Chapter 1 Operation of Web-based Management
Initial
Configuration This chapter instructs you how to configure and manage the
RY-LGSO25-24 through the web user interface. With this facility, you can
easily access and monitor through any one port of the switch all the status of
the switch, including MIBs status, each port activity, Spanning tree status,
port aggregation status, multicast traffic, VLAN and priority status, even
illegal access record and so on.
The default values of the RY-LGSO25-24 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
admin
After the RY-LGSO25-24 has been finished configuration the it interface, you
can browse it. For instance, type http://192.168.1.1 in the address row in
a browser, it will show the following screen and ask you inputting username
and password in order to login and access authentication.
The default username is “admin”and password is “admin”. For the first
time to use, 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
RY-LGSO25-24 will not give you a shortcut to username automatically. This
looks inconvenient, but safer.
In the RY-LGSO25-24, allowed two or more users using administrator’s
identity to manage this switch, which administrator to do the last setting, it
will be an available configuration to effect the system.
NOTE:
When you login the Switch WEB/CLI to manager. You must first type
the Username of the admin. Password was blank, so when you
type after the end Username, please press enter. Management page
to enter WEB/CLI.
When you login RY-LGSO25-24 series switch Web UI management,
you can use both ipv4 ipv6 login to manage
To optimize the display effect, we recommend you use Microsoft IE
6.0 above, Netscape V7.1 above or FireFox V1.00 above and have
the resolution 1024x768. The switch supported neutral web browser

Chapter 2 System Configuration
This chapter describes the entire basic configuration tasks which includes the System
Information and any manage 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:

Parameter description:
System Contact:
The textual 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.

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.

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.
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. A 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 a 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
notationor 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 notationor 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.

Parameter description:
Mode :
Indicates the NTP mode operation. Possible modes are:
Enabled: Enable NTP client mode operation.
Disabled: Disable NTP client mode operation.
Server 1 to 5 :
Provide the NTP IPv4 or IPv6 address of this switch. 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 only appear once. It can
also represent a legally valid IPv4 address. For example, '::192.1.2.34'.
