General Description
Supporting 16-port SS-SMII, 2-port MII and
various advanced features, the IP1718 LF fits both
the office switch and the ETTH( Ethernet to the
Home) application. The IP1718 LF embeds
internal SSRAM for the use of the packet buffer
and the MAC address table. Besides the
traditional switch functions, the IP1718 LF
provides the easy-to-design solution, fitting the
requirement of most switch application.
The IP1718 LF also supports some features which
can simplify the customer’s design from the
viewpoint of the system. The embedded regulator
controller can reduce the component number on
the system board. The web management can be
easily accomplished by adding an external CPU
with protocol stack. All the I/O pins can operate at
3.3V or 1.8V, providing more design flexibility for
power supply distribution.
The IP1718 LF embeds 1.5Mb internal packet
buffer and stores up to 4K MAC address entries,
making it suitable for the generic switch
application. In addition, the IP1718 LF supports a
wide range of data rate for both egress and
ingress, which is useful in the ETTH(Ethernet to
the Home) application. The higher layer data
packet such as BPDU, IGMP, OSPF can be
forwarded to either the 17th or 18th (CPU) port. The
flexible trunk configuration allows the user to scale
the switch interconnection bandwidth. When the
port mirroring function is enabled, the data traffic
on the source port will be forwarded to a specified
destination port, making the switch administration
easier. Supporting up to 18 port based VLAN
groups, the IP1718 LF can be configured to fit
various traffic partitions. The CoS function is
accomplished by configuring the priority of the
physical port, the 802.1Q VLAN tag and IP
DSCP(Differentiated Service Code Point). In order
to fit the application of some special environment,
the address learning and the MAC address table
aging can be disabled.
