How to configure IP on an access switch

You can configure an access IP address on a switch by assigning it to a VLAN interface, either via CLI or web GUI, and optionally setting a default gateway for network management.

Using the Command Line Interface (CLI)

1. Connect to the switch Use a console cable or SSH to access the switch CLI. Log in with your credentials (default is often cisco/cisco) if not previously changed .
2. Enter Global Configuration Mode

3. Select the VLAN Interface Typically, VLAN 1 is used for management:

   CodeCopyinterface vlan 1

4. Assign the IP Address and Subnet Mask

   CodeCopyip address 192.168.1.10 255.255.255.0no shutdown

5. Configure the Default Gateway (Optional)

   CodeCopyip default-gateway Example:

   CodeCopyip default-gateway 192.168.1.1

6. Verify Configuration

Using the Web GUI

1. Access the Switch Web Interface Open a browser and enter the switch's current IP address (default may be 192.168.0.1). Log in with your credentials .
2. Navigate to VLAN or Interface Settings Go to L3 FEATURES > Interface and select VLAN 1 (or the VLAN you want to manage).
3. Change IP Address
   • Set IP Address Mode to Static.
   • Enter the new IP address and subnet mask.
   • Click Apply to save changes.
4. Configure Default Gateway (Optional) Navigate to L3 FEATURES > Static Routing > IPv4 Static Routing Config, set the destination as 0.0.0.0, subnet mask 0.0.0.0, and specify the next hop IP as your gateway. Save the settings .
5. Verify Access Open a browser and enter the new IP address to confirm you can reach the switch.

Best Practices

• Use a static IP for management VLANs to avoid IP conflicts or changes during DHCP lease renewal .
• Ensure the IP address is unique within the network.
• Save the configuration to prevent loss after reboot:

By following these steps, your switch will have a configured access IP address, enabling remote management and network monitoring.
