47. TP Requirements Before STP can configure the network the system must satisfy the following requirements e Communication must be established between all bridges This communication is carried out using Bridge Protocol Data Units BPDUs which are transmitted in packets with a known multicast address 3 35 PT 7728 Users Manual Featured Functions e Each bridge must have a Bridge Identifier that specifies which bridge acts as the central reference point or Root Bridge for the STP system Bridges with a lower Bridge Identifier are more likely to be designated as the Root Bridge The Bridge Identifier is calculated using the MAC address of the bridge and a priority defined for the bridge The default priority of PT 7728 is 32768 e Each port has a cost that specifies the efficiency of each link The efficiency cost is usually determined by the bandwidth of the link with less efficient links assigned a higher cost The following table shows the default port costs for a switch Port Speed Path Cost 802 1D Path Cost 1998 Edition 802 1w 2001 10 Mbps 100 2 000 000 100 Mbps 19 200 000 1000 Mbps 4 20 000 STP Calculation The first step of the STP process is to perform calculations During this stage each bridge on the network transmits BPDUs The following items will then be calculated e The bridge that will act as the Root Bridge The Root Bridge is the central reference point from which the network is configure
48. U after a certain interval the Max Age time the bridge assumes that the Root Bridge or a link between itself and the Root Bridge has gone down This will trigger the bridge to reconfigure the network to account for the change If you have configured an SNMP trap destination the first bridge to detect a topology change in your network sends out an SNMP trap Differences between RSTP and STP RSTP is similar to STP but includes additional information in the BPDUs that allow each bridge to confirm that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge Adjacent bridges connected via point to point links will be able to enable 3 36 PT 7728 Users Manual Featured Functions a link without waiting to ensure that all other bridges in the network have had time to react to the change The main benefit of RSTP is that the configuration decision is made locally rather than network wide allowing RSTP can carry out automatic configuration and restore a link faster than STP STP Example The LAN shown below has three segments with adjacent segments connected using two possible links The various STP factors such as Cost Root Port Designated Bridge Port and Blocked Port are shown in the figure LAN Segment 1 Port 1 Port 1 Port 1 Designated Root Port Root Port Bridge Port Cost 100 Bridge B Port 2 Designated Bridge Port Bridge X Port 2
49. Using VLANS also provides you with three other benefits e VLANS ease the relocation of devices on networks With traditional networks network administrators spend much of their time dealing with moves and changes If users move to a different subnetwork the addresses of each host must be updated manually With a VLAN setup if a host on VLAN Marketing for example is moved to a port in another part of the network and retains its original subnet membership you only need to specify that the new port is on VLAN Marketing You do not need to carry out any re cabling e VLANs provide extra security Devices within each VLAN can only communicate with other devices on the same VLAN If a device on VLAN Marketing nePT to communicate with devices on VLAN Finance the traffic must pass through a routing device or Layer 3 switch e VLANs help control traffic With traditional networks congestion can be caused by broadcast traffic that is directed to all network devices regardless of whether or not they need it VLANs increase the efficiency of your network because each VLAN can be set up to contain only those devices that need to communicate with each other VLANs and the PowerTrans Your PT 7728 provides support for VLANs using IEEE Std 802 1Q 1998 This standard allows traffic from multiple VLANs to be carried across one physical link The IEEE Std 802 1Q 1998 standard allows each port on your PT 7728 to be placed as follows e Ina single VLAN defin
