Click Reset to change the port groups to their current configuration (last-saved values).
7.3 Ethernet Summary Screen
This screen lists every Ethernet interface and virtual interface created on top of Ethernet interfaces.
If you enabled IPv6 in the Configuration > System > IPv6 screen, you can also configure
Ethernet interfaces used for your IPv6 networks on this screen. To access this screen, click
Configuration > Network > Interface > Ethernet.
Unlike other types of interfaces, you cannot create new Ethernet interfaces nor can you delete any
of them. If an Ethernet interface does not have any physical ports assigned to it, the Ethernet
interface is effectively removed from the ZyWALL, but you can still configure it.
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. The ZyWALL supports two routing protocols, RIP and OSPF. See Chapter 10 on page
199 for background information about these routing protocols.
