AirGroup mDNS Static Records
AirGroup processes mDNS packets advertised by servers and creates the relevant cache entries. When a query
comes from a user, AirGroup responds with the appropriate cache entries with the relevant policies applied.
Starting with ArubaOS 6.4, AirGroup provides the ability for an administrator to add the mDNS static records
to cache, when a server is:
l not mDNS compliant.
l connected to a VLAN that is not trunked to the AirGroup supported controller.
The administrator can add these records manually to the cache using CLI commands for the servers that
adhere to the above conditions.
Important Points to Remember
Remember the following points when you create mDNS static records and add them to the cache:
l The mDNS static records do not expire as there is no cache refresh for static records. These static records
can be deleted by an administrator.
l The Administrator needs to ensure that the relevant records are updated manually, when the IP address of
a server is changed.
l The Disallow role policy configured on the CLI is accepted for static records. The Disable service policy is
accepted while responding to a query. Administrator has the privilege to configure static records of a
disabled service. Disallow vlan is not applicable for static records.
l ClearPass Policy Manager policies work with static servers.
Creating mDNS Static Records on a Controller
The Administrator can create the static records using the following methods:
l Group mDNS static records
l Individual mDNS static records
Group mDNS Static Records
You can create a group of mDNS records for a device. This section describes how to create static records of a
server as a group using the CLI.
Creating a PTR Record
Use the following command to create a PTR record:
(config) # airgroup static mdns-record ptr <mac_addr> <mdns_id> <domain_name> [server_ipaddr]
(config-airgroup-record) #
After creating a PTR record, controller displays the (config-airgroup-record) # prompt and you can create SRV, A,
AAAA, and TXT records under this prompt.
After creating a PTR, SRV, TXT, A, and AAAA static record, you can use the show airgroup cache entries command
to view and verify the records created. You can view only the static records in the output of the show airgroup cache
entries static command.
