1.2. Ports and Connectors
This section is an overview of the hardware's external design and construction.
Figure 1.2. Rear view of the Clavister SG10 Series.
The SG10 features an RS232 console port on the far left. To the right are 6 Fast Ethernet interface
ports which can operate at 10Mb or 100Mb speeds. These ports are referred to by the administrator
using logical interface names. The first 4 ports are marked LAN 1 to LAN 4. The two ports at the
right are marked as AUX, and WAN. These ports fullfill the following functions:
WAN This port should be connected to the external wide area network (eg. the internet). It is
100Base-T or 10Base-T capable. The default interface name is wan.
AUX This port is also 100Base-T or 10Base-T capable. The default interface name is aux.
LAN 1-4 These ports are general purpose interfaces that connect to the main processor via a
switch chip which is common to all seven ports. All are designed to be connected to
internal networks. All 4 ports share a single default logical interface names which is
called lan. In other words any rule in the IP rule-set that uses lan as the source or
destination interface will apply to traffic on any of the physical ports LAN 1-4.
Ethernet Connection Limitations
With the SG10 Series there is a limit to how many devices can be connected via the ethernet ports.
This number is determined by the type of SG10 license purchased and the size of CorePlus ARP
table that the license allows.
Changing default interface names
The default logical interface names assigned to physical ports can be changed later by the SG10
Series appliance administrator. In the case of lan, changing this name will change the shared name
for physical ports LAN 1-4.
Important
Traffic that enters a SG10 Series device by one of the 4 general purpose interfaces
LAN1 to LAN4 and then leaves by another of those same 4 interfaces destined for the
same IP subnet, will not be subject to the CorePlus IP rule-set. This is because that
traffic will pass through the device's internal switch logic and it will be sent directly to
the destination interface by the switch.
