Using the ONS-C2401p as a Standalone Switch

This article explains how to configure the ONS-C2401p so that it can be managed without OneView™, as a standalone switch.

Although primarily designed to be connected to Optigo's aggregation switch and managed from OneView™, the ONS-C2401p can also be managed as a standalone switch with its built-in management interface.

Accessing the ONS-C2401p Management Interface

1. With your ONS-C2401p powered up, but connected to no other equipment, reset it to defaults by holding down the reset button for 15 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 24 on the ONS-C2401p.
   
   
4. Launch Google's Chrome web browser and go to: http://192.168.255.254
   
   
5. Log into your ONS-C2401p switch with the following default credentials:
   
   username = admin
   password = password
   
   

Changing Password and Privilege Settings

The password should be changed after the initial login to avoid easily guessable passwords. There is a different password for every user account, these accounts can be added or removed in the User Management section.

The password can be edited here along with the privilege of each account. 

A user account can have admin privileges, allowing them to make configuration changes, or a user account, for viewing only.

Changing IP Address Settings

The IPv4 settings can be changed to allow for a static IP address or for the device to receive an IP address from a DHCP server. Navigate to IPv4 under System.

Set MAC Locking

The MAC address of a device can be used to ensure that only a specified number of devices can connect to the network using a port. We set the max number of MACs that the port will allow before it begins denying access to devices. 

1. Firstly, enable port security on a port in the Port Security tab. In this example we have chosen to lock port 13. 
2.  Then set the ‘max MAC address’ to the number of devices connecting via the specified port. In this case we want to ensure only one device can use this port.
3. When the desired changes have been made. Click Apply.

Configuring Port VLAN Settings

The ONS-C2401p's default switch management VLAN ID is 4093 and its default switch management port is 24. For ports 1 through 23 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-C2401p (please read VLAN Modes Explained for more info).

For instance, you may want to have port 24 set up as VLAN mode Access with VLAN ID 4093, but have ports 1 to 23 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 - 23 and then connecting a computer in its place.

On the other hand, with this configuration you cannot 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-C2401p management GUI.

IMPORTANT:

• If your ONS-C2401p 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 any of the Ethernet ports, or you will be unable to manage your ONS-C2401p.
  
  
• Always make sure that at least one port on your ONS-C2401p has been assigned the management VLAN ID (default is 4093).
  
  
• If you decide to add your ONS-C2401p 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-C2401p 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 - 24. 

This configuration would require the following steps:

1. Go to the 802.1Q page and click the Add button on the right.
2. Enter 100 in the VID field and then click on the Untagged Port field.
   
   
3. Select radio buttons 1, and 2 in the untagged row and then click Confirm.
4. Confirm that 1-2 is displayed in the Untagged Port field and then click the checkmark on the far right (i.e. Apply).
5. Confirm that 100 is now listed in the VID column and that only untagged ports 1 through 2 have that VLAN ID.
6. Click on the edit button in the VID 1 row.
7. Remove ports 1 and 2 from VLAN ID 1 by selecting the radio buttons in the none row, then click Confirm. 
8. Confirm that the Untagged Port value in the VID 1 row changes from 1-24 to 3-24.
9. Enter 100 in the PVID field at the top of the PVID page, check the check boxes for ports 1 and 2, and then scroll down to the bottom to click Apply.
10. Confirm that ports 1 through 2 have been assigned PVID 100.               
    

Accessing Management and Devices from a Single Interface

In order to be able to manage your ONS-C2401p and see all of the devices connected to it, from a single interface (e.g. a PC), you need to set ports 1 to 24 as Access with the same VLAN ID.

For example, let's say you wanted ports 1 to 24 to all be configured as VLAN mode Access with a VLAN ID of 4093, and port 24 is already configured that way by default. In this setup, a PC connected to port 24 would be able to manage the ONS-C2401p and connect to any devices plugged into ports 1 through 24. 

This configuration would require the following steps:

1. Click on the edit button in the VID 4093 row.
2. Click on the Untagged Port field in the VID 4093 row.
3. Select radio buttons 1 through 24 in the untagged row and then click Confirm.
4. Confirm that 1-24 is displayed in the Untagged Port field and then click the checkmark on the far right (i.e. Apply).
5. Click on the edit button in the VID 1 row.
6. Remove ports 1 through 24 from VLAN ID 1 by selecting the radio buttons in the none row. Then click Confirm followed by the checkmark on the far right (i.e. Apply).
7. Confirm that the Untagged Port value in the VID 1 row changes from 1-28 to 25-28.
8. Enter 4093 in the PVID field at the top of the PVID page, check the check boxes for ports 1 through 24, and then scroll down to the bottom to click Apply.
9. Confirm that ports 1 through 24 have been assigned PVID 4093.
