System Components

The components validated within this system consist of a mix of Cisco products (Table 1) and Signify products (Table 2).

Table 3 provides the list of third party infrastructure components used in the system.

IP Addressing

This section summarizes the VLAN and IPv4 DHCP address pools in the system.

VLANs

Table 4 shows the Layer 2 and Layer 3 VLAN IP addressing of the system.

Note: The VLANs and subnet mask shown in Table 4 are only examples that are used in the standalone Cisco Smart+Connected Solutions with Signify Interact Office Wired system deployment validation. VLAN numbering and mask may vary based on your actual deployment; follow best practices as recommended by enterprise IT network engineers.

Dynamic Host Configuration Protocol

Dynamic Host Configuration Protocol (DHCP) for the Signify luminaires IPv6 addressing is not needed since Signify uses Stateless Address Auto Configuration (SLAAC). In SLAAC, a router periodically advertises an IPv6 address prefix. Signify luminaires and Envision Gateway will get the IPv6 address that is built based on that prefix and device MAC address.

The IPv4 DHCP pools are created, as shown in Table 5, on the C3650 for management and wireless clients to enable PCA access to Signify Envision Manager Web.

Note: The DHCP pools and IP range shown in Table 5 are example pools used in the system for validation. Signify Personal Control Application (PCA) will be leveraging corporate IT wireless network. Follow the DHCP pool and IP range creation for appropriate VLANs during the deployment based on Enterprise IT network deployment when integrating a lighting network to an enterprise IT network.

Lighting Aggregation Switch

VLAN numbering, IP addressing, and other configurations used in this chapter are the example configurations, as shown in the lighting network topology in Figure 3. However, the VLAN numbering and IP addressing scheme may vary based on network planning in your deployment.

The Catalyst 3650 switch is the lighting network aggregation switch providing IPv6 lighting network router prefix and network Layer 3 routing functionalities for the lighting network. The following sections cover the implementation of Layer 2, Layer 3, and security features as required on the C3650 switch.

Layer 2 and Layer 3 Configuration

This section defines the implementation of VLANs and Layer 3 logical interfaces on the C3650 switch.

1. Configure VLANs, which must be created along with ports assignment on the 3650 switch:

2. Create Layer 3 switched virtual interface (SVI) for the VLANs 50, 80, 90, 101, and 102. The configuration below shows SVIs for the VLAN on the C3650 switch:

3. Enable IPv6 unicast routing features on the 3650 switch using the following command:

Note: Steps 2 and 3 above enable IPv6 routing and router IPv6 prefix advertisements for the IPv6 SLAAC address assignment to Signify Envision gateways and luminaires in a VLAN.

4. Create port channel interfaces on the 3650 to 2960X, the UCS Server, and the Cisco Adaptive Security Appliance (ASA) firewall in the network as shown below:

5. Enable EtherChannel on the appropriate physical switch ports connected to the 2960X, UCS server, and ASA. The following configuration shows the port channel assignment to switch physical ports:

Physical Links to 2960X Switch

Physical Links to UCS Server

Physical Links to ASA5585 Firewall Switch

6. Add IPv4 and IPv6 traffic static routes to the ASA with the VLAN80 default gateway as the VLAN80 bridges the lighting and IT network traffic between the ASA and the 3650. The following commands add static routes to the Data Center IPv4 and IPv6 destination networks on the 3650 switch:

7. Enable rapid per-vlan spanning tree:

Security

This section defines the implementation of security features on the C3650 switch.

Disabling Telnet

Since Telnet is not secure, it should be disabled for accessing the device. The following commands disable Telnet and enable only Secure Shell (SSH) access to the 3650 switch.

SNMP Monitoring

Simple Network Management Protocol (SNMP) facilitates the exchange of management information among network devices. System administrators can remotely manage network performance, find and solve network problems, and plan for network growth by using SNMP. The SNMP agent gathers data from the MIB, which is the repository for information about device parameters and network data. The SNMP agent also can send traps (notifications) of certain events, to the SNMP manager.

SNMP v3 is used for monitoring the switches in the lighting network via traps upon switch ports status change and security violations. Enable and configure the SNMP v3 traps on switch to track ports up/down and security violations, as shown below:

For example:

Note: The IP address of the network management station (NMS) host is the IP address of the network management tool supporting SNMP v3 that is being used for monitoring the system.

Wiring Closet Access Switch (C2960X)

This section covers wiring closet access switch C2960X Layer 2, Layer 3 networking, and security configurations.

For Star Topology

Layer 2 and Layer 3 Configuration

This section defines the implementation of VLANs and Layer 3 logical interfaces on the C2960X switch.

8. Enable rapid per-vlan spanning tree.

Security

This section defines the implementation for disabling Telnet and enabling SNMP features on the C3650.

Disabling Telnet

Since Telnet is not secure, it should be disabled for accessing the device. The following commands disable Telnet and only enable SSH access to the 3650 switch.

SNMP Monitoring

SNMP facilitates the exchange of management information among the network devices. The system administrator can remotely manage the network performance, find and solve network problems, and plan for network growth by using the SNMP. The SNMP agent gathers data from the MIB, which is the repository for information about device parameter and network data. The SNMP agent also sends traps (notifications) of certain events, to the SNMP Manager.

SNMP v3 is used for monitoring the switches in the Lighting network via traps on switch port status change and security violations. Enable and configure SNMP traps on the port to monitor port change status and violations on the device.

For example:

Note: The IP address of the NMS host is the address of the network management tool supporting SNMP v3 that is being used for monitoring the system.

Access Lists

Configure and apply the following access-list on the interfaces connecting to the Envision Gateway:

Note: FF12::/16 range is the ipv6 multicast address used by the Signify Envision Gateway for spur connection.

Spanning Tree Security

Enable spanning tree BPDU Guard and PortFast on all interfaces connecting to the Envision Gateways.

For Ring Network Topology

Note: This section is optional and required only when the REP ring network topology is implemented in the deployment solutions.

5. Configure interfaces on the CDB-8U connected to the Signify luminaires, as shown below in VLAN 101 or 102:

The switch CLI command power inline port POE-HA enables Perpetual PoE and Fast PoE features on switch ports. The command power inline port 2-event enables 2-event classification on switch ports for Signify luminaires, to provide power up to 30W.

6. Enable rapid per-vlan spanning tree.

Note: The following steps to enable MAC Authentication Bypass (MAB) are valid only if Cisco ISE is used for MAB-based device authentication MUD_URI visibility in the Cisco Identity Services Engine (ISE). The following steps can be ignored if you do not use ISE in your deployment. However, it is recommended to use ISE for device authentication and profiling for enhanced system network security.

7. Enable Policy Map for MAB:

8. Enable MAB in interfaces where PoELC lights are connected:

Note: It is recommended to enable MAB in switch ports for luminaires and network security. However, it can be disabled by using "no mab" under the interface configuration.

Note: By default, all the configuration required for Fast PoE, access session, and 2-event classifications are enabled in CDB.

Security

The following sections cover security configurations on the CDB switch for Signify luminaires.

Disabling Telnet

Since it is not secure, Telnet should be disabled for accessing the device:

Note: All the above configurations are required in all the CDB switches participating in the REP ring topology.

Firewall (Cisco ASA 5585)

In the Cisco Smart+Connected Solutions with Signify Interact Office Wired solution, ASA acts as a firewall and protects the applications in the data center. Traffic coming into the data center from the network, along with traffic from lighting network, should pass through the ASA firewall.

The ASA is configured to operate as follows:

■Firewall Mode: Routed

■Context: Multiple

Several tasks are required to complete ASA configuration. The work flow is shown in Figure 5.

Figure 5 ASA Configuration Flow

Creating Contexts

Two firewall contexts are created to separate the Lighting Network traffic from the Data Network traffic:

1. Enable mode multi-context on the ASA firewall:

2. Create a new ASA context for the Lighting Network traffic:

Port Channel to Network

1. ASA is configured with a port channel having two member links to C3650 switch. The port channel includes the two 1 Gig interfaces available on the ASA 5585X. It is configured from the system context and no name or security-level is assigned.

2. VLAN subinterfaces provide access to different components in the network, such as the data center, management network, and Envision Manager Server. Subinterfaces based on VLANs are configured on the port channel from the system context.

The VLAN and subinterface configuration for server network access:

VLAN and subinterface configuration for data center access on the firewall:

VLAN and subinterface configuration for data network access on the firewall:

VLAN and subinterface configuration for the lighting network on the firewall:

Allocating Interfaces to Firewall Contexts

The port channel subinterfaces created in the previous section are assigned to the firewall contexts, as shown below. This segregates the lighting network traffic from the data network traffic into different security contexts on the firewall.

Interface Configuration

Within each of the security contexts, the interfaces are configured with names, security levels, and IP addresses. Table 6 summarizes the interface configuration used along with the zones each interface is part of in the contexts.

The firewall security level can be configured between 0 and 100; 0 is the least secure zone and 100 is the most secure zone. See Table 7.

Note: On port channel 10.80 in ASA, we enable router advertisement suppression.

Static Routes

The following static routes are configured on the ASA contexts:

Light Management Context

Admin Context

Access Control Lists and Access Control List Entries

By default, ASA denies all traffic moving from a lower security level to a higher security level. Access control lists (ACLs) are configured to enable required traffic between interfaces. The access list entries (ACEs) follow.

ACE to allow traffic from the Envision Gateway to the Envision Manager in Lighting Management context:

Apply the access-list on the lighting network interface:

ISE enabling HTTP and HTTPS access to Envision Manager in admin context:

ACE allowing management network reachability to ISE in the Data Center through admin context:

Apply the access-list on the data network interface:

VM Installation (ISE, Signify Envision Manager Web)

The following sections describe procedures involved in deploying the virtual machines for ACS and a Window Server 2012 server for AD/DNS services.

Configuring Network Device Authentication (ISE) (Optional)

This section covers how to deploy Cisco ISE 2.0 on the UCS server platform in the data center for network devices authentication (RADIUS) and security.

Installation of Cisco Identity Services Engine

The prerequisites and the necessary information to install ISE can be found at the following URL:

■ https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/install_guide/b_ise_InstallationGuide24/b_ise_InstallationGuide24_chapter_00.html

This document describes different deployment scenarios with ISE. One should choose deployment scenario according to the use case needs.

Configuring Cisco Identity Services Engine

ISE 2.0 is used for providing device authentication and authorization in the network via RADIUS. ISE is deployed in a VM and assigned an IP address in the VLAN 70 residing behind the firewall. The firewall ports need to be opened for RADIUS communication from the VLAN 90 to ISE.

Figure 7 AAA Configuration Flow

Note: The deployment of ISE in the solution is optional for the MUD-URI feature. However, it is recommended to use ISE for devices authentication and enhanced network security.

The following configurations are required to implement MUD-URI visibility in ISE.

Switch AAA Configuration

Perform the following steps on each switch in the network (for example, Cisco Catalyst 3650 and Cisco CDB and Cisco Catalyst 3650 switches in the deployment, as shown in Figure 3) to configure AAA.

1. On the switches, configure ISE as the RADIUS server:

ISE is the name of the RADIUS defined. Any user-defined name can be used. The RADIUS server "ISE" defined is added to the AAA group-server.

2. Create a local user with full privilege for fall back with the username command as shown here:

3. Configure login authentication and exec and console authorization using the following commands, which show the different authentication groups that could be created.

4. Use the Telnet Console method on Virtual Teletype (VTY) authentication and authorization:

With this step, the different authentication groups that have been created should be attached to the respective login type.

ISE Configuration

Perform the following steps on the ISE server for enabling RADIUS-based device authentication and authorization:

1. Log in to ISE. Figure 8 shows ISE summary after successful login.

Figure 8 ISE Login Success Page

2. Add the 3850 standalone switch or the stack as a network device to ISE. To add Network Device, select Network Devices from Administration > Network Resources, as shown in Figure 9.

Figure 9 Select Network Devices in ISE

3. On selecting Network Devices, the page should display devices (if any) that were added, as shown in Figure 10.

Figure 10 Network Devices in ISE

4. To add network device to the list, click Add, enter the device name and the correct IP address. The IP address of the network device should be reachable from ISE. See Figure 11.

Figure 11 Adding a Network Device in ISE

5. After adding a network device, select the RADIUS authentication settings and then enter the pre-shared key that is common to the network device, as shown in Figure 12. This pre-shared key should be same as the key added in the AAA configuration of the network device.

Figure 12 RADIUS Authentication Settings

6. To create an identity (user), go to Administration > Identity Management > Identities > Users. Add the Name and the login password, as shown in Figure 13 and Figure 14. These credentials will be used to log in to the network device from ISE.

Figure 13 Adding a User Identity in Identity Management

Figure 14 Creating a New User in Identity Management

This completes the ISE RADIUS configuration for network devices authentication and authorization.

7. After performing the above steps, the endpoints can be seen at Context Visibility > Endpoints (Figure 15).
