Web-based Switch Configuration

Introduction

Login to Web Manager

Web-based User Interface

Web Pages

Introduction

All software functions of the Switch can be managed, configured and monitored via the embedded web-based (HTML) interface. The Switch can be managed from remote stations anywhere on the network through a standard browser such as Opera, Netscape Navigator/Communicator, or Microsoft Internet Explorer. The browser acts as a universal access tool and can communicate directly with the Switch using the HTTP protocol.

The Web-based management module and the Console program (and Telnet) are different ways to access the same internal switching software and configure it. Thus, all settings encountered in web-based management are the same as those found in the console program.

To begin managing the Switch, simply run the browser you have installed on your computer and point it to the IP address you have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where the numbers 123 represent the IP address of the Switch.

NOTE: The Factory default IP address for the Switch is 10.90.90.90.

This opens the management module's user authentication window, as seen below.

IP Address

The IP address may initially be set using the console interface prior to connecting to it through the Ethernet. If the Switch IP address has not yet been changed, read the introduction of the DGS-3700 Series CLI Manual for more information.

To view this window, click Configuration > IP Address as shown below:

Figure 2 - 4 IP Address Settings window

The upper part of the page allows you to manually assign the Switch's IP address, subnet mask, and default gateway address:

1.Select Static at the top of the screen.

2.Enter the appropriate IP Address and Subnet Mask.

3.If you want to access the Switch from a different subnet from the one it is installed on, enter the IP address of the Gateway. If you will manage the Switch from the subnet on which it is installed, you can leave the default address (0.0.0.0) in this field.

4.If no VLANs have been previously configured on the Switch, you can use the default VLAN Name. The default VLAN contains all of the Switch ports as members. If VLANs have been previously configured on the Switch, you will need to enter the Management VLAN Name of the VLAN that contains the port connected to the management station that will access the Switch. The Switch will allow management access from stations with the same VID listed here.

NOTE: The Switch's factory default IP address is 10.90.90.90 with a subnet mask of 255.0.0.0 and a default gateway of 0.0.0.0.

To use the BOOTP or DHCP protocols to assign the Switch an IP address, subnet mask, and default gateway address:

Select BOOTP or DHCP, this will determine how the Switch will be assigned an IP address.

The lower part of the page is to display the Out-of-band management information that has been configured in

Configuration > Out of Band Management Settings window.

The IP Address Settings options are:

		DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual

	Parameter	Description

	Static	Allows the entry of an IP address, Subnet Mask, and a Default Gateway for the Switch. These
		fields should be of the form xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal
		form) between 0 and 255. This address should be a unique address on the network assigned for
		use by the network administrator.
	DHCP	The Switch will send out a DHCP broadcast request when it is powered up. The DHCP protocol
		allows IP addresses, network masks, and default gateways to be assigned by a DHCP server. If
		this option is set, the Switch will first look for a DHCP server to provide it with this information
		before using the default or previously entered settings.
	BOOTP	The Switch will send out a BOOTP broadcast request when it is powered up. The BOOTP
		protocol allows IP addresses, network masks, and default gateways to be assigned by a central
		BOOTP server. If this option is set, the Switch will first look for a BOOTP server to provide it with
		this information before using the default or previously entered settings.
	IP Interface	This field displays the IP Interface that is currently being used on the Switch.

	Management	This allows the entry of a VLAN Name from which a management station will be allowed to
	VLAN Name	manage the Switch using TCP/IP (in-band via web manager or Telnet). Management stations that
		are on VLANs other than the one entered here will not be able to manage the Switch in-band
		unless their IP addresses are entered in the Security IP Management window. If VLANs have
		not yet been configured for the Switch, the default VLAN contains all of the Switch's ports. There
		are no entries in the Security IP Management table, by default, so any management station that
		can connect to the Switch can access the Switch until a management VLAN is specified or
		Management Station IP Addresses are assigned.

	Interface Admin	This field enables or disables the Interface Admin State. When the state is enabled, the IPv4
	State	processing will be started when the IPv4 address is configured on the IPIF. The IPv6 processing
		will be started when the IPv6 address is explicitly configured on the IPIF.

	IPv4 Address	The address should specify a host address and length of the network prefix. There can be
		multiple IPv4 addresses defined on an interface. Thus, as a new address is defined, it is added on
		this IP Interface.

	Subnet Mask	A Bitmask that determines the extent of the subnet that the Switch is on. Should be of the form
		xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal) between 0 and 255. The
		value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and
		255.255.255.0 for a Class C network, but custom subnet masks are allowed.

	Gateway	IP address that determines where packets with a destination address outside the current subnet
		should be sent. This is usually the address of a router or a host acting as an IP gateway. If your
		network is not part of an Intranet, or you do not want the Switch to be accessible outside your
		local network, you can leave this field unchanged.

DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual

Setting the Swith’s IP Address using the Console Interface

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your networking address scheme.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known. The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy, where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.

Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z, where the x’s represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

The system message Success indicated that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management agent using the above ip address to connect to the Switch.

Port Configuration

This section contains information for configuring various attributes and properties for individual physical ports, including port speed and flow control.

Port Settings

To view this window, click Configuration > Port Configuration > Port Settings as shown below:

To configure switch ports:

Choose the port or sequential range of ports using the From Port / To Port port pull-down menus. Use the remaining pull-down menus to configure the parameters described below:

Figure 2 - 11 Port Settings window

The following parameters can be configured:

DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual

	Parameter	Description

	From Port / To Port	Use the pull-down menus to select the port or range of ports to be configured.

	State	Toggle this field to either enable or disable a given port or group of ports.

	Speed/Duplex	Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the
		port. Auto denotes auto-negotiation between 10 and 100 Mbps devices, in fullor half-duplex.
		The Auto setting allows the port to automatically determine the fastest settings the device the
		port is connected to can handle, and then to use those settings. The other options are Auto,
		10M/Half, 10M/Full, 100M/Half and 100M/Full, 1000M/Full_M, 1000M/Full_S and 1000M/Full.
		There is no automatic adjustment of port settings with any option other than Auto.
		The Switch allows the user to configure two types of gigabit connections; 1000M/Full_M and
		1000M/Full_S. Gigabit connections only support full duplex connections and take on certain
		characteristics that are different from the other choices listed.
		The 1000M/Full_M (master) and 1000M/Full_S (slave) parameters refer to connections
		running a 1000BASE-T cable for connection between the Switch port and other device
		capable of a gigabit connection. The master setting (1000M/Full_M) will allow the port to
		advertise capabilities related to duplex, speed and physical layer type. The master setting will
		also determine the master and slave relationship between the two connected physical layers.
		This relationship is necessary for establishing the timing control between the two physical
		layers. The timing control is set on a master physical layer by a local source. The slave
		setting (1000M/Full_S) uses loop timing, where the timing comes form a data stream
		received from the master. If one connection is set for 1000M/Full_M, the other side of the
		connection must be set for 1000M/Full_S. Any other configuration will result in a link down
		status for both ports.

	Flow Control	Displays the flow control scheme used for the various port configurations. Ports configured
		for full-duplex use 802.3x flow control, half-duplex ports use backpressure flow control, and
		Auto ports use an automatic selection of the two. The default is Disabled.

	Address Learning	When Enabled, destination and source MAC addresses are automatically listed in the
		forwarding table. The default setting is Enabled.

	Medium Type	This applies only to the Combo ports. If configuring the Combo ports this defines the type of
		transport medium used. SFP ports should be set at Fiber and the Combo 1000BASE-T ports
		should be set at Copper.

Click Apply to implement the new settings on the Switch. Click Refresh to reload the page.

Port Description

The Switch supports a port description feature where the user may assign names to various ports on the Switch.

Use the From Port / To Port pull-down menu to choose a port or range of ports to describe, and then enter a description of the port(s). Click Apply to set the descriptions in the Port Description Table.

The Medium Type applies only to the Combo ports. If configuring the Combo ports this defines the type of tranport medium used. SFP ports should be nominated Fiber and the Combo 1000BASE-T ports should be nominated Copper. The result will be displayed in the appropriate switch port number slot (C for copper ports and F for fiber ports).
