3.3.2. Ethernet Interfaces
i. Make the interface a member of all routing tables. This option is enabled by default and
means that traffic arriving on the interface will be routed according to the main routing
table. Routes for the interface IP will be inserted into all routing tables.
ii. The alternative to the above is to insert the route for this interface into only a specific
routing table. The specified routing table will be used for all route lookups unless
overridden by a routing rule.
• Automatic Route Creation
Routes can be automatically added for the interface. This addition can be of the following types:
i. Add a route for this interface for the given network. This is enabled by default.
ii. Add a default route for this interface using the given default gateway. This is enabled by
default.
• MTU
This determines the maximum size of packets in bytes that can be sent on this interface. By
default, the interface uses the maximum size supported.
• High Availability
There are two options which are specific to high availability clusters:
1. A private IP address can be specified for this interface.
2. An additional option is to disable the sending of HA cluster heartbeats from this interface.
• Quality Of Service
The option exists to copy the IP DSCP precedence to the VLAN priority field for any VLAN
packets. This is disabled by default.
Changing the IP Address of an Ethernet Interface
To change the IP address on an interface, we can use one of two methods:
• Change the IP address directly on the interface. For example, if we want to change the IP
address of the lan interface to 10.1.1.2, we could use the CLI command:
gw-world:/> set Interface Ethernet lan IP=10.1.1.2
As explained next, this way of changing the IP address is not recommended.
• Instead, the ip_lan object in the NetDefendOS Address Book should be assigned the new
address since it is this object that is used by many other NetDefendOS objects such as IP rules.
The CLI command to do this would be:
gw-world:/> set Address IP4Address ip_lan Address=10.1.1.2
This same operation could also be done through the Web Interface.
A summary of CLI commands that can be used with Ethernet interfaces can be found in
Section 3.3.2.1, "Useful CLI Commands for Ethernet Interfaces".
