Core
Stacked or single HA coreswitch design reducedconfiguration by > 80%
No first hop routing protocolrequired (HSRP, VRRP, etc.)
All links in the network are activeand passing traffic
No layer 2 loops means noSpanning Tree Protocol (STP) to
tune or troubleshoot Uplink or core switch failure
recovery is very fast, < 1 secondwith no tuning

Access and Server Room
Same VLAN for wired data,wireless data, wired voice, andwireless voice in each closet
Simplified IP configuration
All access switch configurationsidentical except for managementaddress
Access ports have a single template
Uplinks all member of EtherChannel
Double bandwidth of traditionaldesign from access to core, bothuplinks are active
Easily scale bandwidth by addinglinks to the EtherChannel
