Initial Configuration

This chapter instructs you how to configure and manage the GEL-2681 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 GEL-2681 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 GEL-2681 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 GEL-2681 will not give you a shortcut to username automatically. This looks

inconvenient, but safer.

In the GEL-2681, 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 GEL-2681 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

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:

Click Configuration, System, and Information.

Write System Contact, System Name, System Location information in this page.

Click Apply

Figure 2-1.1: System Information

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.

 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:

Click Configuration, System, IP.

Click Add Interface then you can create new Interface on the switch.

Click Add Route then you can create new Route on the switch

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. 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 an 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. 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.

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. 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 configure a Port Power Saving Configuration in the web interface:

Click Configuration, Green Ethernet

Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues .

Click Apply.

Figure 2-2.1: The Port Power Saving Configuration

Parameter description:

Optimize EEE for

The switch can be set to optimize EEE for either best power saving or least traffic latency.

Port:

The switch port number of the logical port.

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.

PerfectReach :

Cable length power savings enabled.

PerfectReach works by determining the cable length and lowering the power for ports with short cables.

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.

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.

red that it is down.

Current Link Speed :

Provides the current link speed of the port.

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.

1000-X - SFP port in 1000-X speed. Cu port disabled.

1000-X_AMS - Port in AMS mode. SFP port in 1000-X speed. Cu port in Auto mode. Ports in AMS mode with 1000-X speed has Cu port preferred. Ports in AMS mode with 100-FX speed has fiber port preferred.

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.
