The 5000-8G2 and 5000-2XGE SPMs support jumbo frames that are up to 9,830 
bytes. To set jumbo frames, use the set environment max-frame-size=9830 
CLI command. You must reboot the system before this feature can take effect.

NTERFACES

The NetScreen-5000 Series system 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 5000-8G2 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 and 5000-8G2 SPM support 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 system:

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:
