500.book Page 65 Thursday, September 2, 1999 1:17 PM 4 In this chapter Advanced Configuration In this chapter you will learn how to use Advanced Configuration effectively. This chapter covers the Virtual LAN (VLAN) features. You can create logical network groups (VLANs) by segmenting the switch; for example, according to the subnetting scheme within your network. Each VLAN is an isolated group and the switch only forwards traffic between members of the same group.
500.book Page 66 Thursday, September 2, 1999 1:17 PM C H A P T E R 4 Advanced Configuration • Allocate network resources (such as servers) to groups For a more comprehensive explanation of the VLAN concept, refer to the online help. Warning when using STP It is important to be aware of problems that may arise when using Spanning Tree and VLANs. The Spanning Tree can use alternative paths (such as different ports) to get messages to their destination.
