Whether the distribution layer role in your network design is serving as purely LAN access aggregation, a

collapsed core, or network-services aggregation, the distribution layer configuration provides the processes and

procedures to prepare this layer of the LAN for your application.

Distribution Layer Platforms

You can use multiple platforms to deploy the simplified distribution layer design. Physically, the distribution layer

can be a Cisco Catalyst 6500 Virtual Switching System (VSS), a Cisco Catalyst 4500-X VSS, a highly available

Cisco Catalyst 4507R+E switch pair in VSS mode, or a stack of Cisco Catalyst 3750-X switches. It is important to

note that although each switch has different physical characteristics, each appears to the rest of the network as

a single node and provides a fully resilient design.
