4. WEB-BASED MANAGEMENT This section introduces the configur ation and functions of the Web-Based management. 4.1 About W eb-based Management The switch offers management features that allow users to manage the switch from anywhere on the network through a standard bro wser such as Microsoft Internet Explorer .
WGSW-2840 Web Management Interface 4.4 System 4.4.1 IP Configuration The switch can be managed by the Web/T elnet/S NMP interfaces. Administrators can access the management interface via the IP address of the swit ch. The default IP address of the switch is 192.
NOTE: 1. T he Switch’s factory -default IP address is 19 2.168.0.100 with Submask 25 5.255.255.0 a nd a default gateway of 192.168.0.254 2. T he changed IP address take effect immediately af ter click on the OK button, you need t o use the new IP address to access the W eb interface.
message is designed to replace the SNMPv 1 trap message. SNMP community An SNMP community is the group that devices and management stations runn ing SNMP belong to. It helps define where information is sent. The community name is used to identif y the group.
This table is to define the system name, system location and the contact person of the switch. These informations show in the SNMP software of the ma nagement workstation which helps to identify the switch that is looking into.
4. Management S tat ion Configuration A trap manage r is a management station (SNMP applic ation) that receives traps (the system alerts generated by the switch). If no trap manager is def ined, no traps are issued. Create a trap manager b y entering the IP address of the st ation and a community string.
4.4.3 Password The Passwo rd management menu is to set or change the pa ssword of the Web Management Interface. Click on System/Passwo rd menu button, and the Modify Password table shows in the main web page. Enter “old p assword “ , “new password” , “con f irm password” Click “OK” to change the password.
CAUTION: Do not power off the sw itch until the upd ate progress is complete. 4.4.6 Saving Parameters It takes effect i mmediately when you change the parameters of the manag ement function when the switch is running. But the parameters would not be saved after reboot the sw ith.
T o backup the runn ing conf iguration, click on the “Backu p the system’ s p arameters” link, and a pop up window shows to save the configuration of the s witch to your workstation. T o recover a saved config uration, click on the “Browse” button in the Par ameters Recovery table.
4.5 Port Management 4.5.1 Port Configuration This function is to configure and to vie w the configured port management status, port negotiation mode and the port flow control function. 。 Management S tatus : Display port status: Enable or Disab le. Disable is to turn off the port.
4.5.3 Port Band Restrict The function provides the In-B and and Out-Band conn ection speed restriction on the ports. The Band of the connection speed rangs from 64Kbps to 80000Kbps. Ingress Port List/Egress Port L i st field can be filled in distinct number or a port range.
4.6 Redundancy 4.6.1 S p anning T ree 1. Sp anning T ree Protocol The IEEE 802.1D S panning T ree Protocol and IEEE 802. 1W Rapid Sp anning Tree Protocol allow for the blocking of links bet ween switches that form loops within the network. When multiple links bet ween switches are detected, a primar y link is establish ed.
The communication bet ween switches via BPDUs results in the following: 。 One switch is elected as the root switch 。 The shortest distance to the root sw itch is calculated for each switch 。 A designate d switch is selected. This is the switch closest to the root switch through which packet s will be forwarded to the root.
。 From listening to learning or to disabled 。 From learning to for warding or to disabled 。 From forwarding to disabled 。 From disabled to blocking Switch Blocking Listening Learning Forwarding Disable STP Port S tate T ransitions Y ou can modify each port state by using management software.

parameters in the Switch are as follows: Priority – A Priority for the switch can be set from 0 to 65535. 0 is equal to t he highest Priority . Hello Time – The Hello T ime can be from 1 to 10 seconds.
Bridge ID = 15 Port 3 Port 1 Port 2 A Bridge ID = 20 Port 1 Port 2 Port 3 C Bridge ID = 30 Port 1 Port 2 Port 3 B LAN 1 LAN 2 LAN 3 Portcast = 19 Portcast = 19 Portcast = 19 Portcast = 4 Portcast = 4 Portcast = 19 Portcast = 4 Portcast = 4 Before Applying the ST A Rules In this example, only the default STP values are used.
between switch B and C is deliberate ly chosen as a 100 Mbps Fast Ethernet link (default port cost = 19). Gigabit ports could be used, but the port cost should be increased from t he default to ensure that the link between switch B and s witch C is the blocked link.
the default setting is 128.The lo wer number has the highest priority . Path Cost: S pecifies the path cost of the port. The switch uses this parameter to help determine which port will become a for warding port. Lower numbers will be used as forwarding ports first.
It allows a maximum of eight ports to be aggregated at the same time. The Sw itch support Gigabit Ethernet ports (up to 12 groups). If the group is defined as a LACP static link aggregationing group, then any extra ports selected are placed in a standby mode fo r redundancy if one of the other ports fails.
applications, which are sensiti ve to even slight delays, or for data from specified end user s whose data transmissions warrant special consideratio n. The Switch allows you to further tailor how priority tagged data packets are handled on your network.
new VLAN is created, the member ports assigned to the new VLAN will be removed from the DEF AUL T _ VLAN port member list. The DEF AUL T_VLAN has a VID = 1.
MAC address. Their presence is indicated by a value of 0x8100 i n the Ether T ype field. When a packet's Ether T ype field is equal to 0x8100, the packet ca rries the IEEE 802.
decisions are based upon this PVID, in so far as VLAN are concerned. T agged packet s are forwarded according to the VID contained within the tag. T agged packets are also assigned a PVID, but the PVID is not used to make packet forwarding decisions, the VID is.
2. The main page then change to Port-base VLAN table, click on the “A dd/Modify” button to create a new VLAN group. 3. The Port-ba se VLAN Confiruta tion table then pops up, enter the VLAN group ID, VLAN name and select the member ports for the VLAN.
802.1Q VLAN There are up to 256 configur able VLAN groups. By default when 802.1Q is enabled, all p orts on the switch belong to default VLAN (VID 1). The default VLAN cannot be deleted. Underst and nomenclature of the S w itch T agging and Untagging Every port on an 802.
Switch allows each port to set one PVID, the range is 1~255, default PVID is 1. The PVID must be the same as the VLAN ID that the por t was defined as belonging to in t he VLAN group, or the untagged traffic will be dropped. 1. Select 802.1Q VLAN in the VLAN T ype field and click on the “OK” button.
3. Choose the Link T ype in the drop drop down menu: A cces s or T runk . Note that if the Acces s type is chosen, it will strip the 802.1 Q t ag from all packets that out of this port.

4.7.5 MAC Address Aging T ime The Aging T ime affects the learning process of the S w itch. Dynamic forwarding table entries, which are made up of the source and destination MAC addr esse s and their associated port numbers, are deleted from the table if they are not accessed within the aging time.
4.8 QoS 4.8.1 Underst and QOS Quality of Service (QoS) is an advanced traffic prioriti zation feature that a llows you to establish control over network traffic. QoS enables you to assign various gr ades of network service to different types of traffic, such as multi-media, video, protocol-s pecific, time critical, and file-backup traffic.
Rules are associated with a QoS Profile (see above). T o implement QoS on your network, you need to carry out the follo wing actions: 1. Define a service level to determine the pr iority that will be applied to traffic. 2. Apply a classifier to determine how the incoming traffic will be classified and thus treated by the Swi tch.
2. VLAN-COS Mapping QoS settings allow customization of VLAN ID to T raffic classifiers 1. Fill the VID (1-2094) field in the VL AN-CoS Mapping T able .
3. 802.1p-CoS Mapping QoS settings allow customization of packet priority in order to facilitate delivery of data traf fic that might be affected by latency problems. The IEEE 802.1p Priority specification uses 8 priorit y levels to classify data packet s.
4. Port-COS Mapping QoS settings allow customization of VLAN ID to T raffic classifiers 1. Fill the Port List (e.g. 1-3,7) field in the port-based QoS Configuration T able. 2. Fill the mapping number in the CoS (0-7) field. 3. Click on the “OK” button to save.
6. Queue Management There are two rules for the Priorit y Queue: Weighted Round Robin ( WRR ) and Al ways Hight . T o configure Queue Rul e, select the Queue Policy drop down menu in the Queue Rule Configuration table. And Click on the “OK” button to save.
4.9 Multicast 4.9.1 IGMP Snooping Theory Computers and network devices that want to re ceive multicast transmissions ne ed to inform nearby routers that they will become mem bers of a multicast gro up. The In ternet Group Management Protocol (IGMP) is used to communicate this information.
A host sends an IGMP “report” to join a group A host will never send a report when it wants to leave a group (for version 1). A host will send a “leave” report when it wants to leave a group (for version 2). Multicast routers send IGMP queries (to the all-host s group address: 224.
4.9.2 St atic Routing Port This function is to configure ports to be the member of IGMP Group s in VLANs. T o do this, fill the Port List field and the VID field for the static routing and click on the “Add ” button to save. 4.10 Port Analysis 4.10.
4.10.2 Port Mirror Port Mirroring is a method of monitoring network traf fic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of s w itch performance and alter it if necessary .
4.1 1 Storm Control This function is to control the Braodcast S torm, Mu lticast S torm and Flooded S torm packet on each port. T o configur e the S torm Control, click on the Storm Control menu button. The web main page then sho ws the S trom Restricting function table.
