Configuring Aggregate Interfaces
The NetScreen-5000 Series system allows you to combine two or more physical
ports on an SPM into a single virtual port. This virtual port is known as an aggregate
interface. Only Secure Port Modules (SPMs) support this feature. Table 8 describes
the aggregate interfaces supported on the various SPMs.

5000-8G
5000-8G2 and

5000-2G24FE
You assign the aggregate interface a name of the format aggregate1 through
aggregate n , where n is the total of the maximum number of aggregate interfaces
supported by all of the SPMs in the chassis.
In the following example, you combine two SFP 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
2. To create an aggregate interface name:
3. To assign ports ethernet2/1 and ethernet2/2 to the aggregate1 interface name:

Supported Aggregations
Only the following port combinations:
1 and 2
3 and 4
5 and 6
7 and 8
Any combination of ports 1 through 4, or
any combination of ports 5 through 8. You
cannot aggregate ports 1 through 4 with
ports 5 through 8.
Any combination of up to 8 FE ports per
aggregate interface. You can also aggregate
the two SFP ports together. You cannot
aggregate FE ports and SFP ports together.
