DHCPv6 Client > Physical Settings
This page configures the physical settings of a DHCPv6 Client interface.
Bridge interfaces
When disabled, the logical interface covers only a single physical interface. When enabled, the user may
choose to bridge two or more interfaces together. A bridge switches packets between the ports in the bridge
based on L2 (ethernet) addresses, ignoring the L3 (IP) addresses. The IP addresses are used for routing only
for packets between logical interfaces.
Interface
Select the physical interface (e.g. ETH1, ETH2 or SFP) that this logical interface covers. If ‘Bridge interfaces’
is selected, then you may select multiple.
Enable STP
Only for bridged interfaces using Spanning Tree Protocol. This is designed to prevent loops in L2 networks.
Enable this protocol if there is any chance of a loop. If connecting to narrow band links (such as Aprisa SR+)
it is often advisable to disable the STP protocol.
Enable IGMP snooping
Only for bridged interfaces. When enabled, the bridge can determine what ports to deliver multicast packets
to by listening to the IGMP (Internet Group Management Protocol) packets. When disabled, multicast packets
are sent to all ports in the same way as broadcast packets. This helps to reduce traffic going to links not
involved in the multicast conversation.
