Configure the Name of the Bridge Group Interface and Select the Bridge Group Members

In this procedure you give the bridge group interface (BVI) a name and select the interfaces to add to the bridge group:

Procedure

1

In the left pane, click Security Devices.

2

Click the Devices tab to locate the device or the Templates tab to locate the model device.
3

Click the FTD tab and select the device for which you want to create a bridge group.

4

Do one of the following:

  • Select the BVI bridge group and click Edit in the Actions pane.

  • Click the plus button and select Bridge Group Interface.


 

You can create and configure a single bridge group. If you already have a bridge group defined, you should edit that group instead of trying to create a new one. If you need to create a new bridge group, you must first delete the existing bridge group.
5

Configure the following:

  • Logical Name-You must give the bridge group a name. It can be up to 48 characters. Alphabetic characters must be lower case. For example, inside or outside. Without a name, the rest of the interface configuration is ignored.


 

If you change the name, the change is automatically reflected everywhere you used the old name, including security zones, syslog server objects, and DHCP server definitions. However, you cannot remove the name until you first remove all configurations that use the name, because you typically cannot use an unnamed interface for any policy or setting.

  • (Optional) Description-The description can be up to 200 characters on a single line, without carriage returns.
6

Click the Bridge Group Member tab. A bridge group can have up to 64 interfaces or subinterfaces to a single bridge group.

  • Check an interface to add it to the bridge group.

  • Uncheck an interface you want to remove from the bridge group.
7

Click Save.

The BVI now has a name and member interfaces. Continue with the following tasks to configure the bridge group interface. You are not performing these tasks for the member interfaces themselves:
