3.3.3. VLAN Chapter 3. Fundamentals Modified Ethernet wan. Some interface settings are accessible only through a related set of CLI commands. These are particularly useful if D-Link hardware has been replaced and Ethernet card settings are to be changed, or if configuring the interfaces when running NetDefendOS on non-D-Link hardware. For example, to display Ethernet port information use the command: gw-world:/> show EthernetDevice This command shows all Ethernet interfaces defined. This list includes those interfaces deleted but before an activate has been done. Deletions will be indicated with a "-" symbol before their name. If a deleted interface in the list is to be restored, this can be done with the undelete command: gw-world:/> undelete EthernetDevice The following command can also be used to list interface information: gw-world:/> show Ethernet Interface The set command can be used to control an Ethernet interface. For example, to enable an interface lan we can use the command: gw-world:/> set EthernetDevice lan -enable To set the driver on an Ethernet interface card the command is: gw-world:/> set EthernetDevice lan EthernetDriver= PCIBus= PCISlot= PCIPort= For example, if the driver name is IXP4NPEEthernetDriver for the bus, slot, port combination 0, 0, 2 on the wan interface, the set command would be: gw-world:/> set EthernetDevice lan EthernetDriver=IXP4NPEEthernetDriver PCIBus=0 PCISlot=0 PCIPort=2 For a complete list of all CLI options see the CLI Reference Guide. 3.3.3. VLAN Overview Virtual LAN (VLAN) support in NetDefendOS allows the definition of one or more Virtual LAN interfaces which are associated with a particular physical interface. These are then considered to be logical interfaces by NetDefendOS and can be treated like any other interfaces in NetDefendOS rule sets and routing tables. VLANs are useful in several different scenarios. A typical application is to allow one Ethernet interface to appear as many separate interfaces. This means that the number of physical Ethernet ports on a NetDefend Firewall need not limit how many totally separated external networks can be connected. Another typical usage of VLANs is to group together clients in an organisation so that the traffic belonging to different groups is kept completely separate in different VLANs. Traffic can then only flow between the different VLANs under the control of NetDefendOS and is filtered using the security policies described by the NetDefendOS rule sets. 97
