NTERFACES
Each NetScreen-5XT provides ethernet interfaces for access and connectivity. In addition,
there are logical (non-physical) interfaces that perform special Layer-2 or management
functions.
The configurable interfaces available on a NetScreen-5XT are as follows:
Interface Type
Description
Ethernet interfaces
These interfaces are denoted by a physical port on the module although each
interface is bound to a security zone by default.
Trusted1
-
Trusted4
Bound to the
Trust
security zone by default. Connect
this interface using a twisted pair cable with RJ-45 connectors.
Untrusted
Bound to the
Untrust
security zone by default. Connect this
interface using a twisted pair cable with RJ-45 connectors.
Layer-2 interfaces
vlan1
specifies a logical interface used for management and for VPN traffic
termination while the NetScreen-5XT is in Transparent mode.
Loopback interfaces
loopback
emulates a physical interface on the NetScreen-5XT. A loopback
interface is always in the up state as long as the device on which it resides is
up.
Tunnel interfaces
untrust-tun
specifies a logical tunnel interface. This interface is for VPN
traffic.
