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 Firefox, Microsoft Internet Explorer, Mozilla, or Netscape. 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.

Login to Web Manager

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.

Figure 1 - 1 Enter Network Password dialog

Enter “admin” in both the User Name and Password fields and click OK. This will open the Web-based user interface. The Switch management features available in the web-based manager are explained below.

xStack® DES-3200-10/18/28/28F Layer 2 Ethernet Managed Switch User Manual

Web-based User Interface

The user interface provides access to various Switch configuration and management windows, allows you to view performance statistics, and permits you to graphically monitor the system status.

Areas of the User Interface

The figure below shows the user interface. The user interface is divided into three distinct areas as described in the table.

Area 1

Figure 1 - 2 Main Web-Manager page

Area Function

Area 1 Select the folder or window to be displayed. The folder icons can be opened to display the hyperlinked window buttons and subfolders contained within them. Click the D-Link logo to go to the D-Link website.

Area 2 Presents a graphical near real-time image of the front panel of the Switch. This area displays the Switch's ports and expansion modules, showing port activity, duplex mode, or flow control, depending on the specified mode.

Various areas of the graphic can be selected for performing management functions, including port configuration.

Area 3

Presents switch information based on your selection and the entry of configuration data.

NOTICE: Any changes made to the Switch configuration during the current session must be saved in the Save Configuration window (Save > Save Configuration) or use the command line interface (CLI) command save config.

xStack® DES-3200-10/18/28/28F Layer 2 Ethernet Managed Switch User Manual

If VLANs have been previously configured on the Switch, the Management VLAN Name of the VLAN that contains the port connected to the management station will have to be entered to access the Switch.

5.Use the drop-down Interface Admin State menu to select Enabled if it has not already been done.

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 either BOOTP or DHCP.

		xStack® DES-3200-10/18/28/28F Layer 2 Ethernet Managed Switch User Manual
	The IP Address Settings options are:

	Parameter	Description

	Static	Allows the entry of an IPv4 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	The current IP Interface being assigned an IP address on this window.

	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	Toggle between Enabled and Disabled. This must be set to Enabled when setting an IP address
	State	on this window.

	IPv4 Address	Enter the desired IPv4 address to be set. The default address is 10.90.90.90.

	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.

	DHCP Option 12	Use to enable or disable DHCP Option 12.
	State

	DHCP Option 12	Type the name of the host used for Option 12. Up to 63 characters are allowed.
	Host Name

Port Configuration

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

Port Settings

Various port settings, including State, Speed/Duplex, Flow Control, Address Learning, Medium Type, and MDIX can be configured on the Switch.

To view the following window, click Configuration > Port Configuration > Port Settings:

Figure 2 - 8. Port Settings window

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

		xStack® DES-3200-10/18/28/28F Layer 2 Ethernet Managed Switch User Manual

	Parameter	Description

	From Port/To	Use the pull-down menus to select the port or range of ports to be configured.
	Port
	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_Master, 1000M Full_Slave 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_Master and 1000M Full_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_Master) 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_Slave) uses
		loop timing, where the timing comes from a data stream received from the master. If one
		connection is set for 1000M Full_Master, the other side of the connection must be set for 1000M
		Full_Slave. 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	When Enabled, destination and source MAC addresses are automatically listed in the forwarding
	Learning	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.
	MDIX	This can be specified as Auto, Normal, or Cross. In Normal state, the port is in MDIX mode and
		can be connected to a PC NIC using a straight cable. If it is in Cross state, the port is in MDI
		mode, and can be connected to a port (in MDIX mode) on another switch through a straight
		cable.

Click Apply to implement the new settings on the Switch.

DHCP Relay

The relay hops count limit allows the maximum number of hops (routers) that the DHCP messages can be relayed through to be set. If a packet’s hop count is equal to or more than the hop count limit, the packet is dropped. The range is between 1 and 16 hops, with a default value of 4. The relay time threshold sets the minimum time (in seconds) that the Switch will wait before forwarding a BOOTREQUEST packet. If the value in the seconds field of the packet is less than the relay time threshold, the packet will be dropped. The range is between 0 and 65,535 seconds, with a default value of 0 seconds.

DHCP Relay Global Settings

To enable and configure DHCP Relay Global Settings on the Switch, click Configuration > DHCP Relay > DHCP Relay Global Settings:

Threshold (0-65535)

DHCP Relay Agent

Information Option 82

State

This field can be toggled between Enabled and Disabled using the pull-down menu. It is used to enable or disable the DHCP Relay service on the Switch. The default is Disabled

This field allows an entry between 1 and 16 to define the maximum number of router hops DHCP messages can be forwarded across. The default hop count is 4.

Allows an entry between 0 and 65535 seconds, and defines the maximum time limit for routing a DHCP packet. If a value of 0 is entered, the Switch will not process the value in the seconds field of the BOOTP or DHCP packet. If a non-zero value is entered, the Switch will use that value, along with the hop count to determine whether to forward a given BOOTP or DHCP packet.

This field can be toggled between Enabled and Disabled using the pull-down menu. It is used to enable or disable the DHCP Agent Information Option 82 on the Switch. The default is Disabled.

Enabled – When this field is toggled to Enabled the relay agent will insert and remove DHCP relay information (option 82 field) in messages between DHCP servers and clients. When the relay agent receives the DHCP request, it adds the option 82 information, and the IP address of the relay agent (if the relay agent is configured), to the packet. Once the option 82 information has been added to the packet it is sent on to the DHCP server. When the DHCP server receives the packet, if the server is capable of option 82, it can implement policies like restricting the number of IP addresses that can be assigned to a single remote ID or circuit ID. Then the DHCP server echoes the option 82 field in the DHCP reply. The DHCP server unicasts the reply to the back to the relay agent if the request was relayed to the server by the relay agent. The switch verifies that it originally inserted the option 82 data. Finally, the relay agent removes the option 82 field and forwards the packet to the switch port that connects to the DHCP client that sent the DHCP request.

Disabled - If the field is toggled to Disabled the relay agent will not insert and remove DHCP relay information (option 82 field) in messages between DHCP servers and clients, and the

check and policy settings will have no effect.

This field can be toggled between Enabled and Disabled using the pull-down menu. It is used to enable or disable the Switches ability to check the validity of the packet’s option 82 field.

Enabled – When the field is toggled to Enable, the relay agent will check the validity of the packet’s option 82 field. If the switch receives a packet that contains the option-82 field from a DHCP client, the switch drops the packet because it is invalid. In packets received from DHCP servers, the relay agent will drop invalid messages.

Disabled - When the field is toggled to Disabled, the relay agent will not check the validity of the packet’s option 82 field.

This field can be toggled between Replace, Drop, and Keep by using the pull-down menu. It is used to set the Switches policy for handling packets when the DHCP Agent Information Option 82 Check is set to Disabled. The default is Replace.

Replace - The option 82 field will be replaced if the option 82 field already exists in the packet received from the DHCP client.

Drop - The packet will be dropped if the option 82 field already exists in the packet received from the DHCP client.

Keep -The option 82 field will be retained if the option 82 field already exists in the packet received from the DHCP client.

This field is for you to enter the remote ID. Tick Default to use the Switch’s system MAC address as the remote ID.

Click Apply to implement any changes that have been made.

NOTE: If the Switch receives a packet that contains the option-82 field from a DHCP client and the information-checking feature is enabled, the switch drops the packet because it is invalid. However, in some instances, you might configure a client with the option-82 field. In this situation, you should disable the information-check feature so that the switch does not remove the option-82 field from the packet. You can configure the action that the switch takes when it receives a packet with existing option-82 information by configuring the DHCP Agent Information Option 82 Policy.

The Implementation of DHCP Information Option 82 on the Switch

The config dhcp_relay option_82 command configures the DHCP relay agent information option 82 setting of the switch. The formats for the circuit ID sub-option and the remote ID sub-option are as follows:
