Chapter 1 Operation of Web-based Management

Initial

Configuration

This chapter instructs you how to configure and manage the GEPoEL2P-ESW26G

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.

T

he default values of GEPoEL2P-ESW26G 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 GEPoEL2P-ESW26G 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 empty. 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 GEPoEL2P-ESW26G will not give

you a shortcut to username automatically. This looks inconvenient, but safer.

In GEPoEL2P-ESW26G, 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.

 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.

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.
