routing Switch(config)# vlan 3. Switch (config)#ip routing. Create 6 routable vlans for 192.168.11./24 - 16/24 Creating VLANs console> enable console# config console (config)# vlan database console (config-vlan)# vlan 2 console (config-vlan)# exit console (config)# interface vlan 2 console (config-if)# ip address xxx.xxx.xxx.xxx console (config-if)# routing (enables routing on this vlan) Layer 3 switches typically support two configuration options to enable IPv4 routing inside the switch, specifically to enable IPv4 on switch interfaces. Layer 2 switch work on layer 2 of OSI model i.e. Configure IP address 192.168..1/30 on Switch1 and 192.168..2/30 on Switch2. Latency is the delay time that a data transfer suffers. This can be done by configuring a layer-3 switch, each with a main router in a wide area networking scenario so that the switch can manage all the local level VLAN routing. . Thank you for reading More from this site Switch#Switch#conf t. Enter configuration commands, one per line. The idea of creating Layer-3 switch is basically to efficiently do inter-VLAN routing or to do internal routing between multiple broadcast domains (multiple LAN where each LAN has its own subnet) while keeping Layer-2 features such as spanning tree and trunking. In one common topology, known as a "router on a stick . The two upstream Layer 3 interfaces connected to the spine switches are configured. step 3 - yes configure the switch ip vlan interfaces to match the ISP links. This Layer 2 switch series provides reliable, secure, and simple Ethernet access for enterprises, small and medium-sized businesses, and branch office networks. We will use ACL 102 for VLAN 20 and ACL 103 for VLAN 30. To route, the Layer 3 switch configuration uses interfaces called switched virtual interfaces (SVI), which are also called VLAN interfaces. Step 13 Configure a route map and IP prefix list to redistribute all loopback addresses and leaf networks through BGP. Step 4 ip routing and the static routes - for which you need to know the remote network information. Select the appropriate UniFi Switch in the Router field. In the ACL ID/Name drop down menu, choose 101. Before we configure the port channel settings you need to make sure that all interfaces have the exact same configuration. From a host, verify connectivity to a host in another VLAN using the ping command. End with CNTL/Z. Configuring the Layer 3 Interfaces On the Distribution Switch, three layer 3 interfaces will be required. Work the same, just need a Cisco Layer 3 switch. Each IP address on a Layer 3 switch must be in a different subnet. Repeat steps 1 - 3 to add additional ACLs 102 and 103.
