NTERFACES

The NetScreen-5000 Series device allows you to combine two or more physical ports into a 
single virtual port. This virtual port is known as an aggregate interface. Only Secure Port 
Modules (SPMs) support this feature.

On a 5000-8G SPM, you can create up to four aggregate interfaces.

On a 5000-2G24FE SPM, you can create up to five aggregate interfaces.

The 5000-8G SPM supports only certain combinations of ports for aggregate interfaces. 
For example, a 5000-8G SPM residing in slot 2 only supports the following port 
combinations:

Ethernet2/1 and Ethernet2/2

Ethernet2/3 and Ethernet2/4

Ethernet2/5 and Ethernet2/6

Ethernet2/7 and Ethernet2/8

You must assign one of the following names to the aggregate interface: aggregate1, 
aggregate2, aggregate3, or aggregate4.

In the following example, you combine two Gigabit Ethernet mini-GBIC ports, each 
running at 1 Gbps, into an aggregate interface running at 2 Gbps. The aggregate interface 
consists of Ethernet ports 1 and 2 on a 5000-8G SPM (residing in slot 2).

To create the aggregate interface:

1.

(Optional) To see what physical ports are available on your NetScreen-5000 
Series device:

2.

To create an aggregate interface name: 

where string is a legal aggregate interface name (aggregate1, aggregate2, 
aggregate3, or aggregate4).

For example, to create the aggregate interface name aggregate1:

3.

To assign ports ethernet2/1 and ethernet2/2 to the aggregate1 interface name:

4.

interface:
