Chapter 1 Operation of Web-based Management
Initial
Configuration
This chapter instructs you how to configure and manage the IGP-1271 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 IGP-1271 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 IGP-1271 has been finished configuration 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 IGP-1271 will not give you a
shortcut to username automatically. This looks inconvenient, but safer.
In the IGP-1271, 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 page to manage. You must first type the
Username of the admin. Password was admin., so when you type after the
end Username, please press enter. Management page to enter WEB.
When you login IGP-1271 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 interface

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 255.
System Location:
The physical location of this node(e.g., telephone closet, 3rd floor). The allowed string
length is 0 to 128, and the allowed content is the ASCII characters from 32 to 126.

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.
Web Interface
To configure an IP address in the web interface:
1. Click Configuration, System, IP.
2. Click Add Interface then you can create new Interface on the switch.
3. Click Add Route then you can create new Route on the switch
4. Click Apply
Figure2-1.2: The IP configuration

Parameter description:
IP Configuration
Mode:
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.
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.
System selects the active DNS server from configuration in turn, if the preferred server does
not respond in five attempts.
The following modes are supported:
From any DHCP interfaces
The first DNS server offered from a DHCPv4 lease to a DHCPv4-enabled interface will
be used..
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.
From this DHCPv4 interface
Specify from which DHCPv4-enabled interface a provided DNS server should be
preferred.
Configured IPv6
Explicitly provide the valid IPv6 unicast (except linklocal) address of the DNS Server.
Make sure the configured DNS server could be reachable (e.g. via PING6) for activating
DNS service.
From this DHCPv6 interface
Specify from which DHCPv6-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.
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.
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

9
interface. This field is only available for input when creating a new interface.
IPv4 DHCP 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. The DHCPv4 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 configures the fallback address. The field may be left blank if IPv4
operation on the interface is not desired - or no DHCP fallback address is 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 configures the fallback address network mask. The field may be left
blank if IPv4 operation on the interface is not desired - or no DHCP fallback 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. 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.
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
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.
Resolving IPv6 DAD
The link-local address is formed from an interface identifier based on the hardware address which

10
is supposed to be uniquely assigned. Once the DAD (Duplicate Address Detection) detects the
address duplication, the operation on the interface SHOULD be disabled.
At this moment, manual intervention is required to resolve the address duplication. For example,
check whether the loop occurs in the VLAN or there is indeed other device occupying the same
hardware address as the device in the VLAN.
After making sure the specific link-local address is unique on the IPv6 link in use, delete and then
add the specific IPv6 interface to restart the IPv6 operations on this interface.
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 4095 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.

11
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.
Figure 2-1.3: The NTP configuration
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 IPv4 or IPv6 address of a NTP server. 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'. In addition, it can also accept a domain name address.
