ARP Interval This field displays for arp Link Monitoring. Select the frequency of ARP requests sent to
confirm a that slave interface is up.
ARP IP Target This field displays for arp Link Monitoring. Set the IP address of the link to send ARP
queries.
Available This field displays Ethernet interfaces and VLAN interfaces that can become part of the
LAG interface. An interface is not available in the following situations:
• There is a virtual interface on top of it
• It is already used in a different LAG interface
Select one, and click the >> arrow to add it to the LAG interface. Each LAG interface
can only have one VLAN interface.
Slaves A slave is a physical Ethernet interface that is a member of a LAG. This field displays
the interfaces that are part of the LAG interface. Select one, and click the << arrow to
remove it from the LAG interface.
IP Address
Assignment
Get
Automatically
Select this if this interface is a DHCP client. In this case, the DHCP server configures
the IP address, subnet mask, and gateway automatically.
Use Fixed IP
Address
Select this if you want to specify the IP address, subnet mask, and gateway manually.
IP Address This field is enabled if you select Use Fixed IP Address.
Enter the IP address for this interface.
Subnet Mask This field is enabled if you select Use Fixed IP Address.
Enter the subnet mask of this interface in dot decimal notation. The subnet mask
indicates what part of the IP address is the same for all computers in the network.
Gateway This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The ZyWALL/USG sends packets to the gateway
when it does not know how to route the packet to its destination. The gateway should
be on the same network as the interface.
Metric Enter the priority of the gateway (if any) on this interface. The ZyWALL/USG decides
which gateway to use based on this priority. The lower the number, the higher the
priority. If two or more gateways have the same priority, the ZyWALL/USG uses the one
that was configured first.
Enable IGMP
Support
Select this to allow the ZyWALL/USG to act as an IGMP proxy for hosts connected on
the IGMP downstream interface.
IGMP Version: Select the IGMP version to be used on this ZyWALL/USG
interface.
IGMP Upstream Enable IGMP Upstream on the interface which connects to a router running IGMP that
is closer to the multicast server.
IGMP
Downstream
Enable IGMP Downstream on the interface which connects to the multicast hosts.
