Updated: April 10, 2026

Want to summarize with AI?

Describes how to verify Local Area Bonjour in multicast DNS mode for both LAN and wireless networks to ensure proper service discovery functionality.

This section shows how to verify Local Area Bonjour in Multicast DNS mode for LAN and Wireless networks.

Verify SDG-agent status

Use the sample outputs to verify SDG-agent status and understand the command output format for various mDNS service discovery commands.

This is a sample output of the show mdns-sd service-listservice-list-name {in | out} command.


Name           Direction  Service    Message-Type     Source
============================================================
VLAN100-list    In         Printer   Announcement      -
                In         Airplay   Query             -
                In         CUSTOM1   Any               -
VLAN300-list    Out        Printer   Announcement     Vl200

This is a sample output of the show mdns-sd service-definitionservice-definition-nameservice-type {custom | built-in} command.


Service                PTR                        Type
=========================================================================
apple-tv               _airplay._tcp.local         Built-In

CUSTOM2               _customA._tcp.local         Custom
                      _customA._tcp.local

This is a sample output of the show mdns-sdservice-policy-nameinterfaceinterface-name command.


Name			Service-List-In			Service-List-Out	
==================================================
mdns-policy-1		VLAN100-list			VLAN300-list		
mdns-policy-2		VLAN400-list			VLAN400-list

This is a sample output of the show mdns-sd summary command.

Verify wide area Bonjour controller status

Verify wide area Bonjour controller status using show commands to display controller summary, export summary, statistics, and detailed information.

This is a sample output of the show mdns controller summary command.

Device# show mdns controller summary

Verify mDNS cache configurations

This reference helps you verify mDNS cache configurations using show commands that display cache information from both Active and Standby devices.

These show commands display cache from both Active and Standby devices using the chassis option:
