3.1.5.2 DHCP Relay
A DHCP Relay can make broadcast messages to be sent over routers. An d a DHCP relay can
receive a DHCP broadcast request packet and forward it to a specified server.
Notice:
When a DHCP request packet comes, a DHCP relay receives it and then sends it to
all VLANs. But according to RFC 2131, when renewing, unicast DHCP request
packet will be sent to a DHCP server directly, not passing a DHCP relay, so it is
recommended to make sure that the DHCP client can ping the server after getting
an IP address.
DHCP Relay Configuration
DHCP Relay sends a unicast DHCP packet to the specified server(s). The maximum number of
specified servers is 5. You can enable or disable a DHCP relay function, and configure the

3.1.5.3 DHCP L2Relay
In some networks, DHCP servers rely on Relay Agent Information option append ed by Relay Agent s
for IP address and other parameter assi gnment policies. This works fine whe n end host s are directly
connected to Relay Agents. In some network configurations, one or more Layer 2 devices may
reside between DHCP client s 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.
DHCP snooping steps:
1. A DHCP client sends a DHCP request via 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 connect s to the h ost (circuit-ID
sub-option).
3-17
Page 37
DVS Series Managed Industrial Ethernet Switches User’s Manual
3. If the switch has configured an IP address, the IP address will be added into 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 unicast. And the switch checks whether the
remote-ID or circuit-ID in option-82 matches the value of the DHCP request, and makes sure it
sends from the certificated DHCP server. Then it removes the information 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, V2 and V3 are supported on the Delta switch, and it’s enabled by default.
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, password and IP address change traps.
3.2.1 SNMP V1/V2
SNMP version 1 (SNMPv1) 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.
SNMPv2 revises version 1 and includes improvements of performance, security, confidentiality, and
manager-to-manager communications. It adds a GetBulkRequest command; it sends iterative
GetNextRequests for retrieving large amounts of management data in a single request.
3.2.1.1 Community Configuration
There are two default communities preconfigured for SNMPv1 and SNMPv2:
public: All IP addresses can be accessed with a rea d-only permission.
private: All IP addresses can be accessed with a read/write permission.
Community Configuration
Description Factory Default

associated with a single client IP address.
For example, the client’s IP address is 192.168.1.X, subnet mask is
255.255.255.0. If the client’s IP address is between 192.168.1.0 and
192.168.1.255, they are allowed to be accessed. If the client’s IP
address is 192.168.1.15 and subnet mask is 255.255.255.255, only
this client allows to be accessed.
0.0.0.0
Access Mode
Specify the access mode:
ReadOnly: Only allow the client to read information.
ReadWrite: Only allow the client to read information and modify
configuration.

3.3 Network Redundancy
In some network environments, users need to set up redundant loo ps in the network to provide a
backup path for disconnection or 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 b usy 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 communications 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 Save
Configuration page after you have applied the configuration
changes. (Save ConfigSave Configuration) If you don’t
save the configuration, then the configuration will be cleared
after the switch is rebooted.
3.3.1 STP
Spanning Tree Protocol (STP) provides a tree topology to help 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 information and it 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 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 backward compatible with standard STP.
Delta switch supports different protocol s to support communi cation redunda ncy. 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 loop in a network.
3-37
Page 57
DVS Series Managed Industrial Ethernet Switches User’s Manual
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 each bridge can
communicate each other without loop.
If the link failure is detected
between Bridge B and C, STP/RSTP will start to reconfigure the
network.
3-38
Page 58
Chapter 3 Featured Functions
Then the traffic between Bridge B and C will flow through Bridge A.
But STP/RSTP can’t support more VLANs in your network topology. If there are 2 VLANs between 2
bridges, one path will be blocked when STP/RSTP is enabled. So IEEE defined an extension to
RSTP to further develop the usefulness of VLANs.
3-39
Page 59
DVS Series Managed Industrial Ethernet Switches User’s Manual
Multiple Span ning 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

3.3.1.4 CST Port Status
The type of port role of the interface:
Root Port: It’s a concept of STP. Every non-root switch has one root port. The lowest cost of the
path to the root switch will be the root port.
Master Port: It’s a concept of MSTP. It must meet two conditions: one is root port in CIST; the
other one is an edge port. The edge port is the port which connects two regions.
Designated Port: The port responsible for forwarding data to the downstream network segment
or device.
Alternate Port: The standby port for the root port or master port. If a root port or master port is
blocked, the alternate port becomes the new root port or master port.
Backup Port: The backup port of designated ports. When a designated port is blocked, the
backup port becomes a new designated port and starts to forward data without delay. When a
loop occurs while two ports of the same MSTP device are interconnected, the device will block
either of the two ports, and the backup port is that port to be blocked.

3.4 Virtual LANs
Virtual LAN (VLAN) is a logically group network. VLANs electronically separate interfaces on the
3-55
Page 75
DVS Series Managed Industrial Ethernet Switches User’s Manual
same switch into different broadcast domains so that broadcast packets are not sent to all the
interfaces on a single switch. VLAN allows switch manager to isolate network traffic so that only
members of the VLAN could receive traffic from the same VLAN members. VLAN also allow a user
to access the network from a different place or switch. So VLAN provide security and flexibility.
For example: Configure department A, B, C to VLAN 1, 2, 3. User only can access the resource
which belongs 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 don’t need to
stay in a fixed place to access the resource which belongs to their department.
IMPORTANT:
Make sure that you save the configuration in the Save
Configuration page after you have applied the configuration
changes. (Save ConfigSave Configuration) If you don’t
save the configuration, then the configuration will be cleared
after the switch is rebooted.
3.4.1 VLAN Configuration
VLAN Configuration is used to define VLAN groups and the VLAN information will be stored in the
VLAN membership table. Delta switch supports up to 256 VLANs. VLAN 1 is the default VLAN, and
all interfaces are untagged members by default setting.
Note:
By default, all interfaces are untagged members of VLAN 1, the default VLAN.
However, interfaces that you make members of link aggregation groups (that is,
physical interfaces that function as trunk members) lose their membership of the
default VLAN.

3.4.4 Port PVID Configuration
VID (VLAN ID) is the tag of VLAN. It defines the interface which can receive the packets of the
VLAN; PVID (Port VLAN ID) which defines the untagged port can forward which VLAN’s packets.
For example: If port 1 belongs to VLAN 1, 2, 3, and its PVID is 1, port 1 can receive the packets from
VLAN 1, 2, 3, but it only can 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 VLAN 1. If there is no other values specified, the default VLAN PVID is used for untagged or
priority-tagged frames.

3.5 Multicast Filtering
Multicast IP traffic is traffic that is assigne d to a host group. Host groups are identified by class D IP
addresses, which range from 224.0.0.0 to 239.255.255.255. A multicast IP packet only sends by one
3-60
Page 80
Chapter 3 Featured Functions
host to multiple hosts. 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 request 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 bandwidt h. If
there is a network with the multicast filtering, then it reduces the load of resources (ex. a se rver) a nd
makes the network bandwidth efficient.
Network without Multicast Filtering:
(All hosts receive the multicast traffic.)
3-61
Page 81
DVS Series Managed Industrial Ethernet Switches User’s Manual
Network with Multicast Filtering:
(Only the host which belongs to the group can receive the traffic.)
IGMP Snooping manages multicast traffic by making use of switches, routers, and hosts that
support IGMP. Enabling IGMP Snooping allows the ports to detect IGMP queries, report pa ckets,
and manage multicast traffic through the switch. IGMP has three fundamental types of messages,
as shown below:
Message Description
Query
A message sent from the querier (an IGMP router or a switch) which
asks for a response from each host that belongs to the multicast
group.
Report
A message sent by a host to the querier to indicate th at the host
wants to be or is a member of a given group indicated in the report
message.
Leave Group
A message sent by a host to the querier to indicate th at the host has
quit as a member of a specific multicast group.
IMPORTANT:
Make sure that you save the configuration in the Save
Configuration page after you have applied the configuration
changes. (Save ConfigSave Configuration) If you don’t
save the configuration, then the configuration will be cleared
after the switch is rebooted.

3.6 Traffic Prioritization
Traffic prioritization provides you to make sure the time-sensitive and system-critical data can be
transferred with minimal delay. It uses four queues that are present in UI from high priority to low
priority.
Delta switch supports DSCP trust mode, 802.1p trust mode, queue scheduling (Support Weighted
Round Robin and Strict-Priority) and 4 level priority queues. The traffic prioritization depends on 2
methods:
IEEE 802.1P: a layer 2 marking scheme.
Differentiated Services (DiffServ): a layer 3 marking scheme.
IMPORTANT:
Make sure that you save the configuration in the Save
Configuration page after you have applied the configuration
changes. (Save ConfigSave Configuration) If you don’t
save the configuration, then the configuration will be cleared
after the switch is rebooted.
3.6.1 QoS
Quality of Service (QoS) provides a traffic prioritization for you to alleviate congestion problem and
ensure high-priority traffic is delivered first. If the bandwidth of the network is limited, you can use
QoS to schedule the priority of a different service packet flow.

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 n etwork time out.
Delta switch can measure the incoming pa cket rate of 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 threshol d of the
traffic flow.

3.9 Port Trunking
Port Trunking can help you to aggregate more links to form one link group. Delta DVS switch’s LAG
function supports 3 trunk groups, and you can assign 8 ports to one group. But there is a limit of 3
gigabit ports or 7 10/100Mbps port s for each lag ID. Link Aggregation (LA) increase s the capacity
and availability of the communication channel between devices (both switches and end stations)
using existing Fast Ethernet and Gigabit Ethernet technology. LA also provides load bal ancing
where the processing and communication activity is distributed across sev eral links in a trunk.
If there are 4 ports in a trunk group, and one port fails, then the other seven ports will provide
backup and share the traffic automatically. LA also can be used to combine 4 ports between Delta
DVS switches. If all ports on these two switches are configured as 100BaseTX and full duplex, then
the potential bandwidth of the connection can be 400Mbps.

3.10 Access Control List
Access control lists (ACLs) can make sure that only authorized devices have access to specific
resources when any unauthorized devices which are blocked attempt to access network resources.
ACLs provide security for the network, traffic flow control, and determine which types of traf fic can
be forwarded or blocked.
Delta switch supports ACLs based on the MAC addresses of the source and destination devices
(MAC ACLs).
3-75
Page 95
DVS Series Managed Industrial Ethernet Switches User’s Manual
The steps of configuring an ACL:
1. Create a MAC-based ACL name.
2. Create a rule and assign it to an ACL.
3. Assign an ACL to an interface.
3.10.1 MAC ACL
A MAC ACL consists of a set of rules that are matched sequentially to compare the packet. With a
MAC ACL, you can specify the MAC add ress of the so urce device, destination device, or both.
When a packet matchs the criteria with a rule, and the specified rule action (permit or deny) is
applied, then any additional rules will not be checked whether the packet is match or not.
MAC ACL

3.10.2 MAC Rules
After creating an ACL name, you can configure the action, match, destination MAC, source MAC
and VLAN in this page. It can determine whether the packet is forwarded normally or discarded.
Note:
You need to create an implicit deny all rule at the end of an ACL rule table to make
sure that a packet is dropped if an ACL is applied to the packet and none of the
explicit rules match.
