Using the ONS-C401i as a Standalone Switch

This article explains how to configure the ONS-C401i so that it can be managed without OneView™, as a standalone switch.

Although primarily designed to be connected to Optigo's ONS-S8 aggregation switch and managed from OneView™, the ONS-C401i can also be managed as a standalone switch with its built-in management interface.

Accessing the ONS-C401i Management Interface

1. With your ONS-C401i powered up, but connected to no other equipment, reset it to defaults by holding down the reset button for 30 seconds (NOTE: use the end of a paperclip or something similar).
   
   
2. Set up your computer's network settings as follows:
   
   IP Address = 192.168.255.100
   Subnet Mask = 255.255.255.0
   Gateway = 192.168.255.1 
   
   
3. Connect your computer's Ethernet port to port 4 on the ONS-C401i.
   
   
4. Launch Google's Chrome web browser and go to: http://192.168.255.254
   
   
5. Log into your ONS-C401i switch with the following default credentials:
   
   username = admin
   password = admin
   
   

Configuring Port VLAN Settings

The ONS-C401i's default switch management VLAN ID is 4093 and its default switch management port is 4. For ports 1, 2, and 3 the default VLAN ID is 1 and the default VLAN mode is Access (untagged).

However, there are situations where you may want to change the VLAN settings on your ONS-C401i (please read VLAN Modes Explained for more info).

For instance, you may want to have port 4 set up as VLAN mode Access with VLAN ID 4093, but have ports 1, 2, and 3 set up with different VLAN IDs. This configuration provides tighter security, because the switch's management interface cannot be accessed by disconnecting a device from ports 1, 2 or 3 and then connecting a computer in its place.

On the other hand, with this configuration you can’t communicate with connected devices and the switch management GUI from a single interface. To do this, both data and management would need to share the same VLAN ID.

Regardless of your particular application's VLAN requirements, the following examples will show you how to make the changes from the ONS-C401i management GUI.

IMPORTANT:

• If your ONS-C401i was previously part of a managed Connect system, reset it to default settings (hold down the reset button for 15 seconds) before configuring it as a standalone switch.
  
  
• Never change your management VLAN ID to one that does not exist on port 1, 2, 3, or 4 on your ONS-C401i.
  
  
• Always make sure that at least one port on your ONS-C401i (1, 2, 3, or 4) has been assigned the management VLAN ID (default is 4093).
  
  
• If you decide to add your ONS-C401i to a managed Connect system at a later date, make sure to reset it to default settings first.
  
  
  

Segregating Traffic by VLAN

To segregate the traffic on your ONS-C401i by VLAN, there are 3 basic steps:

- Create a new VLAN ID, if it doesn't already exist on the switch.
- Change the PVID (Port VLAN Identifier) to the desired VLAN ID.
- Change the VLAN from Excluded to Untagged for the specified port.

For example, let's say you wanted to configure ports 1 and 2 as VLAN mode Access with a VLAN ID of 100. In this setup, devices connected to ports 1 and 2 would be able to communicate with each other, but not with devices connected to ports 3 and 4. 

This configuration would require the following steps:

1. Create VLAN 100 by putting 100 in the VLAN ID / VLAN List field and clicking Apply.
   
   
   
   
   
2. Confirm that VLAN 100 is added to the VLAN Table.
   
   
   
   
   
3. Assign PVID 100 to both port 1 and port 2 and click Apply.
   
   
   
   
   
4. Confirm that ports 1 and 2 have been assigned VLAN ID 100.
   
   
   
   
   
5. Select VLAN ID 100 from the dropdown list and change the membership of ports 1 and 2 to Untagged. Then, scroll down and click Apply.
   
   
   
   
   
6. Make sure to remove the previous VLAN membership from both ports (VLAN 1 in this example) by selecting VLAN ID 1 from the dropdown box and setting ports 1 and 2 to Excluded.
   
   
   
   
   
7. Under Port-VLAN Mapping, confirm that the Administrative VLANs settings and the Operation VLANs settings for port 1 and port 2 are set to 100UP.
   
   
   NOTE: 100UP means that the port is configured to pass Untagged traffic with PVID 100.
   
   
8. Select Save from the dropdown box in the top-right corner.
   
   
   
   
   
9. Finally, click Save Configuration to FLASH to save your settings so that they will be retained after reboot of your ONS-C401i.
   
   

Accessing Management and Devices from a Single Interface

In order to be able to manage your ONS-C401i and see all of the devices connected to it, from a single interface (e.g. a PC), you need to set ports 1 to 4 as Access with the same VLAN ID.

For example, let's say you wanted ports 1 to 4 to all be configured as VLAN mode Access with a VLAN ID of 4093, and port 4 is already configured that way by default. In this setup, a PC connected to port 4 would be able to manage the ONS-C401i and connect to any devices plugged into ports 1, 2, or 3. 

This configuration would require the following steps:

1. Assign PVID 4093 to ports 1, 2, and 3 and click Apply.
   
   
   
   
   
2. Confirm that ports 1 through 4 are all configured with VLAN ID 4093.
   
   
   
   
   
3. Select VLAN ID 4093 from the dropdown list and change the membership of ports 1, 2, and 3 to Untagged. Then, scroll down and click Apply.
   
   
   
   
   
4. Make sure to remove the previous VLAN membership from ports 1, 2, and 3 (VLAN 1 in this example) by selecting VLAN ID 1 from the dropdown box and setting ports 1, 2, and 3 to Excluded.
   
   
   
   
   
5. Under Port-VLAN Mapping, confirm that the Administrative VLANs settings and the Operation VLANs settings for ports 1 through 4 are all set to 4093UP.
   
   
   NOTE: 4093UP means that the port is configured to pass Untagged traffic with PVID 4093.
   
   
   
6. Select Save from the dropdown box in the top-right corner.
   
   
   
   
   
7. Finally, click Save Configuration to FLASH to save your settings so that they will be retained after reboot of your ONS-C401i.
