3.5 Connecting to the Ethernet Interface
I. Ethernet interface
H3C SecPath F100-A firewall provides four fixed 10/100 Mbps autosensing LAN
interfaces, and three fixed 10/100 Mbps autosensing WAN interfaces for connection to
switches or routers.
Note:
The four LAN interfaces on H3C SecPath F100-A firewall can work at Layer 2 and in
Hub mode. You can configure the four LAN interfaces to work at Layer 3 by executing
the
insulate
command in system view. At this time, the interfaces LAN0, LAN1, LAN2
and LAN3 on the firewall correspond to E0/0, E0/1, E0/2 and E0/3 interfaces in the
command line respectively; by executing the
undo insulate
command in system view,
you can configure the four LAN interfaces to work in Hub mode. At this time, the
interfaces LAN0, LAN1, LAN2 and LAN3 on the firewall correspond to interface E0/0 in
the command line; WAN0, WAN1 and WAN2 interfaces correspond to E1/0, E1/1 and
E1/2 interfaces in the command line respectively.
II. Ethernet cable
The H3C SecPath F100-A firewall uses the category-5 twisted pair cable to connect its
Ethernet interfaces. See Figure 3-4.

Note:
When preparing network cables, it is recommended to use shielded cables for the sake
of electromagnetic compatibility.
