Page 31: Link Aggregation Characteristics
24-Port Managed Gigabit Switch TEG3224T treats all ports in a trunk group as single port. Data transmitted to a specific host will always be transmitted over the same port in a trunk group. This allows packets in a data stream to arrive in the same order they were sent.
Page 32: Link Aggregation Requirement For Port Settings
24-Port Managed Gigabit Switch physical path. This allows traffic loads to be distributed across multiple communication links, and a link failure within the group causes the network traffic to be directed to the remaining links in the group. The Spanning Tree Protocol will treat a port trunking group as a single link, on the Switch level.

Page 38 24-Port Managed Gigabit Switch chosen as the root switch. All the other switches in the layer-2 topology expect to see BPDUs the root switch within the maximum age time, which defaults to 20 seconds. If the switches do not see a BPDU message from the root within this period, they assume that the root switch has failed and will begin a new election process to choose a new root switch.
Page 39 24-Port Managed Gigabit Switch  With the lowest segment accumulated path cost to the root bridge.  With the lowest switch ID  With the lowest priority  With the physically lowest-numbered port on the switch After going through these steps for each segment, each segment will have a signal designated port that it will use to reach the root switch.
Page 40 24-Port Managed Gigabit Switch 6. 802.1w Rapid Spanning Tree The Rapid Spanning Tree Protocol (RSTP) is an IEEE standard, 802.1w, that is interoperable with 802.1d and an extension to it. With RSTP, there are only three port states: discarding, learning and forwarding.
Page 41 24-Port Managed Gigabit Switch 7. Edge Port The edge port is a designation used for a port that is directly connected to end stations where bridging loops cannot be created in the network. Therefore, the edge port directly transitions to the forwarding state, and skips the listening and learning stages.

Page 51: Igmp Snooping
24-Port Managed Gigabit Switch 3.8 IGMP Snooping 3.8.1 IGMP Snooping Introduction IGMP Snooping is the process of listening to IGMP traffic, which allows the switch to "listen in" on the IGMP conversation between hosts and routers by processing the layer 3 IGMP packets sent in a multicast network.
Page 52: Igmp Snooping Working Mechanism
24-Port Managed Gigabit Switch 3.8.2 IGMP Snooping Working Mechanism When IGMP snooping is enabled, the multicast router sends out periodic IGMP general queries to all VLANs. The switch responds to the router queriers with only one join request per MAC multicast group, and the switch creates one entry per VLAN in the Layer 2 forwarding table for each MAC group from which it receives an IGMP join request.
Page 53 24-Port Managed Gigabit Switch ther router continues forwarding the multicast traffic to the VLAN. The switch only forwards IP multicast group traffic to those hosts listed in the forwarding table for that IP multicast group. When hosts need to leave a multicast group, they can either ignore the periodic general-query requests sent by the router, or they can send a leave message.

Page 151: Glossary
24-Port Managed Gigabit Switch 7.2 Glossary ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID. There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE also contains many detailed, different parameter options that are available for individual application.
Page 152 24-Port Managed Gigabit Switch beyond the limits of a port and to increase the redundancy for higher availability. (Also Port Aggregation, Link Aggregation). ARP is an acronym for Address Resolution Protocol. It is a protocol that used to convert an IP address into a physical address, such as an Ethernet address.
Page 153 24-Port Managed Gigabit Switch first client's assignment is valid (its lease has not expired). Therefore, IP address pool management is done by the server and not by a human network administrator. Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task.

The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a different host name, provides the session and transport services described in the Open Systems Interconnection (OSI) model.
Page 161 24-Port Managed Gigabit Switch Policer A policer can limit the bandwidth of received frames. It is located in front of the ingress queue. POP3 POP3 is an acronym for Post Office Protocol version 3. It is a protocol for email clients to retrieve email messages from a mail server.
Page 162 24-Port Managed Gigabit Switch There are six QCE frame types: Ethernet Type, VLAN, UDP/TCP Port, DSCP, TOS, and Tag Priority. Frames can be classified by one of 4 different QoS classes: "Low", "Normal", "Medium", and "High" for individual application. QCL is an acronym for QoS Control List. It is the list table of QCEs, containing QoS control entries that classify to a specific QoS class on specific traffic objects.
Page 163 24-Port Managed Gigabit Switch It is a protocol that is used to obtain an IP address for a given hardware address, such as an Ethernet address. RARP is the complement of ARP. Router Port A router port is a port on the Ethernet switch that leads switch towards the Layer 3 multicast device.

TELNET enables the client to control the server and communicate with other servers on the network. To start a Telnet session, the client user must log in to a server by entering a valid username and password.
Page 167 24-Port Managed Gigabit Switch (TCP) that uses the Internet Protocol (IP). Unlike TCP, UDP does not provide the service of dividing a message into packet datagrams, and UDP doesn't provide reassembling and sequencing of the packets. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order.
