CONFIGURING JUMBO FRAMESThe 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.
CONFIGURING AGGREGATE INTERFACESThe 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:
