Environment This articles applies to Aruba Mobility Controllers running ArubaOS 6.3.0.0 or higher

 

 

Network administrators are faced with a difficult choice between propagating mDNS traffic across VLANs – and risking a significant reduction in wireless performance – or blocking mDNS traffic to prevent connectivity for Bonjour-capable devices and services. Aruba AirGroup adds mDNS proxy capabilities to campus WLANs so that Bonjour messages can be forwarded across subnets or VLANs. 

For troubleshooting AirGroup issues,  debugging needs to be enabled for mDNS process under System, Security and User debug logs.
 
The log debug messages for the mDNS process are not enabled by default. To enable specific logging levels, use the following CLI commands in configuration mode:

To enable high level mDNS debug messages:

(host)(config) #logging level debugging system process mdns

To enable mDNS packet processing messages:

(host)(config) #logging level debugging system process mdns subcat messages

To enable mDNS CLI configuration messages:

(host)(config) #logging level debugging system process mdns subcat configuration

To enable mDNS Auth and CPPM user messages:

(host)(config) #logging level debugging user process mdns

To enable mDNS security debugging:


(host)(config) #logging level debugging security process mdns

Display AirGroup logs by issuing the following commands in the controller CLI:

show log all
 
show log system all
 
show log user all
 
show log user-debug all


Note: For the above show commands you can include the filter as "mdns"  
(show log system all | include mdns)
