THE NETSCREEN-ISG 2000 INTERFACES
The NetScreen-ISG 2000 provides physical ports, each of which can serve as a physical
interface. In addition, you can configure Ethernet ports to serve as virtual (logical)
interfaces.

Configurable Interfaces

The interfaces available on the NetScreen-ISG 2000 are as follows:

The Ethernet Interfaces

The ethernet interfaces are located on the interface modules (see “Interface Modules” on
page 6). The interface names are as follows:
Interface Type Description
Ethernet interfaces ethernetn1/n2 specifies a physical Ethernet interface, denoted by an
interface module in a slot (n1) and a physical port (n2) on the module.
ethernetn1/n2.n3 specifies a logical interface, denoted by an interface
module in a slot (n1), a physical port (n2) on the module, and a logical
interface number ( .n3). You create logical interfaces using the set interface
command.
Layer-2 interfaces vlan1 specifies the interface used for VPNs while the NetScreen device is in
Transparent mode.
Tunnel interfaces tunnel.n specifies a tunnel interface. Use this interface for VPN traffic.
Function interfaces mgt specifies an interface bound to the MGT zone. The default IP address of
this interface is 192.168.1.1.
