1Introduction
1.1 Introduction to Industrial Managed Switch
Atop’s EH (Ethernet Hub) 9711 series are product lines of powerful industrial managed switch which are referred to as Open
Systems Interconnection (OSI) Layer 2 bridging devices. Unlike an “unmanaged” switch, which is normally found in homes
or in Small Office/Home Office (SOHO) environments and runs in “auto-negotiation” mode, each port on a “managed switch”
can be configured for its link bandwidth, priority, security, and duplex settings. The managed switches can be managed by
Simple Network Management Protocol (SNMP) software, web browsers, Telnet, or serial console. Since every single port can
be configured to specific settings, network administrators can better control the network and maximize network functionality.
Atop’s managed switch is also an industrial switch and not a commercial switch. A commercial switch simply works in a
comfortable office environment. However, an industrial switch is designed to perform in harsh industrial environments, i.e.,
extreme temperature, high humidity, dusty air, potential high impact, or the presence of potentially high static charges. Atop’s
managed switch works fine even in these environments.
Atop’s managed switch is designed to provide faster, secure, and more stable network. Advantages that make it a powerful
switch are that it supports security such as IP Source Guard, DHCP Snooping, ARP Inspection as well as Access Control List
(ACL) and network redundancy protocols/technologies such as Ethernet Ring Protection Switching (ERPS), Rapid Spanning
Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP). These protocols provide better network reliability and
decrease recovery time.
Atop’s managed switch supports a wide range of IEEE standard protocols. This switch is excellent for keeping systems running
smoothly, reliable for preventing system damage or losses, and friendly to all levels of users. The goal of this innovative
product is to bring users an enhanced network management experience.
Note:
Throughout the manual, the symbol * indicates that more detailed information of the subject will be provided at the end of this
book or as a footnote.

2Configuring with a Web Browser
There are three ways to configure Atop’s Industrial Managed Ethernet Switch: Web browser, Telnet console, and Serial
console. How to access the industrial managed switch through web browser is explained in Chapter 2 through Chapter 5. There
are only a few differences among these three methods.The web browser and the telnet console methods allow users to access
the switch over the Internet or the Ethernet LAN, while the serial console method requires a serial cable connection between
the console and the switch.Users are recommended to configure the switch via a web browser because of its user-friendly
interface.
Next, we will proceed to use a web browser to introduce the managed switch’s functions. It is recommended to use Microsoft
Edge 103, Firefox 44, Chrome 48 or later versions. Below is a list of default factory settings. This information will be used
during the login process. Make sure that the computer accessing the switch are in the same subnet. That is the computer has an
IP address and the subnet mask same as the switch. Please pay attention when inputting the username and password, as they
are case sensitive.
IP Address: 10.0.50.1
Subnet Mask: 255.255.0.0
Default Gateway: 0.0.0.0
User Name: admin
Password: default
Before users can access the configuration, they have to log in. This can simply be done in the following steps.
1. Launch a web browser.
2. Type in the switch IP address (e.g. http://10.0.50.1), as shown in Figure 2.1).
Note: When the user name and the password are left empty, the login prompt will not show.
Figure 2.1 IP Address for Web-based Setting
3. The user can enter a Username and a Password to access the managed switch. Then, clicking on the Sign in
button.

4. If the user entered wrong passwords, users can try to re-enter the new username and password again until it is
correct. Or users can simply click the Cancel button to forfeit the process.
5. If the login process was success, the user will be presented with the Port State Overview webpage which shows
the front panel of the managed switch as shown in Figure 2.3.

2.1.1 Information
This subsection describes how users can assign system’s details to the Atop’s switch. There are three fields in this System
Information Configuration webpage: System Contact, System Name, and System Location. By entering this unique and
relevant system information, it will help identifying one specific switch among all the others in the network. However, the
switch must support a SNMP protocol. Figure 2.5 shows the System Information Configuration Webpage to an EH9711
managed switch model. Please click the “Save” button to update the information on the switch. Clicking on the Reset button
will undo any changes made locally and revert to previously save values. Table 2.1 summarizes the device information setting
descriptions and corresponding default factory settings.

2.1.2 IP
In this subsection, the user may modify network settings on Internet Protocol (IP) for the managed switch. This subsection is
divided into three parts: IP Configuration, IP Interfaces, and IP Routes, as shown in
Table 2.7. First, the IP Configuration part is related to how the managed switch will be operated as Host. The IP Interfaces
part is related to IP Address configuration and DHCP configuration for both IPv4 and IPv6. Finally, the IP Routes part
contains the routing table that provides information about the network destination, gateway, next hop, and distance.
Figure 2.6 Webpage to Configure System’s IP Information.
The first part as shown in Figure 2.6 allows the user to set the operating mode of the managed switch. The user can enter up
to four DNS Servers. A DNS (domain name system) proxy allows clients to set up device as a DNS proxy server. A DNS
proxy improves domain lookup performance by caching previous lookups. A typical DNS proxy processes DNS queries by
issuing a new DNS resolution query to each name server that it has detected until the hostname is resolved. Table 2.2
provides detailed description of each option in this part which is also called basic setting.

Mode
Configure the IP stack to act as a Host, where IP traffic between interfaces will not be routed.
DNS Server
This setting controls the DNS name resolution done by the switch.
There are four servers available for configuration, and the index of the server presents the preference
(less index has higher priority) in doing DNS name resolution.
The following modes are supported:
- No DNS server: No DNS server will be used.
- Configured IPv4: Explicitly provide the valid IPv4 unicast address of the DNS Server in dotted
decimal notation. Make sure the configured DNS server could be reachable (e.g. via PING) for
activating DNS service.
- Configured IPv6: Explicitly provide the valid IPv6 unicast (except local link) address of the DNS
Server. Make sure the configured DNS server could be reachable (e.g. via PING6) for activating DNS
service.
- From any DHCPv4 interfaces: The first DNS server offered from a DHCPv4 lease to a DHCPv4-
enabled interface will be used.
- From this DHCPv4 interface: Specify from which DHCPv4-enabled interface a provided DNS
server should be preferred.
- From any DHCPv6 interfaces: The first DNS server offered from a DHCPv6 lease to a DHCPv6-
enabled interface will be used.
- From this DHCPv6 interface: Specify from which DHCPv6-enabled interface a provided DNS
server should be preferred.
DNS Proxy
When DNS proxy is enabled, system will relay DNS requests to the currently configured DNS server,
and reply as a DNS resolver to the client devices on the network.
Only IPv4 DNS proxy is now supported
The second part of IP Setting section is the IP Interface part as shown in Figure 2.8. The user can choose to enable DHCP
(Dynamic Host Configuration Protocol) for DHCPv4 and/or DHCPv6 by checking the box behind it. That is the IP address
and related information can be automatically obtained from a DHCP server in the local network thus reducing the work for an
administrator. By disabling this function (DHCP’s box is unchecked), the user has an option to setup the static IP address and
related fields manually. If DHCP is disabled, the user should enter the IP addresses and Max Length (subnet mask) under IPv4
and/or IPv6 columns. Table 2.3 provides detailed description of each option in this part of IP Interfaces.

Description
IF
The VLAN associated with the IP interface. Only ports in this VLAN will be able to
access the IP interface. This field is only available for input when creating a new
interface
DHCPv4 Enabled
Enable the DHCPv4 client by checking this box. If this option is enabled, the system
will configure the IPv4 address and mask of the interface using the DHCPv4 protocol.
DHCPv4 Client ID Type
This specified which of the three types below, i.e. IfMac, ASCII or HEX, shall be used
for the Client Identifier. See RFC-2132 section 9.14.
DHCPv4 Client ID ifMac
The interface name of DHCP client identifier. When DHCPv4 client is enabled and the
client identifier type is 'ifmac', the configured interface's hardware MAC address will
be used in the DHCP option 61 field.
DHCPv4 Client ID ASCII
The ASCII string of DHCP client identifier. When DHCPv4 client is enabled and the
client identifier type is 'ascii', the ASCII string will be used in the DHCP option 61
field.
DHCPv4 Client ID HEX
The hexadecimal string of DHCP client identifier. When DHCPv4 client is enabled and
the client identifier type 'hex', the hexadecimal value will be used in the DHCP option
61 field.
DHCPv4 Hostname
The hostname of DHCP client. If DHCPv4 client is enabled, the configured hostname
will be used in the DHCP option 12 field. When this value is empty string, the field use
the configured system name plus the latest three bytes of system MAC addresses as the
hostname.
DHCPv4 Fallback
The number of seconds for trying to obtain a DHCP lease. After this period expires, a
configured IPv4 address will be used as IPv4 interface address. A value of zero
disables the fall-back mechanism, such that DHCP will keep retrying until a valid lease
is obtained. Legal values are 0 to 4294967295 seconds.
DHCPv4 Current Lease
For DHCP interfaces with an active lease, this column shows the current interface
address, as provided by the DHCP server.
IPv4 Address
The IPv4 address of the interface in dotted decimal notation.
If DHCP is enabled, this field configures the fall-back address. The field may be left
blank if IPv4 operation on the interface is not desired - or no DHCP fall-back address
is desired.
IPv4 Mask Length
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0
and 30 bits for an IPv4 address.
If DHCP is enabled, this field configures the fall-back address network mask. The field
may be left blank if IPv4 operation on the interface is not desired - or no DHCP fall-
back address is desired.
DHCPv6 Enable
Enable the DHCPv6 client by checking this box. If this option is enabled, the system
will configure the IPv6 address of the interface using the DHCPv6 protocol.
DHCPv6 Rapid Commit
Enable the DHCPv6 Rapid-Commit option by checking this box. If this option is
enabled, the DHCPv6 client terminates the waiting process as soon as a Reply message
with a Rapid Commit option is received.
This option is only manageable when DHCPv6 client is enabled.
DHCPv6 Current Lease
For DHCPv6 interface with an active lease, this column shows the interface address
provided by the DHCPv6 server.
IPv6 Address
The IPv6 address of the interface. An IPv6 address is in 128-bit records represented as
eight fields of up to four hexadecimal digits with a colon separating each field (:). For
example, fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used
as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it
can appear only once.
System accepts the valid IPv6 unicast address only, except IPv4-Compatible address
and IPv4-Mapped address.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask Length
The IPv6 network mask, in number of bits (prefix length). Valid values are between 1
and 128 bits for an IPv6 address.
The field may be left blank if IPv6 operation on the interface is not desired.
The third part of IP Setting section is the IP Routes part as shown in Figure 2.9. Description of each field or option is
summarized in Table 2.4. Please click on the Save button to update the IP configuration on the switch. A system reboot is
