Configuring a Routed Port

The purpose of a switch routed port is to enable the switch to perform layer 3 routing functions, allowing it to route traffic between different subnets or VLANs. It provides a point of connectivity for routing protocols and allows the switch to act as a router, providing inter-VLAN routing within the network infrastructure. This allows for more efficient and scalable network designs as it reduces the need for separate physical routers.

To change the port on your router, you need to access the router's administration page. Here are the general steps to follow:

1. Connect your computer to the router using an ethernet cable or join the router's network wirelessly.
2. Open a web browser and enter the router's IP address in the address bar. The default IP address is generally printed on a sticker at the back or bottom of the router. Common IP addresses are 192.168.0.1, 192.168.1.1, or 192.168.2.1.
3. Press Enter to access the router's administration page.
4. Enter the username and password to log in. If you haven't changed these before, try using the default login credentials; they are typically mentioned in the router's user manual or on the manufacturer's website.
5. Once logged in, navigate to the settings or port forwarding section of the router's administration page.
6. Look for an option to change or configure the ports. The specific location and wording may vary depending on the router manufacturer and model.
7. Enter the desired port number or range of ports for the specific application or service you want to change.
8. Save the changes and restart the router for the new port configuration to take effect.Remember that changing ports on your router can have implications on network performance or security, so ensure you understand the specific requirements and consequences before making any changes.

1. Log into the switch using a terminal emulation program like PuTTY.
2. Enter privilege mode by typing "enable"
3. Type "config t" to enter global configuration mode
4. Configure an interface by typing "interface [interface_number]"
5. Set the interface to become a routed port by typing "no switchport"
6. Configure the IP address of the interface by typing "ip address [ip_address] [subnet_mask]"
7. Enable the interface by typing "no shutdown"
8. Save the configuration changes by typing "write memory"

1. Connect the router's interface to the physical network.
2. Assign an IP address to the interface:interface fastethernet 0/1 ip address 192.168.1.1 255.255.255.
3. 0 Configure a subnet mask associated with the IP address:mask 255.255.255.
4. 0 Activate the interface:no shutdown
5. Configure the interface as a routed port:ip routing
6. Save the configuration:wr mem

1. Log into the Cisco router using the command line interface (CLI).
2. Enter the global configuration mode by typing the command, configure terminal.
3. Create a routed port for the router with the interface command. For example, interface FastEthernet0/0.
4. Assign an IP address to the routed port. To do this, type the command ip address [IP address] [subnet mask].
5. Assign a description to the routed port by typing the command description [description].
6. Enable the routed port. To do this, type the command no shutdown.
7. Exit the global configuration mode by typing the command end.
8. Test the connection by using the ping command.

1. Open Cisco Packet Tracer.
2. Add a router to the workspace. To do this, click on the router icon on the left side of the window.
3. Place the router in the workspace by dragging and dropping it into the desired location.
4. Right-click on the router and select “Configure”.
5. In the “Router Configuration” window, select the “Interfaces” tab.
6. In the “Interface Configuration” window, select the specific interface and click on the “IP Address” tab.
7. Enter the desired IP address and subnet mask for this interface and click on “Apply”.
8. The assigned IP address is now configured for this interface.

Switch IP addresses can be found a few different ways.

1. Access the command line by connecting your computer directly to the switch with an Ethernet cable and then typing in the command “show ip int brief”. This command will display the switch IP, mask and any other IPs assigned to the switch.
2. Access the command line by connecting to the switch over Telnet or SSH and then typing in the command “show ip int brief”.
3. Use the “show cdp neighbors” command to find the IP address of the switch if it is connected to another device or switch.
4. Access the web-based GUI of the switch and navigate to the “Device Management” page, which will display the switch IP address.

1. Connect the switch to your network: To begin, connect the switch to your network by connecting an Ethernet cable from a router to a port on the switch.
2. Configure basic settings: To configure the basic settings, you will need to open a command line interface (CLI). Through the CLI, you can enter the basic settings, including the hostname, IP address, default gateway, and Subnet Mask.
3. Configure VLANs: VLANs (Virtual Local Area Networks) help you segment your network into different subnetworks. To configure VLANs, you will need to enter a command to define each VLAN and assign ports to them.
4. Configure Spanning Tree Protocol: Spanning Tree Protocol (STP) helps prevent loops in your network by shutting down redundant links. To configure STP, you will need to enter the required commands.
5. Configure Port Security: Port security helps you ensure that only authorized users have access to specific ports. To configure port security, you will need to enable port security and enter command to specify the MAC addresses that are allowed to access a particular port.
6. Enable inter-VLAN routing: If you need to send traffic between different VLANs, you will need to enable inter-VLAN routing. To do this, you will need to enter a command in the CLI that enables the router to route traffic between different VLANs.
7. Save and Verify the Configuration: After you have entered all the required commands, you will need to save the configuration using the “write” command. To verify that everything has been configured correctly, you can use the “show” command to view the settings.

1. Configure IP Routing protocols on the router, such as RIP, EIGRP, or OSPF.
2. Configure the router interfaces with IP addresses and masks and add them to the corresponding routing protocols.
3. Configure routing protocol authentication, if needed.
4. Connect the router to the switches and configure the switch ports as trunk ports.
5. Configure the VLANs on the switches and assign each VLAN to the appropriate trunk links.
6. Configure IP addressing for each VLAN on the switches and apply the corresponding IP subnets to the trunk links.
7. Configure the router to advertise the connected VLAN networks through the routing protocols to the other switches.

1. Set up the switch's IP address, subnet mask, and default gateway.

To configure ports with IP addresses on a switch, you need to use the commands "int {number}" and "ip address {address} {subnet mask}" respectively. For example, if you want to configure port number 2 with the IP address 192.168.1.2 and the subnet mask 255.255.255.0, you would use the following commands:

The "no switchport" command in Cisco is used to remove a layer 2 switchport configuration and enable layer 3 routing on a Cisco switch interface. This command is typically used on a Layer 2 switch interface to convert it into a Layer 3 interface or a routed interface. To write the "no switchport" command on a Cisco switch, you need to enter global configuration mode and then interface configuration mode for the specific interface. Here are the steps to write the command:

1. Enter privileged EXEC mode on the switch by typing:`enable`
2. Enter global configuration mode by typing:`configure terminal`
3. Identify the interface where you want to configure the "no switchport" command. For example, if you want to configure it on interface GigabitEthernet1/0/1, type:`interface GigabitEthernet1/0/
4. 1`
5. Enter interface configuration mode for the specific interface by typing:`interface configuration`
6. Write the "no switchport" command:`no switchport`
7. To exit the interface configuration mode, type:`exit`
8. To exit global configuration mode, type:`exit` Make sure to save your configuration by typing `write memory` or `copy running-config startup-config`, so the changes are saved and applied after a reboot.

To make a MLS (Multilayer Switch) port act as a routed port, you need to use the "no switchport" command on that particular interface. This command removes the layer 2 switchport functionality and converts the port into a layer 3 routed port. Here is the command syntax: ``` switch(config)# interface <port_number> switch(config-if)# no switchport ``` Replace `<port_number>` with the corresponding interface number you wish to convert to a routed port.
