1 Precautions

Power supply sockets with too heavy load or broken cables and plugs

may cause electric shock or fire. Users should check the power supply
wires and cables regularly. If there is any breakage, please replace the
cable at once.

Do not open the case of the device, especially during device power-on.
The device should be installed at position with good ventilation and

without high temperature or direct sunshine, so as to avoid faults of the
device and its corresponding components due to overheat.

Do not put this device close to a damp or watery place. Do not spill

any fluid on this device.

Keep proper space for heat dissipation, to avoid any damage to the

device caused by overheating. The holes on the shell are designed for
heat dissipation, to ensure that the device works normally. Do not
cover the heat dissipation holes.

Keep the power plug clean and dry, if abnormal phenomenon occurs,

such as smoke, abnormal sound, abnormal smell, switch off the power.

7.6 VLAN Setting

In large networks, routers are used to isolate broadcast traffic for each subnet into separate
domains. This switch provides a similar service at Layer 2 by using VLANs to organize
any group of network nodes into separate broadcast domains. VLANs confine broadcast
traffic to the originating group, and can eliminate broadcast storms in large networks. This
also provides a more secure and cleaner network environment.

The system supports VLAN based on port and VLAN based on tag. You can change the
VLAN mode in the VLAN Mode page.

DG-FS1510HPE User Manual

7.8 QoS Configuration

All switches or routers that access the Internet, rely on class information to provide the same
forwarding treatment to packets in the same class. Class information can be assigned by end
hosts, or switches or routers along the path. Priority can then be assigned based on a general
policy, or a detailed examination of the packet. However, note that detailed examination of
packets should take place close to the network edge so that core switches and routers are not
overloaded.

Switches and routers along the path can use class information to prioritize the resources
allocated to different traffic classes. The manner in which an individual device handles traffic
is called per-hop behavior. All devices along a path should be configured in a consistent
manner to construct a consistent end-to-end Quality of Service (QoS) solution.

Choose QoS Setting, and the sub-menus of QoS Setting are shown as below.

802.1p (bit [15:13]) in the VLAN Tag. Packets in which values of

802.1p (bit [15:13]) are 000-011 map to lower priority. Packets in which
values of 802.1p (bit [15:13]) are 100-111 map to higher priority.

Based on IP / DS:

For IPv4 packets, the priority is determined according to the value of
TOS [5:0] in the header. Packets in which values of TOS [5:0] are
101110, 001010, 010010, 011010 and 11x000 map to higher priority.

7.10.3 Loopback Detection:

Choose Spanning Tree > Loopback Detection to configure loopback detection on an
interface. When loopback detection is enabled and a port receives it‘s own BPDU, the
detection agent drops the loopback BPDU and places the interface in discarding mode. This
loopback state can be released automatically.

7.11 Trunking

This section describes how to configure static and dynamic trunks.

You can create multiple links between devices that work as one virtual aggregate link. A port
trunk offers a dramatic increase in bandwidth for network segments where bottlenecks exist,
as well as providing a fault tolerant link between two devices.

The switch supports both static trunking and dynamic Link Aggregation Control Protocol
(LACP). Static trunks have to be manually configured at both ends of the link. On the other
hand, LACP configured ports can automatically negotiate a trunked link with
LACP-configured ports on another device.

Choose Trunking, and the Link Aggregation Settings sub-menu is shown as below.

Choose Trunking > Link Aggregation Settings, and the following page appears.

9 Glossary

Auto-negotiation: Auto-negotiation is an Ethernet procedure by which two connected

devices choose common transmission parameters, such as speed, duplex mode and flow
control. In this process, the connected devices first share their capabilities as for these
parameters and then choose the highest performance transmission mode they both support.

Backpressure: The build-up of data behind an I/O switch if the buffers are full and

incapable of receiving any more data; the transmitting device halts the sending of data
packets until the buffers have been emptied and are once more capable of storing
information.

Flow-control: Flow control is the process of managing the pacing of data transmission

between two nodes to prevent a fast sender from outrunning a slow receiver. It provides a
mechanism for the receiver to control the transmission speed, so that the receiving node is not
overwhelmed with data from transmitting node.

Address Learning: Address learning is a service that characterizes a learning bridge, in

which the source MAC address of each received packet is stored so that future packets
destined for that address can be forwarded only to the bridge interface on which that address
is located.

TCP: The Transmission Control Protocol (TCP) is one of the core protocols of the Internet

Protocol Suite. TCP is one of the two original components of the suite, complementing the
Internet Protocol (IP), and therefore the entire suite is commonly referred to as TCP/IP. TCP
provides reliable, ordered delivery of a stream of bytes from a program on one computer to
another program on another computer.

UDP: User Datagram Protocol. UDP provides a datagram mode for packet-switched

communications. It uses IP as the underlying transport mechanism to provide access to
IP-like services. UDP packets are delivered just like IP packets – connection-less datagrams
that may be discarded before reaching their targets. UDP is useful when TCP would be too
complex, too slow, or just unnecessary.

FTP: File Transfer Protocol (FTP) is a standard network protocol used to copy a file from

one host to another over a TCP-based network, such as the Internet. FTP is built on
client-server architecture and utilizes separate control and data connections between the client
and server.

Http: The Hypertext Transfer Protocol (HTTP) is a networking protocol for distributed,

collaborative, hypermedia information systems.

TELNET: Telnet defines a remote communication facility for interfacing to a terminal

device over TCP/IP.

ToS: Type of Service level, which processes the precedence part of the IP packet ToS (3

bits) as an index to the eight QoS Class values.

Link-Aggregation: Link aggregation is a term which describes using multiple network

cables/ports in parallel to increase the link speed beyond the limits of any one single cable or
port, and to increase the redundancy for higher availability.

COS: Class of Service is supported by prioritizing packets based on the required level of

service, and then placing them in the appropriate output queue. Data is transmitted from the
queues using weighted round-robin service to enforce priority service and prevent blockage
of lower-level queues. Priority may be set according to the port default, the packet‘s priority
bit
(in the VLAN tag), TCP/UDP port number, IP Precedence bit, or DSCP priority bit.

SNMP: Simple Network Management Protocol. The application protocol in the Internet

suite of protocols which offers network management services.

QOS: Quality of Service. QoS refers to the capability of a network to provide better service

to selected traffic flows using features such as data prioritization, queuing, congestion
avoidance and traffic shaping. These features effectively provide preferential treatment to
specific flows either by raising the priority of one flow or limiting the priority of another
flow.

DHCP: Dynamic Host Control Protocol. Provides a framework for passing configuration

information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol
(BOOTP), adding the capability of automatic
allocation of reusable network addresses and additional configuration options.

DHCP OPTION 82: A relay option for sending information about the requesting client

(or an intermediate relay agent) in the DHCP request packets forwarded by the switch and in
reply packets sent back from the DHCP server. This
information can be used by DHCP servers to assign fixed IP addresses, or set other services
or policies for clients.
