Initial
Configuration
This chapter instructs you how to configure and manage the GEP-2651 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 GEP-2651 are listed in the table below:
After the GEP2651 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 GEP-2651 will not give you a shortcut to
username automatically. This looks inconvenient, but safer.
In the GEP-2651, 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.

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.
l 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.
l 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.
l 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
l Delete
Select this option to delete an existing IP interface.
l 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 an new interface.
l 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.
l 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 disa bles the
fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal
values are 0 to 4294967295 seconds.
l IPv4 DHCP Current Lease
For DHCP interfaces with an active lease, this column show the current interface address,
as provided by the DHCP server.
l 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.
l 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.
l 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.
Revision A1

notationor a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 ::
notation.
l 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).
l 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.
l 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.

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'.

l Server Mode :
Indicate the server mode operation. When the mode operation is enabled, the syslog
message will send out to syslog server. The syslog protocol is based on UDP communication
and received on UDP port 514 and the syslog server will not send acknowledgments back
sender since UDP is a connectionless protocol and it does not provide acknowledgments.
The syslog packet will always send out even if the syslog server does not exist. Possible
modes are:
Enabled: Enable server mode operation.
Disabled: Disable server mode operation.
l Server Address :
Indicates the IPv4 hosts address of syslog server. If the switch provide DNS feature, it also
can be a host name.

2-2 Green Ethernet
EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.
EEE works by powering down circuits when there is no traffic. When a port gets data to be
transmitted all circuits are powered up. The time it takes to power up the circuits is named
wakeup time. The default wakeup time is 17 us for 1Gbit links and 30 us for other link speeds.
Revision A1
15
EEE devices must agree upon the value of the wakeup time in order to make sure that both the
receiving and transmitting device has all circuits powered up when traffic is transmitted. The
devices can exchange wakeup time information using the LLDP protocol.
EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100
Mbit full duplex mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and
thus impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.
Web Interface
To c o nf ig u re a P o rt P o we r S av in g C on f ig ur at i on i n t he w eb in te r fa ce :
1. Click Configuration, Green Ethernet
2. Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues .
3. Click Apply.

The switch can be set to optimize EEE for either best power saving or least traffic latency.
l Port:
The switch port number of the logical port.
Revision A1

l ActiPHY :
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is power up
for short moment in order to determine if cable is inserted.
l PerfectReach :
Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for ports with
short cables.
l EEE :
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is ready for a
port, but is instead queued until a burst of data is ready to be transmitted. This will give some
traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the frames to
a specific queue (done with QOS), and then mark the queue as an urgent queue. When an
urgent queue gets data to be transmitted, the circuits will be powered up at once and the
latency will be reduced to the wakeup time.
l EEE Urgent Queues :
Queues set will activate transmission of frames as soon as data is available. Otherwise the
queue will postpone transmission until a burst of frames can be transmitted.

l Configured Link Speed :
Selects any available link speed for the given switch port. Only speeds supported by the
specific port is shown. Possible speeds are:
Disabled - Disables the switch port operation.
Auto - Port auto negotiating speed with the link partner and selects the highest speed that is
compatible with the link partner.
10Mbps HDX - Forces the cu port in 10Mbps half duplex mode.
10Mbps FDX - Forces the cu port in 10Mbps full duplex mode.
100Mbps HDX - Forces the cu port in 100Mbps half duplex mode.
100Mbps FDX - Forces the cu port in 100Mbps full duplex mode.
1Gbps FDX - Forces the port in 1Gbps full duplex
2.5Gbps FDX - Forces the Serdes port in 2.5Gbps full duplex mode.
SFP_Auto_AMS - Automatically determines the speed of the SFP. Note: There is no
standardized way to do SFP auto detect, so here it is done by reading the SFP rom. Due to
the missing standardized way of doing SFP auto detect some SFPs might not be detectable.
The port is set in AMS mode. Cu port is set in Auto mode.
100-FX - SFP port in 100-FX speed. Cu port disabled.
100-FX_AMS - Port in AMS mode. SFP port in 100-FX speed. Cu port in Auto mode.

speed has fiber port preferred.
l Flow Control :
When Auto Speed is selected on a port, this section indicates the flow control capability that
is advertised to the link partner. When a fixed-speed setting is selected, that is what is used.
The Current Rx column indicates whether pause frames on the port are obeyed, and the
Current Tx column indicates whether pause frames on the port are transmitted. The Rx and
Tx settings are determined by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the setting for
Configured Link Speed.
