You can change the management IP of a Huijue fiber optic switch via the console, web interface, or service interface by configuring a new IP address on the management port or VLAN interface.

Step 1: Access the Switch

To modify the management IP, first connect to the switch using one of the following methods:

• Console port: Connect a PC to the switch console using a console cable and terminal software (e.g., HyperTerminal, PuTTY) with parameters: 115200 baud rate, 8 data bits, no parity, 1 stop bit .
• Mini USB port: If no console port is available, use a mini USB cable for initial login .
• Web interface: If the switch is already reachable, log in using the current management IP via a browser .

Step 2: Determine the Management Interface

Huijue switches typically allow configuration on:

• Ethernet management port: Directly assign an IP address.
• Service interface: If the interface is in Layer 3 mode, assign an IP directly; if in Layer 2 mode, assign the IP to the VLANIF interface of the VLAN associated with the service interface .

Step 3: Configure the New IP Address

1. Enter configuration mode on the switch:

   configure terminal

2. For an Ethernet management port (e.g., MEth 0/0/1):

   interface MEth 0/0/1ip address <new-ip-address> <subnet-mask>

3. For a service interface in Layer 3 mode:

   interface GigabitEthernet0/0/1undo portswitchip address <new-ip-address> <subnet-mask>

4. For a VLANIF interface (if the service interface is in Layer 2 mode):

   interface VLANIF <vlan-id>ip address <new-ip-address> <subnet-mask>

Step 4: Configure Default Gateway (if needed)

Set the default gateway to ensure remote management access:

ip route-static 0.0.0.0 0.0.0.0 <gateway-ip>

Step 5: Verify the Configuration

• Use the command:

display ip interface brief

to confirm the new management IP is active.

• Test connectivity by pinging the new IP from a PC on the same network.

Step 6: Save the Configuration

Ensure the new IP persists after reboot:

save

Additional Notes

• If the switch supports Layer 3 routing, ensure the management IP is on the correct VLAN or interface to avoid access issues .
• For initial setup or if remote access fails, always use out-of-band management via console or mini USB .
• Some switches allow dynamic IP assignment via DHCP, but for stable management, a static IP is recommended . By following these steps, you can successfully change the management IP of a Huijue fiber optic switch and maintain reliable remote access.
