Defining System Communication Interfaces for Layer 2 Firewall Engines
Defining System Communication Interfaces for Layer 2
Firewall Engines
Each Layer 2 Firewall engine needs at least one interface for communicating with other SMC
components. More than one system communication interface can be added to provide a primary
and a backup interface for Management Server communications.
Defining Physical Interfaces
 To define a Physical Interface
1. Switch to the Interfaces tab.
2. Right-click and select New Physical Interface. The Physical Interface Properties dialog
opens.
3. Select the Interface ID.
4. Select Normal Interface as the Type.
5. Click OK.
The Physical Interface is added to the interface list. Add the necessary number of interfaces in
the same way.
Defining VLAN Interfaces
VLANs divide a single physical network link into several virtual links. You can add up to 4094
VLANS per interface.
 To define a VLAN Interface
1. Right-click a Physical Interface and select New→VLAN Interface. The VLAN Interface
Properties dialog opens.
2. Enter the VLAN ID (1-4094).
3. Click OK.
The specified VLAN ID is added to the Physical Interface.
Repeat the steps above to add further VLANs to the interface.
The VLAN Interface is now ready to be used as a network interface. The VLAN Interface is
identified as
Interface-ID.VLAN-ID, for example 2.100 for Interface ID 2 and VLAN ID 100.
What’s Next?
 If you want to add VLANs to the Physical Interface, continue by Defining VLAN Interfaces.
 Otherwise, continue by Defining IP Addresses (page 46).
Note – The VLAN ID must be the same VLAN ID used in the switch at the other end of the
VLAN trunk.
