Individual Static mDNS Records
You can create individual static records independently for each record type.
Creating an Individual SRV Record
Use the following command to configure an individual SRV record:
airgroup static mdns-record srv <mac_addr> <domain_name> <port> <priority> <weight> <host_
name> [server_ipaddr]
Creating an Individual TEXT Record
Use the following command to configure an individual TEXT record:
airgroup static mdns-record txt <mac_addr> <domain_name> <text> [server_ipaddr]
Creating an Individual A Record
Use the following command to configure an individual A record:
airgroup static mdns-record a <mac_addr> <host_name> <ipv4addr> [server_ipaddr]
Creating an Individual AAAA Record
Use the following command to configure an individual AAAA record:
airgroup static mdns-record aaaa <mac_addr> < host_name> <ipv6addr> [server_ipaddr]
You can delete the mDNS records by appending no at the beginning of the command. Ensure that the [server_
ipaddr] parameter is not added while deleting mDNS records.

mDNS APVLANAggregation
In the AirGroup solution, all mDNS/SSDP packets are terminated in a controller. The AirGroup solution works
as a unicast querier and responder on behalf of mDNS/SSDP devices and eliminates the propagation of
multicast mDNS/SSDP traffic in the WLAN.
When a wired mDNS/SSDP device is part of a VLAN which is not trunked in a controller, L2 connectivity does
not exist between the wired mDNS/SSDP device and the controller. In such a scenario, the mDNS/SSDP
packets from the wired mDNS/SSDP device does not reach the controller or from the controller to the wired
mDNS/SSDP device. Hence, AirGroup does not discover these wired mDNS/SSDP devices.
The mDNS APVLANaggregation allows the discovery of wired mDNS/SSDP devices which do not have L2
connectivity with the controller or which do not trunk in the controller. An AP, which is in the same VLAN as the
wired mDNS/SSDP device which does not trunk in the controller, receives and forwards the mDNS/SSDP
packets from the wired mDNS/SSDP devices to the controller and from the controller to the wired mDNS/SSDP
device. The AP forms a separate split tunnel (0x8000)with the controller and aggregates all mDNS/SSDP traffic
to and from the controller.
l The split tunnel is formed only when both AP Multicast Aggregation (under AP System Profile) and
AirGroup parameters are enabled. If either AP Multicast Aggregation or AirGroup parameter is
disabled, the split tunnel is not formed.
l The AP Multicast Aggregation parameter is disabled by default.
l When AP Multicast Aggregation parameter is enabled from disabled state, an mDNS/SSDP device
discovery packet is sent to the VLAN in which the split tunnel is created if the AirGroup parameter is also
enabled.
l If an AP is provisioned with an uplink VLAN, then the split tunnel between the AP and the controller is
formed with the uplink VLAN, otherwise the native VLAN is used.
