Ethernet interfaces are similar to other types of interfaces in many ways. They have an IP address,
subnet mask, and gateway used to make routing decisions. They restrict the amount of bandwidth
and packet size. They can provide DHCP services, and they can verify the gateway is available.
Use Ethernet interfaces to control which physical ports exchange routing information with other
routers and how much information is exchanged through each one. The more routing information is
exchanged, the more efficient the routers should be. However, the routers also generate more
network traffic, and some routing protocols require a significant amount of configuration and
management.

LABEL DESCRIPTION
Edit Double-click an entry or select it and click Edit to open a screen where you can modify
the entry’s settings.
Remove To remove a virtual interface, select it and click Remove. The UAG confirms you want
to remove it before doing so.
Activate To turn on an interface, select it and click Activate.
Inactivate To turn off an interface, select it and click Inactivate.
Create Virtual
Interface
To open the screen where you can create a virtual Ethernet interface, select an Ethernet
interface and click Create Virtual Interface.
Object References Select an entry and click Object Reference to open a screen that shows which settings
use the entry. See Section 10.3.2 on page 123 for an example.
# This field is a sequential value, and it is not associated with any interface.
Status This icon is lit when the entry is active and dimmed when the entry is inactive.
Name This field displays the name of the interface.
IP Address This field displays the current IP address of the interface. If the IP address is 0.0.0.0 (in
the IPv4 network), the interface does not have an IP address yet.
In the IPv4 network, this screen also shows whether the IP address is a static IP
address (STATIC) or dynamically assigned (DHCP). IP addresses are always static in
virtual interfaces.
Mask This field displays the interface’s subnet mask in dot decimal notation.
Apply Click Apply to save your changes back to the UAG.
