2.3 Network Ports
The EP-808DG-S provides eight 10Base-T/100Bate-TX/1000BASE-T (RJ
-45 connector) ports.
2.4 Console Port
The console port interface conforms to the RS-232 electrical specification
and locates on the front panel. This interface supports asynchronous data of eight
data bits, one stop bit, and no parity bit. The unit only operates at 38400bps rates
with RS-232 cable in system configure.
2.5 L2 Switching Functions
2.5.1 Switching
EP-808DG-S supports 10M/100M or Gigabit Ethernet interfaces (1000Base-T).
All 10M/100M ports support half/full-duplex mode and 1000M ports support full
-duplex mode. When packet enters a port, its destination MAC address is checked
up entries in an address database to see which port can lead to its destination.
When matched destination port is found, the frame is queued and waiting for
forwarding to that port(s). The EP-808DG-S provides output packet buffering so
that data can be switched among multiple ports. If the destination address is found
to be the local port, the frame is dropped or filtered. If the destination address is
not found in the address database, the frame is flooded to all ports except the
incoming port.
A broadcast frame or multicast frame is always flooded to all ports except the
incoming port.
The source MAC address of each frame is recorded into the address
database along with the port number of the port where it enters the switch. The
information is then used for later decision for frame forwarding.
The address database can hold up to 16K addresses. Each entry in the
address hash table is associated with a particular 48-bit IEEE MAC address. The
table contains all of the information required to process, filter or switch packets to
known (i.e., previously learned) addresses.
An entry in the address database will be discarded if it has not been refreshed
for a period time called aging time. This is to ensure correct operation when a
node is moved to another port and to keep the table clean. Aging timer has a
default value and is configurable through UI.

2.5.2 Forwarding Modes
EP-808DG-S only supports Store and Forward operation.The store and forward
mode of operation is the same as a conventional bridge where received packets are
buffered entirety prior to forwarding. This ensures that only whole packets with
a good CRC are passed to the destination.
2.5.3 Flow Control
EP-808DG-S is provided with the facility to minimize packet loss due to sustained
excess load exceeding the ability of the switchs receiving buffers to store frames.
In full-duplex operation, this is done by the protocol defined in the 802.3x standard.
EP-808DG-S will respond to received flow control packets and generate its own
depending upon memory availability when flow control function being set. The
factory default of this feature is disabled.
2.5.4 Port Mirroring
Any port can be mirrored by port eighth such that all the traffic received and/or
transmitted by that port will be copied to the monitoring port. Only single port and
single direction can be monitored at the same time.
2.5.5 VLAN
EP-808DG-S has Virtual LAN (VLAN) capabilities to restrict the flow of multicast and broadcast traffic to only the end stations requiring them. Any traffic
passing between VLANs must do so through an external router.
2.5.6 Priority
EP-808DG-S supports the following priority features:
1. Priority associated with individual packets:
When 802.1Q tagging is used, the packet carries 3 priority bits in its VLAN ID.
The 802.1Q tag priority will always be used on an 802.1Q link. The hardware is
programmable as to which priority bits are treated as high priority. For this product,
high priority treatment is given to packets with a priority value of 4-7.
2. Four Queues
Output packet will be queued to one of four queues depending on the setting
of the VLAN tag value.
2.5.7 Link Aggregation
Link Aggregation is to connect multiple links/ports to the same partner in order
to achieve higher network throughput. The following groups of 2 to 4 ports can
be trunked in EP-808DG-S:
1,2 3,4 5,6 7,8
1 to 3 3 to 5 5 to 7 6 to 8
1 to 4 5 to 8
Any port within a group above can be regarded as one trunk if they are configured as a logical link.
Automatic load balancing is performed by the switching core that will
reconfigure the traffic distribution across the multiple links in the event of a link
becoming inactive. This is based upon a hashing algorithm of the source address of
each packet. This ensures that conversations between units will remain on the
same link to guarantee frame ordering.
The link aggregation can be enabled by UI.

2.5.8 Management
The EP-808DG-S can be configured through the console port (out-of-band
management).
2.5.9 Console Interface
The console interface can be accessed from the DB-9 connector on the
rear panel and only operate on 38400bps. EP-808DG-S provides menu driven
command interface. The terminal connected to EP-808DG-S should be a VT-100
compatible terminal in order to display menu properly. The console commands
can be used to configure the functions of the switch and show the network statistics.User will see a login screen after EP-808DG-S is powered on. A valid password must be input in order to log into the system.
2.5.10 Security
The EP-808DG-S supports basic security to prevent illegal access from UI. It is
built by password request at log in screen. Without correct password, user cannot
access switch setting and monitor switch status.
