The service list rule allows any type of message.
Multiple service maps of the same name with different sequence numbers can be created and the evaluation of the filters
will be ordered on the sequence number. Service lists are an ordered sequence of individual statements, each one has a
permit or deny result. Evaluation of service list consists of a list scan, in a predetermined order, and an evaluation of the
criteria of each statement that matches. A list scan is stopped once the first statement match is found and an action
permit/deny associated with the statement match is performed. The default action after scanning through the entire list
is to deny.
Step 7
In the
Service instance
text box, enter the service instance to match.
Step 8
In the
Custom
text box, enter the mDNS service type string to match.
The
Learned Service
box shows the services that are added after enabling the learned service type configured by
navigating to
Configuration
>
Controller
>
mDNS
>
Global
. For example, _roap._tcp.local. The
Selected Service
box shows the learned service that you have selected for an mDNS service.

What to Do Next
Proceed to enable the mDNS gateway and redistribution of services.
Enabling mDNS Gateway and Redistributing Services (CLI)
After enabling mDNS gateway for a device, you can apply filters (apply IN-bound filtering or OUT-bound
filtering) and active queries by using
service-policy
and
service-policy-query
commands, respectively. You
can redistribute services and service announcements using the
redistribute mdns-sd
command, and set some
part of the system memory for cache using the
cache-memory-max
command.
By default, mDNS gateway is disabled on all interfaces.
