53. 53 © 2004, Cisco Systems, Inc. All rights reserved. Distribution Layer In a switched network, the distribution layer includes several functions such as the following: Aggregation of the wiring-closet connections Broadcast/multicast domain definition VLAN routing Any media transitions that need to occur Security
