Page 6: Introduction
The Switch User’s Guide Introduction The Switch is equipped with 24 10/100BASE-TX Fast Ethernet ports and 4 combo 10/100/1000BASE-T/SFP (mini-GBIC) ports for flexible copper/fiber Gigabit connection. The Switch is an effective solution for the small and medium size business connections. This all-in-one solution economically integrates Gigabit technology to remove server bottlenecks, and speed up access to the network backbone. -

The Switch User’s Guide 10Base-T Ethernet standard, designed to raise the data transmission capacity of 10Base-T from 10Mbits/sec to 100Mbits/sec. An important technology incorporated by 100Base-T is its use of the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol, which is the same protocol that 10Base-T uses, because of its ability to work with several different types of cable, including basic twisted-pair wiring. -

The Switch User’s Guide Configuration 5.1 System 5.1.1 IP Address 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 the factory-default IP Address is 192.168.2.11. You can change the factory-default Switch IP address to meet the specification of your networking address scheme. - Page 24 The Switch User’s Guide management stations (NMSs), SNMP agents, Management information base (MIB) and network-management protocol： Network management stations (NMSs)：Sometimes called consoles, these devices execute management applications that monitor and control network elements. Physically, NMSs are usually engineering workstation-caliber computers with fast CPUs, megapixel color displays, substantial memory, and abundant disk space.

Page 35: Redundancy
The Switch User’s Guide 5.3 Redundancy 5.3.1 Spanning Tree 1. Spanning Tree Protocol The IEEE 802.1D Spanning Tree Protocol allows for the blocking of links between switches that form loops within the network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. - Page 36 The Switch User’s Guide One switch is elected as the root switch The shortest distance to the root switch is calculated for each switch A designated switch is selected. This is the switch closest to the root switch through which packets will be forwarded to the root. A port for each switch is selected.
- Page 37 The Switch User’s Guide Switch boot Blocking Listening Disabled Learning Forwarding Figure 5-20 STP Port State Transitions You can modify each port state by using management software. When you enable STP, every port on every switch in the network goes through the blocking state and then transitions through the states of listening and learning at power up.

Forward Delay Timer The amount time spent by a port 15 seconds in the learning and listening states waiting for a BPDU that may return the port to the blocking state.
- Page 39 The Switch User’s Guide NOTICE: The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error will occur. Max. Age – The Max Age can be from 6 to 40 seconds. At the end of the Max Age, if a BPDU has still not been received from the Root Bridge, your Switch will start sending its own BPDU to all other Switches for permission to become the Root Bridge.
- Page 40 The Switch User’s Guide Figure 5-21 before Applying the STA Rules In this example, only the default STP values are used. Figure 5-21 After Applying the STA Rules The switch with the lowest Bridge ID (switch C) was elected the root bridge, and the ports were selected to give a high port cost between switches B and C.

Lower numbers will be used as forwarding ports first. The range is from 0 to 65535. The default values based on IEEE802.1D are: 10Mb/s = 50-600, 100Mb/s = 10-60, 1000Mb/s = 3-10 Figure 5-24 5.3.3 Link Aggregation... -

The tagging feature allows VLAN to span multiple 802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled on all ports and work normally. Some relevant terms: Tagging - The act of putting 802.1Q VLAN information into the header of a packet.
- Page 47 The Switch User’s Guide Figure 5-27 Port VLAN ID Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact.

- Page 48 The Switch User’s Guide VLANs and Trunk Groups In order to use VLAN segmentation in conjunction with port trunk groups, you can first set the port trunk group(s), and then you may configure VLAN settings. If you wish to change the port trunk grouping with VLAN already in place, you will not need to reconfigure the VLAN settings after changing the port trunk group settings.

The Switch User’s Guide Figure 5-57 5.6 Multicast 5.6.1 IGMP Snooping Theory Computers and network devices that want to receive multicast transmissions need to inform nearby routers that they will become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to communicate this information. - Page 69 The Switch User’s Guide 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-hosts group address: 224.0.0.1) periodically to see whether any group members exist on their sub networks.
