MAC address The Media Access Control address is a unique, 48-bit value
permanently saved in ROM at the factory to identify each Ethernet
network device. It is expressed as a sequence of 12 hexadecimal
digits printed on a label on the bottom of the SBG901. You need to
provide the HFC MAC address to the Internet Service provider. Also
called an Ethernet address, physical address, hardware address, or
NIC address.
NAT Network Address Translation is an Internet standard for a LAN to use
one set of IP addresses for internal traffic and a second set of IP
addresses for external traffic.
pass-through A pass-through client on the SBG901 LAN obtains its public IP
address from the Internet Service provider’s DHCP server.
port mirroring A feature that enables one port (source) on the SBG901 to be copied
to another port (destination) to be studied. The destination mirrors
the transmitted (from) or received (to) data on the source port to
enable the person managing the network to monitor activity.
port triggering A mechanism that allows incoming communication with specified
applications. Primarily used for gaming applications.
private IP An IP address assigned to a computer on the SBG901 LAN by the
DHCP server on the SBG901 for an address-specified lease time.
Private IP addresses are used by the SBG901 LAN only; they are
invisible to devices on the Internet. See also public IP address.
public IP address The IP address assigned to the SBG901 by the Internet Service
