Chapter 10 Interface

Each physical port is assigned to one Ethernet interface. In port grouping, the Ethernet interfaces are called representative interfaces. If you assign more than one physical port to a representative interface, you create a port group. Port groups have the following characteristics:

•There is a layer-2 Ethernet switch between physical ports in the port group. This provides wire-speed throughput but no security.

•It can increase the bandwidth between the port group and other interfaces.

In the example below, you might combine physical ports 3 and 4 into port group ge3.

Figure 127 Port Grouping Example: Network

In this case, click Network > Interface > Port Grouping, and set up the screen like this.

Figure 128 Port Grouping Example: Screen

There are no ports assigned to ge4. If you do not assign any physical ports to a representative interface, you cannot use this interface to create other interfaces or create IPSec VPN tunnels. The Ethernet interface is still displayed in the screen, however, and the existing configuration remains.

10.3.2 Port Grouping Screen

You can maintain the relationship between physical ports, port groups, and Ethernet interfaces in the Port Grouping screen. To access this screen, click Network > Interface > Port Grouping.
