USB driver. You can find the driver in the CD package.
Example 1:
There is a DHCP server in your environment, and the Delta switch can get an IP address from the DHCP
server. I f y o u d on’t want to check the IP address from the DHCP serv er, then you can use the USB console
cable to login to the Delta switch. Using the “show network” command can display the IP address
information of the Delta switch.
Example 2:
If you want to change the network configuration protocol from DHCP mode to static mode, using CLI
commands to change the protocol and setting a static IP address and a subnet mask.

When a DHCP request packet comes, the DHCP relay receives it and then sends it to all VLANs. But
according to RFC 2131, when a unicast DH CP request packet renews, it will be sent to a DHCP
server directly without passing a DHCP relay, so it is recommended to make sure that the DHCP client
can ping the server after getting an IP address.

3.1.5.3 DHCP L2 Relay
In some networks, DHCP s erv ers rely o n the Relay Age nt Inf or mat ion o pti on ap pen ded by Relay Agent s for the
IP address and other parameter assignment policies. This works fine when end hosts are directly connected to
Relay Agents. In some network configurati ons, one or more Layer 2 devices may reside between DHCP clients
and a Relay agent. In these network scenarios, it is difficult to use the Relay Agent Information option for an IP
address and other parameter assignment policies effectively. So there is a requirement for the device that is
closest to the end hosts to append a Relay Agent Information option in DHCP messages. These devices are
typically known as Layer 2 Relay Agents. The operating theor y is shown in the figure below.

Enable: Enable the relay agent information option.
DHCP snooping steps:
1. A DHCP client sends a DHCP reque st via the broadcast.
2. When a switch (relay agent) receives the DHCP request, it will add DHCP option-82 to the packet. DHCP
option-82 includes the MAC address of the host which sends a DHCP request (remote-ID sub-option) and
the interface ID on the switch which connects to the host (circuit-ID sub-option).
3. If the switch has configured an IP address, the IP address will be added to the DHCP packet.
4. If a DHCP server supports option-82, after the DHCP server receives the DHCP request, it will allocate the
IP address numbers according to the remote-ID sub-option or circuit ID sub-option.
5. A DHCP server responds to the switch via the unicast. And the switch chec ks whether the remote-ID or the
circuit-ID in option-82 matches the value of the DHCP request, and makes sure it sends from the
certificated DHCP serv er. Then it removes the informati on of option-82, and sends back to the interface on
the switch which sends the DHCP request.

3.2 SNMP Manager
Simple Network Management Protocol (SNMP) is an application protocol used for exchanging management
information between network devices. SNMP is a member of the TCP/IP protocol suite. SNMP v1, v2c and v3
are supported on the Delta switch, and it is enabled by default.
The Delta switch supports standard public MIBs for standard functionality and private MIBs that provide
additional functionality. You can use SNMP to enable or disable authentication traps, cold-start and warm-start
functionality traps, link up and link down traps, Spanning Tree Protocol (STP) traps, SFP traps, and password
and IP address change traps.

then the configuration will be cleared after the switch is rebooted.
3.2.1 SNMP v1/v2c
SNMP version 1 (SNMP v1) is the initial implementation of the SNMP protocol. The authentication of clients is
performed by a "community string", like a type of password, which is transmitted in clear text.
SNMP v2c revises version 1 and includes improvements of performance, security, confidentiality, and
manager-to-manager communications. It adds a GetBul kR eq uest co mmand; it sends iter at i v e

If network engineers need to get information f rom an SNMP agent (n etw ork devi ce), t hey us ually u se the SNMP
software to poll information and get a response from an agent. But the SNMP Trap is the unsolicited trap which
sends from the agent to the NMS (Network Management System).The operating theory is shown in the figure

An SNMP agent sends SNMP trap messages to the trap community (trap receiver). It monitors the switch for
particular events or conditions, and generates trap messages based on these events or conditions.

3.3 Network Redundancy
In some network environments, users need to set up redundant loops in the network to provide a backup path
for disconnection or a network device breakdown. But if there are many network devices in the network, then
each host needs to spend more time and cross many network devices to associate with each other. And
sometimes the disconnection happens in a busy network, so the network must recover in a short time. Setting
up redundancy on your network helps protect critical links against failure, protects against network loops, and
keeps network downtime at a minimum. For example, if the Delta switch is used as a key communication
component of a production line, several minutes of downtime may cause a big loss in production and revenue.
IMPORTANT:
Make sure that you save the configuration in the Sav e Co nfigur atio n
page after you have applied the configuration changes. (Save
Config
then the configuration will be cleared after the switch is rebooted.
3.3.1 STP
Spannin g Tree Protocol (STP) provides a tree topology that helps reduce link failure in a network, find one path
between end devices and protect loops in the network. Bridge Protocol Data Unit (BPDU) includes the
calculation of informat ion and i t is used to negotiate between switches and establish STP. STP is a bridge
based system and it defines 5 kinds of port statuses: blocking, listening, learning, forwarding and disabling. If
the status of the blocking changes to forwarding, STP needs to spend more than 30 seconds.
Rapid Spanning Tree Protocol (RSTP) was defined by IEEE in 2001. RSTP provides faster tree convergence
after a topology changes. Sometimes it only needs to spend a few hundred milliseconds. And RSTP can be
backward compatible with standard STP.
The Delta switch supports different protocols to support communication redundancy. When configuring a
redundant ring, all switches on the same ring must be configured to use the same redundant protocol.
STP/RSTP can let you establish a redundant ring and protect the l oop in a network, as shown in the figure
below.
Save Configuration) If you do not save the configuration,
If STP/RSTP is enabled, it will detect duplicate paths, calculate the cost of each path and block the lowest cost
path (ex. the path between A and C) from forwarding traffic. So bridges can communicate with each other
without loops, as shown in the figure below.
3-40
Page 62
Chapter 3 Featured Functions
If the link failure is detected between bridge B and bridge C, STP/RSTP will start to reconfigur e the network, as
shown in the figure below.
Then the traffic between bridge B and bridge C will flow through bridge A , as shown in the figure below.
3-41
Page 63
DVS Managed Industrial Rack Mount Ethernet Switch User Manual
But STP/RSTP can not support more VLANs in y our network topology. If there are 2 VLANs betw een 2 br i dge s,
one path is blocked when STP/RSTP is enabled. So IEEE defined an extensi on to RSTP to further develop the
usefulness of VLANs.
Multiple Spanning Tree Protocol (MSTP) is an extension protocol of RSTP. It can provide an independent
spanning tree for different VLANs. MSTP builds a separate Multiple Spanning Tree (MST) for each instance.
And MST Region may include multiple MSTP instances. The operating theory is shown in the figure below.

3.3.2 Redundancy
To keep the industrial network run non-stop, the Ethernet redundancy network is an essential feature in the
industrial ethernet network. The D elt a ma naged switch provides three topologies: ONE RING, ONE CHAIN and
ONE COUPLING.
These redundancy topology operating theories look like STP, but when a connection failure was caused in the
network, it can quickly recover the connection and work normally.
3.3.2.1 ONE RING Configuration
The ONE RING topology consists of nodes having two ports participating in ONE RING. There are two types of
nodes, which namely master nodes and slave nodes. There can be only one master and up to 250 slave
nodes.
The ports and LAGs which are the members of ONE RING should disable the STP mode and the

3.4 Virtual LANs
Virtual LAN (VLAN) is a logical group network. VLANs electronically separate interfaces on the same switch
into different broadcast do mains so that broadcast packets are not sent to all the interfaces on a single switch.
VLAN allows the switch man a ger to i sola te network traffic so that only m emb er s o f the VLAN can receive traf fi c
from the same VLAN members . VLAN also al low s a user to acce ss the netw ork fro m a different place or switc h.
So VLAN provide security and flexibility.
For example: Configure dep ar tment A, B, C to VLAN 1, 2, 3. U sers can only access the r esource w hich bel ongs
to their department, so the resource in their department can be protected. And they can access the resource in
a different floor, even though in a different place. So they do not need to stay in a fixed place to access the
resource which belongs to their department.

3.4.5 Port PVID Configuration
VID (VLAN ID) is the tag of VLAN. It defines the interface which can receive the packets of the VLAN; PVID

For example: If por t 1 belongs to VLAN 1, 2, 3, a nd its PVID i s 1, port 1 can receive the packets from V LAN 1, 2,
3, but it can only forward the packets to VLAN 1.
The default port VLAN ID (PVID) is assigned to 1 on all interfaces, because they are assigned to default VLA N

3.5 Multicast Filtering
Multicast IP traffic is traffic that is assigned to a host group. Host groups are identified by class D IP addresses,
which range from 224.0.0 .0 to 239.2 55.255.2 55. A multicast IP packet is only sent by one host to mul tiple h ost s.
Only those hosts that belong to a specific multicast group will receive the multicast. The Internet Group
Management Protocol (IGMP) snooping enables the switch to forward multicast traffic intelligently to only the
interface that requests the multicast traffic. So the network resource is not wasted too much.
If there is a network without the multicast filtering, and a host needs to send data to many hosts, then it needs
to produce several copies in the network. It wastes too much network bandwidth. If there is a network with the
multicast filtering, then it reduces the load of resources (ex. a server) and makes the network bandwidth
efficient. The figure s below sh ow the dif f erence between the network without M ulticast F ilter ing and th e netw ork

3.6.1 QoS
Quality of Service (QoS) provides a traffic prioritization for you to alleviate the congestion problem, and ensure
that high-priority traffic is delivered first. If the ban dwidth of the network i s li mit ed, y ou can u se Q oS to schedule
the priority of a different service packet flow.
3.6.1.1 QoS Setting
QoS Setting
Global: Specify the trust mode settings for all interfaces and aggregation groups. Then, make a selection
from the Global Trust Mode drop-down list.
Make a selection from the Global Trust Mode drop-down list that affects all
interfaces or aggregation group s:
trust dot1p: All interfaces or aggregation groups are configured for the 802.1p
marking to classify traffic.
trust ip-dscp: All interfaces and aggregation groups are configured for the IP
trust dot1p
Make a selection from the Global Schedule Scheme drop-down list that affects all
interfaces:
sp: SP (Strict-Priority) classifies the queue from the high priority to the low
priority. If the higher priority of the queue is empty , the lower priority data of the
queue starts to be sent.
wrr: WRR (Weighted Round Robin) schedules the queue by turns, so each
queue has a service time. Each queue can be allocated a weight value or
Interface: Specify the trust mode settings for an individual interface and aggregation groups. Select
an interface or aggregation groups from the Interface drop-down list, and then make a selection from the

3.6.1.2 CoS Queue Mapping
This page allows you to configure the CoS value for the physical queue mapping table. The field specifies a
priority value between 0 and 7, and the Delta sw itch prov ides 4 physical queues which can be used by Quality
of Service (QoS) for differentiate network traffic.
Interface Selection
Specify one of the following selections:
Select from 0/1 through 0/9: Specify an individual interface.
Select from po1 through po3: Specify a link aggregation group.
Select All: Specify all interfaces and link aggregation groups.
CoS Queue Mapping
Select a queue to which you want to map the priority. The traffic class is the selected queue (Low, Normal,
Medium, or High) for an interface.
The default queues of the CoS are mapped in the way described below.
3.6.1.3 DSCP Queue Mapping
This page allows you to configure the DSCP value to the physical queue mapping table. The field specifies a
priority value betw een 0 an d 6 3, and the Delta switch provides 4 physical queues which ca n be u sed by Quality
of Service (QoS) for differentiate network traffic. Users can configure the mapping table to follow the upper
layer 3 switch or the routers’ DSCP setting.

3.8.1 Storm Control
A traffic storm occurs when incoming packets flood the LAN, which causes th e decrea si ng of the netw or k
performance. The storm control can prevent flooding packets from affecting the network performance. The
Delta switch allows you to conf igure both storm control for each interface and rate limiting of each interface for
incoming and outgoing traffic.
3.8.1.1 Storm Control Setting
A broadcast storm occurs when a large number of broadcast messages are transmitted from a single interface
across a network at the same time. Forwarding these messages can overload too much network resources or
cause the network timeout.
The Delta switch can measure the incoming packet rate of the broadcast, multicast, and unknown unicast
packets for each interface and discards packets when the rate exceeds the defined value. You can enable
storm control for each interface by a different packet type and define the threshold of the traffic flow.
Save Configuration) If you do not save the configuration,
