System Overview
This chapter, which provides an overview of the Cisco Digital Building Cree Solution implementation, includes the following major topics:
System Topology
The Cisco Digital Building Cree Solution can be deployed in multiple deployment topologies, based on the customer's requirements and the time when the installation will be done.
Refer to the Cisco Digital Building Cree Design Guide for more details on different deployment topologies.
Figure 2-1 and Figure 2-2 show physical network topologies for a large scale lighting network integration with a Campus Network, where wiring closet access switches (Cisco Catalyst 3850 stack or Cisco Catalyst 4506-E) connect to a Campus Network aggregation/distribution switch (Cisco Catalyst 4500-X). In this deployment, the aggregation switch aggregates lighting wiring closet switches and provides IP addressing to light fixtures using DHCP. An aggregation switch in a Campus Network collapsed core/distribution layer connects to the data center via a firewall. The firewall allows only management traffic from the lighting network to flow to the data center.
Figure 2-1and Figure 2-2 show the Cisco Catalyst 3850 switch as an example data center switch for the server farm network access. However, any data center switch as recommended or implemented in the campus data center design, can be leveraged to configure network access to servers.
Note The Campus Network topology shown in Figure 2-1 is one of the deployment models of Campus Network architectures (that is, using a Collapsed Core Network topology) considered for the system design and validation. The detailed implementation of a Campus Network for enterprise network services is beyond the scope of this document. For detailed implementation and best practices for deploying the Campus Network, refer to the Cisco Campus Network CVD at the following URL:

System Networking
The Digital Building system should deploy on a separate logical network (VLAN) with a limit of 1,000 lights fixtures per VLAN. A new VLAN is required to deploy more than 1,000 light fixtures, which will restrict the number of broadcast messages the light fixtures can process at a time. Each VLAN requires a SmartCast Manager to configure, calibrate and monitor the light fixtures.
This section summarizes the logical network (VLAN) configuration for the Cisco Digital Building Cree Solution network. In Table 2-4 , which lists example implemented VLANs, the subnet mask 255.255.252.0 is used to allow up to 1000 light fixtures per VLAN, as recommended in the Cisco Digital Building Cree Design Guide, Section 4.2.
