For spare switches, make sure to delete the flash:vlan.dat file to erase the previous configuration. Shows the RPS status. The Mode button is used to toggle through port status, port duplex, port speed, and PoE (if supported) status of the port LEDs. If the LED is green, the system is operating normally. Configure your switch: Connect a computer to the switch using the IP address found in the switch manual. How to configure SSH (Secure Shell) in Cisco Router or Switch for secure remote access. To do this, you will need to download and install Putty (or a similar, fun-named software tool). Knowing how switches normally boot and load an operating system is also important. Step 4. The boot loader can be accessed through a console connection using these steps: Step 1. Navigate to the Setup -> Basic Setup tab to get started. As shown in Table 2-2, the interface vlan 99 command is used to enter interface configuration mode. Be it network reorganization or brand new installation, it’s important to configure the switch properly. > Configure the Management Interface. If you want to configure either a router or switch to retrieve its IP configuration information from a network Dynamic Host Configuration Protocol (DHCP) server, then you can commands like the following example. The ip address command is used to configure the IP address. Step 5. If the LED is amber, the system is receiving power but is not functioning properly. You will get the initial command prompt “ Switch> ” Type “ enable ” and hit enter. Creates a trunk link if the neighboring interface is … If the LED is off, it indicates the PoE mode is not selected and none of the ports have been denied power or placed in a fault condition. Each device has a unique IP address. Computers are connected to a switch with Ethernet cables. As your virtual training wheels, we've broken down the task into its simplest parts so you can successfully create client VLANS, build DHCP systems, and assign access ports without skinning your knees. Just like riding a bicycle, nobody's born knowing how to setup a network switch. Learn how to make the right decisions for designing and maintaining your network so it can help your business thrive. If you have not set the console line yet, you can easily input these values: Set the enable password using the enable secret password command. Figure 2-2 Directory Listing in Boot Loader. Next, the switch loads the boot loader software. It means there is no other encapsulation supported so there is no need for an encapsulation command. All rights reserved. The switch will forward IP packets with destination IP addresses outside the local network to the default gateway. As shown in Table 2-3 and, To configure the default gateway for the switch, use the, Part 1: Cable the Network and Verify the Default Switch Configuration, Part 2: Configure Basic Network Device Settings, Part 3: Verify and Test Network Connectivity. A networking switch. Verify SSH access by typing ‘sh ip ssh’ to confirm that the SSH is enabled. If the LED is off, there is no link, or the port was administratively shut down. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button. The default gateway is the first Layer 3 device (such as a router) on the same management VLAN network to which the switch connects. First, the switch loads a power-on self-test (POST) program stored in ROM. Switches of different models and feature sets will have different LEDs, and their placement on the front panel of the switch may also vary. Configure a network adapter on the PC to be on the 192.168.0.x subnet. This mode is know as privileged EXEC mode. The switch does not have DHCP enabled by default so you will need to manually enter your IP address in your computer. Configure the management interface IP address. Step 1: First step in configuring SSH to securely access the CLI interface of a Cisco Router or Switch remotely is to create a local user database for user authentication. Cisco Network Technology When selected, the port LEDs will display colors with different meanings. If not, simply type switchport mode trunk. Specify the port to use: interface Configure the port as a Layer 2 trunk: switchport mode {dynamic {auto | desirable} | trunk} These options mean: dynamic auto – The Default. To easily reset the domain back to zero, change the config mode to transparent: You might already have a template ready for access port configuration, but in case you don’t, here are some commands you should use: Enter the command sh int g0/1 capabilities and check the trunking protocol supported. Configure the VLANs: If possible, decide which port goes to which VLAN (virtual local area networking), and configure the switch … If the LED is blinking green, there is activity and the port is sending or receiving data. Enter interface configuration mode for the SVI. Objective. Next, use a rollover cable to console into the switch from your computer. The SVI is a virtual interface, not a physical port on the switch. Step 1. If the port LED is green, PoE is being provided to a device. Next, make sure your switch has a set hostname and domain name: Hit the show vtp status command to reveal your Virtual Trunking Protocol (VTP) revision numbers. It only supports 802.1Q. Access your router settings by inputting your router IP address into your browser Log in with router username and password Visit “Guest Network” and make sure the “Enable SSID Broadcast” check box is ticked Name the guest network and select a security option, then click “apply” to save the settings Cisco Networking Academy's Introduction to Basic Switching Concepts and Configuration, Routing and Switching Essentials Companion Guide. The boot loader performs low-level CPU initialization. To create a VLAN with the vlan_id of 99 and associate it to an interface, use the following commands: The SVI for VLAN 99 will not appear as “up/up” until VLAN 99 is created, the IP address assigned to the SVI, the no shutdown command entered, and either (1) a device is connected to an access port associated with VLAN 99 (not a best practice) or (2) a trunk link (covered in the VLAN chapter) connects to another network device such as a switch. Check the model number of your shiny new switch. Indicates the port duplex mode is selected when the LED is green. ⭐ How to configure a trunk port on a Cisco 2960 switch? Step 2: Connect your modem to the telephone wire. Keep in mind that to manage the switch from a remote network, the switch must be configured with a default gateway. After a Cisco switch is powered on, it goes through the following boot sequence: Step 1. On Catalyst 2960 Series switches, the image file is normally contained in a directory that has the same name as the image file (excluding the .bin file extension). To prepare a switch for remote management access, the switch must be configured with an IP address and a subnet mask. The VTP revision numbers determine which updates are to be used in a VTP domain. Step 1: Use an external emulator such as Telnet or a PuTTY to login to the switch. If the port LED is green, the port is in full-duplex mode. In the Basic Setup tab, ensure the following settings are adjusted. If this variable is not set, the switch attempts to load and execute the first executable file it can by performing a recursive, depth-first search throughout the flash file system. If PoE is supported, a PoE mode LED will be present. Configurations and settings applied to a VLAN are also applied to all the ports assigned to that VLAN. Initial command prompt " Switch> " appears on the screen. And this process is a little more advanced than, say, setting up your home Internet or even a plug-and-play type switch. The switch does not need to be plugged into other network device such as a router until the initial configuration is completed. Keep in mind that to manage the switch from a remote network, the switch must be configured with a default gateway. Our resources are here to help you understand the security landscape and choose technologies to help safeguard your business. Then, set the privilege exec password with username name privilege 15 secret password. With this greater control, you can better protect your network and improve the quality of service for those who access the network. Configuration of both is simple, usually varying minimally from switch to switch and even from brand to brand. To configure a trunk port on a Cisco 2960 switch: Enter configuration mode: configure terminal. Therefore, you must use Telnet to configure the Switch with a remote connection from a PC on the network. In a depth-first search of a directory, each encountered subdirectory is completely searched before continuing the search in the original directory. Home Use a terminal emulation software such as PuTTY and connect to the console of the switch. S1(config-if)# ip address 172.17.99.11 255.255.0.0. SVI is a concept related to VLANs. assign an IP address with the ip address IP_ADDRESS SUBNET_MASK interface subcommand. Indicates the port speed mode is selected. Steps to Set up a Network Switch With a Router. > These tools and articles will help you make important communications decisions to help your business scale and stay connected. What You Need While Setting up LAN Network: Cable router, Crossover Ethernet cables, Ethernet cables, Ethernet switch, Network interfaces. Power on the computer closest to the modem. Configuring them can be fun and challenging. After that, connect one end of an Ethernet cable to the Ethernet port on the back of the modem. Instructions to Set Up LAN Network. Both interfaces are now “up/up” and operational. The no shutdown command enables the interface. If the LED is blinking amber, PoE is off due to a fault. There you'll find answers to common questions and connect with people running similar businesses and facing similar IT challenges. You are now connected to the switch and ready to check the output of the following commands: For spare switches, make sure to delete the flash:vlan.dat file to erase the previous configuration. Open the putty and you can try the following basic configurations for console connection to your Switch. Do not make changes to an Enterprise network or networks managed by others without proper authorization. This is how to configure VLAN on Cisco Switch or Virtual LAN on Cisco Switches in your network. If the LED is blinking amber, the PoE mode is not selected but at least one of the ports has been denied power, or has a PoE fault. Choosing a key modulus greater than 512 may take a few minutes. If the LED is green, a link is present. Access the command prompt of the switch and run the following commands. IOS is a group of commands used for monitoring, configuring and maintaining cisco devices.

Router1> enable Router1# configure terminal Router1 (config)# interface FastEthernet0/0 Router1 (config-if)# ip dhcp To start using your Smart Switch for the first time: Install the Smart Control Center Utility on a computer with a network card. In this example, VLAN 99 is configured with the IP address and mask of 172.17.99.11. All ports are assigned to VLAN 1 by default. Save the running config to the startup config. Connect the switch to a LAN port on the router. This means that the switches will update their VLAN configuration based on the VTP information being sent by the switch with the highest revision number. It connects linked devices and allows you to monitor the network traffic information. All that’s left is to test your access, reload the switch, and ready the cables. Once that’s done, label your switch, rack it up, and go enjoy doing anything that doesn’t involve switch configuration! An IP address and subnet mask is configured on the management SVI of the switch from VLAN interface configuration mode. The following image shows this network. The boot loader initializes the flash file system on the system board. Make sure that the password-encryption service is activated. In this lab, you will complete the following objectives: © 2021 Pearson Education, Cisco Press. After already performing basic network switch configurations, it’s time to generate RSA keys to be used during the SSH process, using the crypto commands shown here: Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Run Putty and select the 9600 speed serial connection. The boot loader command line supports commands to format the flash file system, reinstall the operating system software, and recover from a lost or forgotten password. Your switch will only process data from a neighboring switch coming from the same domain and if the revision number of the neighboring switch is higher than its own. Managed switches give you greater security and more features and flexibility because you can configure them to custom-fit your network. The main function of managed switches is, obviously, dividing a core network into smaller subnets. Here are the steps to configure an IP address under VLAN 1: enter the VLAN 1 configuration mode with the interface vlan 1 global configuration command. enable the VLAN 1 interface with the … Step 3. Articles Make If the LED is alternating green-amber, there is a link fault. Use the show bootvar command (show boot in older IOS versions) to see the current IOS boot file version. The cluster network provides connectivity between multiple Data ONTAP 8 Cluster-Mode nodes that have been configured to operate in a cluster. Cisco Networking Academy's Introduction to Basic Switching Concepts and Configuration, Switch Security: Management and Implementation (2.2), Cisco Programmable Fabric Using VXLAN with BGP EVPN, Trunking Mechanics of Cisco Network Switches, The switch should be configured with a default gateway if the switch will be managed remotely from networks not directly connected. 1. Managed switches. For instance, sorting user computers by departments or positions (accounting, sales, logistics, etc.). VLAN is a function that allows dividing a physical network into several virtual subnets, so that one subnet will correspond to a definite VLAN. Unlike with that punny name you gave your home Wi-Fi network, when setting up the hostname for your switch you should probably stick to a more professional and standard naming convention. When selected, port LEDs that are off are in half-duplex mode. Figure 2-4 Preparing for Remote Switch Management. Most switches offer two primary means of sending this data to a central repository: logging events via syslog and trap events via SNMP ((Simple Network Management Protocol). Click Switch1 and click CLI menu item and press Enter Key Navigating between different switch command modes Cisco switches run on proprietary OS known as Cisco IOS. The IOS operating system then initializes the interfaces using the Cisco IOS commands found in the configuration file, startup configuration, which is stored in NVRAM. For security purposes, it is considered a best practice to use a VLAN other than VLAN 1 for the management VLAN. Step 4. If the LED is blinking green, the RPS is connected but is unavailable because it is providing power to another device. Figure 2-3 shows the switch LEDs and the Mode button for a Cisco Catalyst 2960 switch. > POST checks the CPU subsystem. Finally, the boot loader locates and loads a default IOS operating system software image into memory and hands control of the switch over to the IOS. Hook the Wi-Fi router up to the network via one of the LAN ports (later you can switch the cable to the WAN port). Step 3. The boot loader is a small program stored in ROM and is run immediately after POST successfully completes. You can use the switch LEDs to quickly monitor switch activity and its performance. If you're using a network switch to connect more computers, connect it to one of the LAN ports on the router. The boot loader switch: prompt appears in the terminal emulation software on the PC. Or, if you are using a spare, check the device hardware and its connected cables for any damages. Configure your switch: Connect a computer to the switch using the IP address found in the switch manual. To begin configuring the switch, first plug a desktop or laptop computer into any port in the switch. For example, the dir command can be used to view a list of files within a specified directory as shown in Figure 2-2. Configuring DHCP service on the switch. When selected, the port LEDs will display colors with different meanings. You’ve made it through the learning process with (hopefully) minimum bumps and bruises, and you’re just about ready to ride off. Step 1: Unplug all the power supplies of cable modem, network switch and wireless router. This article describes setup and configuration best practices for the management and monitoring of Cisco Nexus 50x0 switches deployed as NetApp cluster network switches. Connect a console cable from the PC to the switch console port. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. In Figure 2-4, the switch virtual interface (SVI) on S1 should be assigned an IP address. VLANs are numbered logical groups to which physical ports can be assigned.
