Configuration Spanning Tree Parameters RSTP Force Version Bridge Priority MES-2110 User's Guide 79 Chapter 10 Bridge Table 25 Configuration > Bridge Menu > RSTP System Config LABEL Forward Delay (sec) DESCRIPTION This is the maximum time (in seconds) the Switch will wait before changing states. This delay is required because every switch must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result. As a general rule: Note: 2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1) Max age (sec) This is the maximum time (in seconds) the Switch can wait without receiving a BPDU before attempting to reconfigure. All Switch ports (except for designated ports) should receive BPDUs at regular intervals. Any port that ages out STP information (provided in the last BPDU) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the Switch ports attached to the network. Click this to save your changes.

Table 26 Configuration > Bridge Menu > RSTP Per Port Config LABEL Port Type Priority (1~255) DESCRIPTION This is the port index number. Priority decides which port should be disabled when more than one port forms a loop in a switch. The allowed range is between 0 and 255 and the default value is 128. Cost (1~65535) Path cost is the cost of transmitting a frame on to a LAN through that port. It is recommended to assign this value according to the speed of the bridge. The slower the media, the higher the costsee Table 22 on page 75 for more information. Select On when the port is connected to an end node (a computer network card for example). Select Off when the port is connected to a bridge node. Edge P2P Select On when the port is connected to one bridge as a Point-toPoint link type. Select Off when the port is connected to multiple bridges as a Shared Medium link type. Select Auto to have the Switch automatically determine the link type. Port Status Port Role Undo Apply This shows whether the port is Forwarding or Blocking frame transmission. This shows the port behavior as a Disabled, Alternate, Backup, Root, Designated or NonStp port. Click this to save your changes.

A VLAN (Virtual Local Area Network) is a network that is not limited by the physical location of a device (such as a switch). 11. 2 Introduction to IEEE 802. 1Q Tagged VLANs A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source address field of the Ethernet frame).
