What is the upper limit for adding airgroup service-id strings?
Controller might be blocking certain airgroup services based on the Airgroup configuration. If WLAN administrator wish to allow few blocked services per his network requirement, he could create a new service name and add the blocked service id(s) to the list. Until 188.8.131.52, airgroup service id exceeding 32 strings/characters cannot be added. Starting 184.108.40.206 and 220.127.116.11, upto 128 strings/characters are supported.
To add airgroup service id:
IAP(config)# airgroupservice SONOS
IAP(Config-SONOS)# id "urn:schemas-upnp-org:device:ZonePlayer:1"
