Configuration
Available This field displays Ethernet interfaces and VLAN interfaces that can become part of the
bridge 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 bridge interface
Select one, and click the >> arrow to add it to the bridge interface. Each bridge interface
can only have one VLAN interface.
Member This field displays the interfaces that are part of the bridge interface. Select one, and click
the
<< arrow to remove it from the bridge 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.
DHCP Option 60 DHCP Option 60 is used by the Zyxel Device for identification to the DHCP server using the
VCI (Vendor Class Identifier) on the DHCP server. The Zyxel Device adds it in the initial DHCP
discovery message that a DHCP client broadcasts in search of an IP address. The DHCP
server can assign different IP addresses or options to clients with the specific VCI or reject
the request from clients without the specific VCI.
Type a string using up to 64 of these characters [a-zA-Z0-9!\"#$%&\'()*+,-./
:;<=>?@\[\\\]^_`{|}~] to identify this Zyxel Device to the DHCP server. For example, Zyxel-
TW.
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.
IPv6 Address
Assignment These IP address fields configure an IPv6 IP address on the interface itself.
