Chapter 7 S p anning T r ee STP (S panning T r ee Protocol), su bject to IEEE 802.1 D standard, is to disbra nch a ring network in the Data Link layer in a local netwo rk.
Port: Port 3 is the root port of switch B and port 5 is the root port of switch C; port 1 is the designated port of switch A and por t 4 is the designated port of swit ch B; port 6 is the blocked port of switch C. Figure 7-1 Basic STP diagram STP T imers Hello T ime: Hello T ime ranges from 1 to 10 seconds.
STP Generation In the beginning In the beginning, each switch regards itself as the root, and generates a configuration BPDU for each port on it as a root, with the root path cost being 0, the ID of the designated bridge being that of the switch, and the designated port being itself.
Tips ： In a STP with stable top ology , only the root port and designated port can forwa rd data, and the other ports are blocked. The blo cked ports only can receive BPDUs. RSTP (R apid S pann ing T ree P ro tocol ), evo lve d fr om t he 802 .1D STP standard, enable Ethernet ports to transit their states rapidl y .
Figure 7-2 Basic MSTP diagram MSTP MSTP divides a network into several MST r egions. The CST is generat ed between these MST regions, and multiple spanning trees can be generated in each MST region. Each spanning tress is called an instance. As well as STP , MSTP uses BPDUs to generate sp anning tree.
Figure 7-3 Port roles The S panning T ree module is mainly for spanning tree configuration of the switch, including four submenus: STP Config , Port Config , MSTP Instance and STP Security . 7.1 STP Config The STP Config function, for global configuration of spanning trees on the switch, can be implemented on STP Config and STP Summary pages.
Figure 7-4 STP Config The following entries are displayed on this screen: Global Config STP: Select Enable/Disable STP func tion globally on the switch. V ersion: Select the desired STP version on the switch. STP: S panning T ree Protocol. RSTP: Rapid S panning T ree Protocol.
that occur in a specific region before the BPDU is discarded. The default value is 20 hops. Note: 1. The forward delay parameter and the network diameter are correlated. A t oo small forward delay parameter may result in temporary loops. A too large forward delay may cau se a network unable to resume the normal state in time.

A CIST and its secondary root bridges are usually located in the high-bandwidth core region. Wrong configuration or malicious attacks may resu lt in configuration BPD U p ackets with higher priorities being received by the legal root bridge, which causes the cu rrent legal root bridge to lose its position and network topology jitter to occur .

7.5 Application Example for STP Function Network Requirements Switch A, B, C, D and E all support MSTP function. A is the central switch. B and C are switches in the convergence layer . D, E and F are switches in the access layer . There are 6 VLANs labeled as VLAN101-VLAN106 in the network.
Configure Switch B: Ste p Operation Description 1 Configure ports On VLAN → 802.1Q VLAN page, configure the link type of the related ports as T runk, and add t he ports to VLAN 101 and VLAN 106. The detailed instructions can be found in the section 802.
Configure Switch D: Ste p Operation Description 1 Configure ports On VLAN → 802.1Q VLAN page, configure the link type of the related ports as T runk, and add t he ports to VLAN 101 and VLAN 106. The detailed instructions can be found in the section 802.
Suggestion for Configuration Enable TC Protect functio n for all the ports of switches. Enable Root Protect function for a ll the ports of root bridges. Enable Loop Protect function for the non-edge ports. Enable BPDU Protect function or BPDU Filter func tion for the edge ports which are connected to the PC and server .
Chapter 8 Multicast Multicast Overview In the network, packet s are sent in three modes: unicast, broadcas t and multicast. In unicast, the source server sends separate copy information to each receiver . When a large numbe r of users require this information, the serv er must send many pieces of info rmation with the same content to the users.
1. Multicast IP Address: As specified by IANA (Internet Assigned Numbe rs Authority), Class D IP addresses are used as destination addresses of multic ast packets. The multicast IP addresses range from 224.0.0.0~239.255.255.255. The following table displays the range and description of several special multicast IP addresses.
IGMP Snooping In the network, the hosts apply to the near Router for joining (leaving) a multicast group by sending IGMP (Internet Group Management Protocol) me ssages. When the up-str eam device forwards down the multicast data, the switch is responsible for sending them to the host s.
The host, running IGMPv1, does not send IGMP l eave message when leaving a multicast group, as a result, the switch can not get the leave information of the host momentarily .
Figure 8-4 Basic Config The following entries are displayed on this screen: Global Config IGMP Snooping: Select Enable/Disable IGMP S nooping function globally on the Switch. Unknown Multicast: Select the operation for the swit ch to process unknown multicast, Forward or Discard.

Chapter 9 QoS QoS (Quality of Service) functi ons to provide different quality of service for various network applications and requirements and optim ize the bandwidth resource dist ribution so as to provide a network service experience of a better quality .
Figure 9-2 802.1Q frame As shown in the figure above, each 802.1Q T ag ha s a Pri field, comprising 3 bits. The 3-bit priority field is 802.1p priority in the range of 0 to 7. 802.1P priority determi nes the priority of the packets based on the Pri value.
Figure 9-4 SP-Mode 2. WRR-Mode: Weight Round Robin Mode. In this mode, packet s in all the queues are sent in order based on the weight value for each queue and every queue can be assured of a certain service time. The weight value indicates the occupied proportion of the resource.
The QoS module is mainly for traf fic control and priority configuration, including three submenus: DiffServ , Bandwidth Control and V oice VLAN . 9.1 DiffServ This switch classifies the ingr ess pack.

Chapter 12 SNMP SNMP Overvie w SNMP (Simple Network Management Protocol) has gained the most extens ive application on the UDP/IP networks. SNMP provides a managem ent frame to monitor and maintain the network devices. It is used for automatica lly managing the various network devices no matter the physical differences of the devices.
SNMP v1: SNMP v1 adopts Community Name authentic ation. The community name is used to define the relation between SNMP Management S tation and SNMP Agent. The SNMP packe ts failing to pass community name authentication are discarded. The community name can limit access to SNMP Agent from SNMP NMS, functioning as a p assword.
The User is configured in a SNMP Group can manage the switch via the client program on management station. The specif ied User Name and the Auth/Privacy Password are used for SNMP Management S tation to access the SNMP Agent, functioning as the pa ssword.
