Table 238: Controller model and number of supported mDNS servers
In a multi-controller deployment with AirGroup solution:
l The local controller sends the response from an mDNS device for iChat service to other controllers in the
cluster. This is in addition to local controller performing L2 multicast of the message to all VLANs.
l The corresponding controller multicasts the message to all the VLANs that are trunked in it.
l When a user moves from one controller to another controller, two user entries exist in the user cache for
the same user until the user entry is deleted from the first controller. The two user entries exist because the
IP address, which is part of the mDNS payload, changes when a user moves from one controller to another
controller. If IP mobility is enabled, only one user entry exists because the user retains the IP address across
the controllers.
