LABEL DESCRIPTION
IP Addressing This field is only available when you select Enable in the DHCP field.
Values
Beginning IP This field specifies the first of the contiguous addresses in the IP address pool.
Address
Ending IP This field specifies the last of the contiguous addresses in the IP address pool.
Address
Auto reserve IP Select Enable to have the VMG record DHCP IP addresses with the MAC addresses the IP
for the same addresses are assigned to. The VMG assigns the same IP address to the same MAC address
host when the host requests an IP address again through DHCP.
DHCP Server This is the period of time DHCP-assigned addresses is used. DHCP automatically assigns IP
Lease Time addresses to clients when they log in. DHCP centralizes IP address management on central
computers that run the DHCP server program. DHCP leases addresses, for a period of time,
which means that past addresses are "recycled" and made available for future reassignment
to other systems.
This field is only available when you select Enable in the DHCP field.
Days/Hours/ Enter the lease time of the DHCP server.
Minutes
DNS Values This field is only available when you select Enable in the DHCP field.
DNS Select the type of service that you are registered for from your Dynamic DNS service
provider.
Select Dynamic if you have the Dynamic DNS service.
Select Static if you have the Static DNS service.
DNS Server 1 Enter the first and second DNS (Domain Name System) server IP address the VMG passes
to the DHCP clients.
DNS Server 2
LAN IPv6 Mode Setup
IPv6 State Select Enable to activate the IPv6 mode and configure IPv6 settings on the VMG.
LAN IPv6 Address Setup
Delegate prefix Select this option to automatically obtain an IPv6 network prefix from the service provider
from WAN or an uplink router.
Static Select this option to configure a fixed IPv6 address for the VMG's LAN IPv6 address.
ULA Pseudo- A unique local address (ULA) is a unique IPv6 address for use in private networks but not
Random Global routable in the global IPv6 Internet.
ID
Select this to have the VMG automatically generate a globally unique address for the LAN
IPv6 address. The address format is like fdxx:xxxx:xxxx:xxxx::/64.
ULA IPv6 Address Setup
IPv6 Address If you select static IPv6 address, enter the IPv6 address prefix that the VMG uses for the
LAN IPv6 address.
Prefix Length If you select static IPv6 address, enter the IPv6 prefix length that the VMG uses to generate
the LAN IPv6 address.
An IPv6 prefix length specifies how many most significant bits (starting from the left) in the
address compose the network address. This field displays the bit number of the IPv6 subnet
mask.
MLD Snooping Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the presence
of MLD hosts who wish to receive multicast packets and the IP addresses of multicast
groups the hosts want to join on its network. Select Enable MLD Snooping to activate MLD
Snooping on the VMG. This allows the VMG to check MLD packets passing through it and
learn the multicast group membership. It helps reduce multicast traffic.
