Using Converged Access Workflow
Converged Access Workflow Overview
The Converged Access workflow simplifies, automates and optimizes deployment of various enterprise-class next generation wireless deployment models for campus and branch networks.
Cisco Prime Infrastructure can automate the converged access deployment of wireless networks using converged access components such as Catalyst 3650, 3850, 4500 SUP 8-E switches, and Cisco 5760 Wireless LAN controller (WLC). The catalyst switches can be deployed as Mobility Agent (MA), Mobility Controller (MC), and Guest Anchor controller (GA).
Figure 38-1 illustrates the wireless converged access deployment models.
Figure 38-1 Converged Access Workflow Overview
Single-Switch Small Network Deployment Model
This deployment model assumes single Catalyst 3650, 3850 or 4500 SUP 8-E switch deployed in Access layer in combined MA and MC roles. The Catalyst switches can be deployed in individual standalone system mode or in stackwise redundant supervisor mode.
Controller-Less Single/Multi-Domain Deployment Model
This deployment model consists of multiple sub-domains and allows inter-domain MC peering for end-to-end seamless roaming across sub-domains. The MA switches are deployed in Access layer while the MC switches can be placed in Distribution layer.
Controller-Based Single/Multi-Domain Deployment Model
A large scale converged access campus building is deployed with external 5760 WLC as MC. The Access layer switches are deployed as MA across multiple buildings with centralized 5760 MC. In such large network, multiple 5760 WLCs may co-exist for better load balancing and redundancy. Depending on the roaming requirement across different buildings, the inter-domain mobility peering between 5760 WLCs can be established.
Centralized Wireless Campus Deployment Model
In this deployment model, the switches in Access layer remain in traditional switching mode and wireless communication between Access Point (AP) and WLC is built as overlay network. In large scale campus deployments, multiple 5760 WLCs can be deployed for better load balancing and redundancy. To provide seamless large mobility domains, the inter-domain mobility peering 5760 WLCs can be established.
- Simple Automated Deployment—Simplifies the converged access deployment by automating the device configuration process. Requires only a few deployment specific inputs from the network administrator and pushes the complete converged access configurations to the network devices.
- Error Free Deployment—The template-based configuration used by Cisco Prime Infrastructure avoids manual misconfigurations, making it easier to build/maintain enterprise-wide standardized configurations that are well understood by the network administrator.
- Optimized Deployment—The configuration templates used by Cisco Prime Infrastructure incorporates a large number of Cisco best practice guidelines, improving the deployment quality. Some of the best practice wireless technologies/features that are automatically included in the template are Band-Select, Radio Resource Management (RRM), Fast SSID-Change, CleanAir, and Wireless QoS.
- High Scalability—Supports large enterprises with thousands of branches. It not only reduces efforts to deploy greenfield branches, but also simplifies large scale conversion of traditional Ethernet based branch networks to converged access branches in an error-free way.

Table 38-5 describes the Layer 2 and Layer 3 prerequisites, and sample configuration for GA. In the sample configuration, the following nomenclature is used to represent the wireless management VLAN and Guest VLAN details for GA:
- WM_VLAN - Name of the Wireless Management VLAN
- WM_VLAN_id - ID of the Wireless Management VLAN
- GUEST_VLAN_Name - VLAN name of Guest Anchor Controller
- GUEST_VLAN_id - VLAN ID of Guest Anchor Controller
Table 38-5 Layer 2 and Layer 3 Prerequisites for Guest Anchor Controller
Prerequisites for Server Configuration
– All network-wide catalyst switches and 5760 WLCs must be configured with SNMP.
– The Converged Access switches must be added to the inventory of Cisco Prime Infrastructure. You need to provide SNMP and Telnet credentials to add the devices to the inventory.
– Link Cisco Prime Infrastructure with Cisco ISE engine as external server to centrally monitor end-to-end client connectivity and policy enforcement details.
– All network devices including catalyst switches and Guest Anchor WLC must be configured in Cisco ISE/ACS to enable centralized policy engine function.
– AAA configuration is not required for converged access on individual network devices as it is automatically generated by Converged Access Workflow.
Converged Access Template-Based Deployment
Cisco Prime Infrastructure uses different templates for different deployment models. You need to select the appropriate template-based on your network topology as explained in Table 38-6 :

Entering Configuration Values for Controller-Less Single-Switch Deployment Model
A small-sized remote branch office or retail store may consists of a single converged access switch (standalone or stack) to provide network connectivity to the wired and wireless users.
For such network designs, the switch integrates both MC and MA functions. These networks may need guest wireless services, as well as common security and network access policy enforcement across all deployed sites.
The network administrator can use Cisco Prime Infrastructure IOS-XE Controller Small Network template to deploy converged access. Figure 38-2 illustrates the reference network for single-switch small network that shows three branch offices. Each site can be independently deployed using the workflow. Alternatively, one deployment workflow can deploy multiple sites. Prime Infrastructure allows you to configure the devices in five WLANs. Figure 38-2 illustrates three WLAN configuration scenario in the single-switch small network topology.
