OUTING
Overlapped IP interfaces define multiple logical interfaces for a single
physical port. You can specify how UDP Helper forwards packets from
overlapped IP interfaces using the
To configure UDP Helper to support overlapped IP interfaces:
1 From the top level of the Administration Console, enter:
ip udpHelper interface
2 Enter one of these interface configuration options:
first — The system uses the first overlapped IP interface as the source
network for forwarded packets.
even — The system hashes the client's MAC address to determine the
source network for forwarded packets. This procedure evenly
distributes the interface used among those on the network.
sequential — The system assigns each overlapped IP interface, in
turn, as the source network for forwarded packets.
The system implements your selection immediately. You can view the UDP
Helper configuration after you configure the forwarding address.
You can control whether the system forwards or discards IP packets
addressed to other hosts. When you enable IP routing, the system acts as
a normal IP router, routing IP packets from one subnetwork to another
when required. When you disable IP routing, the system discards any IP
packets that are not addressed directly to one of its defined IP interfaces.
The default IP routing setting is disabled on the system.
To enable or disable IP routing:
1 From the top level of the Administration Console, enter:
ip routing
2 Enter the IP routing state (
