37 Chapter 6 Switching C oncepts The following sections provide brief explanations of some of the concepts related to switching. If more information is required, please refer to networking textbooks, online resources (i.e. www.oreillynet. com ) or your MIS manager.
38 Forward Delay After a recalculation of the spanning tree, the Forward Delay parameter regulates the delay before each port b egins transmitting traffic. If a port begins forwarding traffic too soon (before a new root bridge has been selected), the network can be adversely affected.
39 6.2.2 Flow Control With a link operating at a high data rate, a switch may experience occasional limitations in the buffe r space used to store Ethernet frames before forwarding them. In this situation, if the sending station continues to send frames, the switch will have no option but to discard the frames.
40 Appendix A: Troubleshooting In the unlikely event your network does not operate properly, follow the troubleshooting tips below: CHECK YOUR POWER CONNECTION. Is the Power LED on? If not plug the p ower cord into another known working AC outlet. CHECK YOUR NETWORK CABLE.
41 Appendix B: VLAN Description and Examples Packets received by the sw itch will be treated in the following way with regard to the Switch’s VLAN settings: 1. When an untagged packet enters a port, it will be automatically tagged with the port’s default VLAN ID tag number.
42 3. To allow untagged packets to participate in the ‘New’ VLAN, make sure to change the Port VLAN IDs for the relevant ports. To access the Port VLAN ID page choose c . PVID Settings from the VLAN Setup menu. Use the space bar to add an ‘X’ i ndicating which PVID is assigned to which port.
