Chapter 1 Operation of Web-based Management
Initial
Configuration
This chapter instructs you how to configure and manage the SG75270MP through
the web user interface.
The default access credentials of the SG75270MP are listed in the table below:
IP Address
192.168.1.1
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.254
Username
admin
Password
After the SG75270MP has been powered on and the initial boot sequence has loaded,
you can access the web-based management interface. For instance, type
http://192.168.1.1 in the address row in a browser, it will show the following screen
and ask you to enter the username and password.
The default username is “admin” and password field is left empty. When first
accessing the switch, please enter the default username and password, and then click
the <Login> button. The login process now is completed. In this login menu, you
have to input the complete username and password respectively, the SG75270MP will
not give you a shortcut to username automatically. This looks inconvenient, but it is
safer.
The SG75270MP allows two or more users using administrator credentials to manage
this switch.

NOTE:
As the SG75270MP enables DHCP, so if you do not have a DHCP server to
provide an IP address to the switch, the switch’s default IP is 192.168.1.1

Chapter 2 System Configuration
This chapter describes the entire basic configuration tasks which includes the System Information and
any management of the Switch (e.g. Time, Account, IP, Syslog and NTP.)
2-1 System
You can identify the system by configuring the contact information, name, and location of the
switch.
2-1.1 Information
The switch system’s contact information is provided here.
Web interface
To configure System Information in the web interface:

Figure 2-1.1: System Information
Parameter description:
System Contact:
The text identification of the contact person for this managed node, together with
information on how to contact this person. The allowed string length is 0 to 128, and the
allowed content is the ASCII characters from 32 to 126.
System name:
An administratively assigned name for this managed node. By convention, this is the node's
fully-qualified domain name. A domain name is a text string drawn from the alphabet
(A-Za-z), digits (0-9), minus sign (-). No space characters are permitted as part of a name.
The first character must be an alpha character. And the first or last character must not be a
minus sign. The allowed string length is 0 to 128.

2-1.2 IP
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page
Configure IP basic settings, control IP interfaces and IP routes.
The maximum number of interfaces supported is 8 and the maximum number of routes is 32.

Configure whether the IP stack should act as a Host or a Router. In Host mode, IP traffic
between interfaces will not be routed. In Router mode traffic is routed between all
interfaces.
DNS Server
This setting controls the DNS name resolution done by the switch. The following modes are
supported:
From any DHCP interfaces
The first DNS server offered from a DHCP lease to a DHCP-enabled interface will be
used.
No DNS server
No DNS server will be used.
Configured
Explicitly provide the IP address of the DNS Server in dotted decimal notation.
From this DHCP interface
Specify from which DHCP-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.
IP Interfaces
Delete
Select this option to delete an existing IP interface.
VLAN
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.
IPv4 DHCP Enabled
Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.
IPv4 DHCP Fallback Timeout
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
fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal
values are 0 to 4294967295 seconds.
IPv4 DHCP Current Lease
For DHCP interfaces with an active lease, this column show 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 is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
IPv4 Mask
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and 30
bits for a IPv4 address.
9
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
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.
It can also represent a legally valid IPv4 address. For example, ::192.1.2.34.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask
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.
IP Routes
Delete
Select this option to delete an existing IP route.
Network
The destination IP network or host address of this route. Valid format is dotted decimal
notation or a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 :: notation.
Mask Length
The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values
are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).
Gateway
The IP address of the IP gateway. Valid format is dotted decimal notation or a valid IPv6
notation. Gateway and Network must be of the same type.
Next Hop VLAN (Only for IPv6)
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway.
The given VID ranges from 1 to 4094 and will be effective only when the corresponding IPv6
interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.

2-1.3 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform
time sync via NTP because the switch will combine this time zone offset and updated NTP time
to come out the local time, otherwise, you will not able to get the correct time. The switch
supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
Web Interface
To configure NTP in the web interface:
1. Click Configuration, System, NTP.
2. Specify the Time parameter in manual parameters.
3. Click Apply.
