Configure IP address for optical switch

To configure an IP address on an optical switch, assign it to a management VLAN interface, enable the interface, and optionally set a default gateway for network access.

Step-by-

Step Configuration1.

Access the Switch CL

I Connect to the switch using a serial console cable, SSH, or Telnet. Log in with your credentials. If using default settings, the username and password may be something like cisco/cisco.

2.

Enter Privileged EXEC Mode At the CL

I prompt, enter enable and provide the enable password to access privileged mode. 3. Enter Global Configuration Mode Use the command configure terminal to enter global configuration mode.

4. Select the Management Interface (VLAN) Most switches use VLAN 1 as the default management VLAN. Enter interface configuration mode with: CodeCopyinterface vlan 1 If your network uses a different VLAN for management, replace 1 with the appropriate VLAN ID.

5.

Assign the I

P Address and Subnet Mask Set a static IP address with the command: CodeCopyip address For example: CodeCopyip address 192. 168. 1.

10 255. 255. 255.

0 Optionally, you can also specify a default gateway for the switch to communicate outside its subnet: CodeCopyip default-gateway For example: CodeCopyip default-gateway 192. 168. 1.

1 This step ensures the switch can be managed remotely across different subnets. 6.

Enable the VLA

N Interface Activate the interface using: CodeCopyno shutdown This brings the VLAN interface online so the IP address is active. 7. Save the Configuration Exit interface mode and save the configuration to prevent loss after a reboot: CodeCopyendwrite memory orCodeCopycopy running-config startup-config This ensures the IP settings persist.

8.

Verify the Configuration Check the I

P address assignment and interface status with: CodeCopyshow running-configshow ip interface briefping This confirms the switch is reachable and the IP address is correctly configured. Additional ConsiderationsDHCP vs Static IP: If a DHCP server is available, the switch can automatically obtain an IP address. For stacked switches or critical management interfaces, a static IP is recommended to avoid address changes during failover.

VLA

N Selection: Ensure the management VLAN is properly configured and not blocked by access control lists or port security. Maintenance Window: Changing the management IP may temporarily disrupt connectivity, so perform this during a maintenance window. By following these steps, you can successfully configure an IP address on an optical switch, enabling remote management and network monitoring.
