1.2. Interfaces and Ports
This section is an overview of the E7 product's external design.
Figure 1.2. Clavister E7 Connection Ports
The E7 features the following connection ports on the front panel:
• On the left there is a set of RJ45 Gigabit Ethernet interfaces which are numbered 1 to 8. All 8
interfaces are connected together by a common switch fabric and share the single logical
cOS Core interface name GESW. This means that any security policy in the cOS Core rule sets
that refers to the interface GESW will apply to traffic on any of the 8 physical interfaces.
The GESW interfaces allow the configuration of Port Based VLANs through cOS Core so that
the 8 interfaces can be divided up into different VLANs. This feature is described further in
Appendix C, Port Based VLAN Setup.
• Next, are 3 x RJ45 Gigabit Ethernet interfaces. These have the logical cOS Core names of G1,
G2 and G3. The names are marked on each interface. These interfaces function
independently of each other and are not connected by a switch fabric.
• There are two versions of the E7 appliance. The first generation version (revision A) provides
console connection through an RS-232 RJ45 connector port. The second generation version
(revision B) uses a micro-USB port. All images in this manual show only the micro-USB port
version.
The console port is used for direct access to the cOS Core Boot Menu and the cOS Core
Command Line Interface (CLI). Access can be password protected.
All E7 Ethernet interfaces are capable of link speed auto-negotiation and can operate using
10Base-T, 100Base-Tx, or 1000Base-T.
Figure 1.3. The E7 Ethernet Interface Ports
All the E7 Ethernet interfaces support Automatic MDI-X and do not require a crossover cable for
direct connection from another computer.
The full connection capabilities of all E7 Ethernet interfaces are listed in Appendix A, E7
Specifications.

For the E7 only, cOS Core allows the administrator to configure of any of the GESW interfaces so
