Web-based Switch Configuration

Introduction Login to Web Manager Web-based User Interface Web Pages

Introduction

All software functions of the Switch can be m anag ed, configured and m onitore d via the embedde d we b-bas e d (H T ML) interface. The Switch c an be managed from remote s tations anywhere on the network thr ough a standard browser such as Opera, Netscape Navigator/Communicator, or Micros oft Internet Explorer. The browser acts as a uni versal access tool and can communicate directly with the Switch using the HTTP protocol.
The Web-based m anagement module and the Cons ole program (and Telnet) are dif ferent ways to access the sam e internal switching s oftware and conf igure it. Thus, al l settings encount ered in web-based management ar e 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 com puter 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 ma y initially be set using the console interface prior to connecting to it throug h the Ethernet. If the Switch IP address has not yet been change d, 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 pag e allows you to manual ly assign the S witch's IP a ddress , subnet m ask, and defaul t gatewa y address:
1. Select Static at the top of the screen.
2. Enter the appropriate IP Address and Subnet Mas k .
3. If you want to access the Switch from a dif fer ent subn et fr om the on e it is insta lled on, enter the I P addr ess of the Gateway. If you will m anage t he Switc h fr om the subne t on which it is insta lled, you can leave th e defaul t address (0.0.0.0) in this field.
4. If no VLANs have been pre vious ly configured on the Sw itch, you can use the default VLAN Name. The default VLAN c ontains all of the Switch p orts as m embers. If VLANs have been pr eviously conf igured on the S witch, you will need to enter the Management VLAN Name of the VLAN that contains the port connected to the management station th at will acc ess the Switc h. The S witch will a llow managem ent acc ess fr om stations wi th 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:

IP Interface
Management VLAN Name
State
Allows the entry of an IP address, Subnet Mask, and a Def ault Gateway for the Switch. Thes e fields should be of the form xxx. xxx.xxx.xxx , where each x xx is a num ber (represente d in decim al form) between 0 and 2 55. This address should be a unique addr ess on the n etwork assigned for use by the network administrator.
The Switch will sen d out a DHCP broadcas t request when it is powered up. T he DHCP pro tocol allows IP address es, network masks, and defaul t gateways to be assigned b y a DHCP server . If this option is set, the Sw itch will first look for a DHCP server to provide it with this information before using the default or previously entered settings.
The Switch will send out a BOOTP broadcast request when it is powered up. The BOOTP protocol allows IP addr esses, network masks , and default gateways to be assigned b y a central BOOTP server. If t his optio n is set, the S witch will first lo ok f or a BOOT P server t o provide it with this information before using the default or previously entered settings.
This field displays the IP Interface that is currently being used on the Switch. This allows the entry of a VLAN Name from which a management station will be allowed to
manage the Switch usin g TCP/IP (in-band via web manager or Telne t). M anagement stations th at are on VLANs other than the one entered here will not be able to m anage the Switch in-band unless their IP address es are entered in the Securit y IP Management window. If VLANs have not yet been configur ed for the Switch, t he default VL AN contains all of the Switc h's ports. Ther e are no entries in th e Security IP Mana gement table, by d efault, so any m anagement station that can connect to the Switch can access the Switch until a management VLAN is specified or Management Station IP Addresses are assigned.
This field enables or disables the Interface Admin State. When the state is enabled, the IPv4 processing will be start ed when the IPv4 addr ess is configured on t he IPIF. The IPv6 proc essing 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 determ ines the extent of the subnet that the S witch is on. Shoul d be of the form xxx.xxx.xxx.xx x, where each xxx is a number (repr esented in decimal) bet ween 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 determ ines where pack ets with a destination a ddress outside th e current subnet should be sent. This is usually the address of a rout er or a host ac ting as an IP gate way. If your network is not part of an Intranet, or you do not want the S witch to be accessible outside your local network, you can leave this field unchanged.

Setting the Swith’s IP Address using the Console Interface

Each Switch must be ass igned its own I P Address, which is used for c omm unication with an SN MP network m anager 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 W eb-based manager. The Swit ch IP address can be aut omaticall y set usin g BOOT P or DHCP protocols , in wh ich cas e the actu al addres s assigned to the Switch must be known. T he IP address may be set using the C ommand Line Interfac e (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 ag ent us ing th e abo ve ip addr ess to connect to the Switch.

The Switch allows the us er to config ure two types of gigabit connec tions; 1000M/Full_M and 1000M/Full_S. G igabit connections on ly support full duplex connect ions 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) advertise capabilities r elat e d to du pl ex, s peed and physical layer type. T he master setting will also determine the m aster and sla ve relat ionship b etween th e t wo connected ph ysical la yers. 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 m aster. If one connection is set f or 1000M/Full_M, the other side of the connection mus t be set for 1000M/Full_S. An y other configuration will result in a link down status for both ports.
