DESCRIPTION
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-

Use Fixed IP
Select this if you want to specify the IP address, subnet mask, and gateway manually.
Address
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
Enable IGMP Downstream on the interface which connects to the multicast hosts.
Downstream
IPv6 Address
These IP address fields configure an IPv6 IP address on the interface itself.
Assignment

generates itself for the interface.

static IP address for this interface. This field is optional.
The prefix length indicates what the left-most part of the IP address is the same for all
computers in the network, that is, the network address.
Gateway
Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal
notation.
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.
