SAP Announcements

Encoded Media hardware encoder appliances automatically broadcast the availability of multicast channels via the means of SAP announcements.

To allow SAP announcements

• The Encoded Media appliance in question must be configured with at least one multicast channel
• Your firewall must allow SAP announcements to pass on port 9875

To test for SAP announcements

Announcements are broadcast on multicast group 239.255.255.255 port 9875. Testing for these packets is a simple, two step process using McTest.

1. Download and run Encoded Media's free McTest tool from the downloads page.
2. Paste the SAP group 239.255.255.255:9875 into the IP address field at the top and tap Start.
