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 Zyxel Device 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 Zyxel Device 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 Zyxel Device uses the one that was configured
first.
Enable IGMP Support Select this to allow the Zyxel Device to act as an IGMP proxy for hosts connected on the
IGMP downstream 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.
DHCP Setting
DHCP Select what type of DHCP service the Zyxel Device provides to the network. Choices are:
None - the Zyxel Device does not provide any DHCP services. There is already a DHCP
server on the network.
DHCP Relay - the Zyxel Device routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP Server - the Zyxel Device assigns IP addresses and provides subnet mask, gateway,
and DNS server information to the network. The Zyxel Device is the DHCP server for the
network.
These fields appear if the Zyxel Device is a DHCP Relay .
Relay Server 1 Enter the IP address of a DHCP server for the network.
Relay Server 2 This field is optional. Enter the IP address of another DHCP server for the network.
