Setting up Virtual Local Area Networks (VLANs) on the Summit eases many
This chapter describes the concept of VLANs and explains how to implement VLANs on the Summit.
OVERVIEW OF VIRTUAL LANS
The term VLAN is used to refer to a collection of devices that communicate as if they were on the same physical LAN. Any set of ports (including all ports on the switch) is considered a VLAN. LAN segments are not restricted by the hardware that physically connects them. The segments are defined by flexible user groups you create with the
BENEFITS
Implementing VLANs on your networks has the following advantages:
•VLANs help to control traffic.
