mDNS policies operation on WLC 8+

[andy!doesnt!like!uucp]

Hi there

i'm studying topic of mDNS policy utilization for limiting visibility of mDNS SPs & there are some inclarities in cisco docs.

1) i assume that when WLC makes a decision should he respond to client's query with specific SP it parses all mDNS policy list till the end and if MAC of the SP supplying service matches query + all the remaining conditions (such as location/role/userid) are met as well in each policy WLC traverses then WLC advertises SP to client. is my assumption correct?

2) there are some statements in the https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/multicast_broadcast_setup.html#bonjour-gway-based-on-access-policy:

Restrictions on Bonjour Gateway Based on Access Policy

• The total number of policies that can be created is same as the number of service instances that are supported on the platform. Hundred policies can be supported; 99 policies and one default policy.

What does Cisco mean here under "service instance"? is it single SP entry or service (like AirPlay)?

thanks in advance
