Configuration Example for FlexConnect Mode - Wireless and Wired

Overview

This chapter provides configuration guidelines to implement Local Area Bonjour enabling end-to-end policy-based mDNS service discovery and distribution across multilayer wired and wireless FlexConnect local-switching mode. The first hop mDNS gateway at Layer 2 access switch must be implemented in service peer mode and paired with common distribution-layer switch in SDG agent role IP gateway function to wired and wireless clients. The network-wide distributed SDG agent can be paired alternatively with the Cisco Catalyst Center to enable mDNS service-routing across IP core network providing mDNS service assurance, monitoring and troubleshooting.

The following figure illustrates unicast mode bonjour network environment with AirPrint capable printer and wireless user computer (macOS, Microsoft Windows, and so on.) connected to the same Ethernet switch. The network administrator implements the policy permitting additional endpoints associated to nearby location Ethernet switch to discover and use remote AirPrint capable Printer without flooding mDNS over wired and wireless networks.

Verifying Cisco Catalyst Center Configuration and Service Routing Status

The Cisco Wide Area Bonjour application supports comprehensive assurance capabilities to manage service routing with network-wide distributed Cisco Catalyst switches in SDG Agent role and mDNS services discovered over Wide Area Bonjour domain. The assurance capabilities in Cisco Wide Area Bonjour provides the ability to determine service routing state, mDNS service state, and many more information at various levels for day-2 operations, analysis and troubleshooting. Each category serves unique function to manage and troubleshoot Wide Area Bonjour service routing for day-2 operation.

This sub-section provides brief overview for each category of monitor function:

  • Dashboard: The landing page of Cisco Wide Area Bonjour application provides key statistics in various formats to quickly determine service routing health across the network. The network administrator can monitor operational status of service routing with SDG Agent devices, historical chart of service discovery request, processing and drops from network-wide distributed devices and top five talkers across the network.

  • Sub-Domain 360°: The network administrator can briefly collect statistics and status counts in 360° view. The left-panel monitoring, and configuration bar is automatically open upon clicking selected sub-domain to verify configured policies, discovered service-instances on per sub-domain basis of the configuration section.

  • Monitor: A comprehensive 3-tier monitoring and troubleshooting function of Cisco Wide Area Bonjour application for various day-2 operations. The detail view of SDG Agent, Service-Instance, and advanced Troubleshooting capabilities allows network administrator to manage and troubleshoot Wide Area Bonjour domain with a single pane of glass on Cisco Catalyst Center.

For more information, see Cisco Wide Area Bonjour on Cisco Catalyst Center User Guide, Release 2.1.2 guide. The assurance capabilities and operation details are explained in Monitor the Cisco Wide Area Bonjour Application chapter to manage Cisco Wide Area Bonjour application with various supporting service routing assurance function.
