# Managing NCOS

Network classes of services (NCOS) are similar to FCOS, except that every network bit controls one of the twelve network options (see NCOS Fields Description). You can have a maximum of 64 NCOS on the system.

You can

- List NCOS

- Add an NCOS

- Edit an NCOS

- Delete an NCOS

- See a list of NCOS Fields Description

## Listing NCOS

To display a list of all NCOS in the system

- In the navigation tree, click Class of Service and then click Network COS.

## Add an NCOS

1. In the navigation tree, click Class of Service and then click Network COS. The Network COS list is displayed.

2. Click Add. The Add NCOS form is displayed.

3. Do one of the following:

1. - Copy an existing NCOS by selecting one from the list and clicking the Copy from button. The parameters of that NCOS will be copied into your new NCOS, which you can then edit as required. The Next Available NCOS number is automatically applied.
     OR

   - Chose to manually select all limits for the new NCOS

4. In the Number field, enter a number (1-64) for this NCOS, or click Next Available to automatically assign the next number.

5. In the Name field, enter a name (up to 15 alphanumeric characters) for this NCOS.

6. Select the check box beside each network bit that you want to enable for the NCOS. (Clear a check box to disable the selection.) For a list of network bits, see NCOS Fields Description.

7. To save the NCOS and return to the Network COS list, click Save

## Edit an NCOS

Best practices dictate that you always keep your default NCOS intact. If you need to modify an NCOS, we suggest that you copy the default NCOS into a new NCOS (see "Add an NCOS" above) and modify it there. After you save the new NCOS, you need to assign it to the appropriate mailboxes. This way, if you have problems/conflicts with the new COS, you can always restore the default until you have finished troubleshooting.

## Delete an NCOS

Deleting an NCOS that is in use by mailboxes will cause all of those mailboxes to be assigned the default (1) NCOS. A warning message is displayed to allow you to cancel the operation. If you are deleting the default NCOS, the mailboxes assigned to it will be assigned to the next available NCOS. You cannot delete the last remaining NCOS in the system; therefore, you cannot select all NCOS for deletion.

To delete one or multiple NCOS

1. In the Network COS list, select one or multiple NCOS, and then click Delete. The system will prompt you to confirm the deletion.

2. To confirm the deletion, click Yes for a single deletion or Yes to all for a range.
   OR
   To reject the deletion, click No.
