Juniper Networks 5000 manual Configuring Jumbo Frames, Configuring Aggregate Interfaces

Chapter 3 Configuring the Device

CONFIGURING JUMBO FRAMES

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=9830CLI command. You must reboot the system before this feature can take effect.

CONFIGURING AGGREGATE INTERFACES

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:

get interface

2.To create an aggregate interface name:

set interface string zone zonename

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

For example, to create the aggregate interface name aggregate1: set interface aggregate1 zone zonename

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

set interface ethernet2/1 aggregate aggregate1 set interface ethernet2/2 aggregate aggregate1
