Multicast Address Range

Vocera has a fixed address range to configure a multicast group. The Class D multicast address range for Vocera starts at 230.230.0.1 with a range of 4096 addresses.

You can configure the multicast address range by adding the following properties to the \vocera\server\Properties.txt file on each Vocera Voice Server:

IPBaseMulticastAddr—Specifies the start of the range. The default start of the range is 230.230.0.0.
IPMulticastRange—Specifies the number of addresses in the range. The default address in the range is 4096.

Note: If you modify the Properties.txt file, you must stop and start the Vocera Voice Server to load the properties into the memory.

Note: If you want to use the default range of 230.230.0.0 you do not have to update the server Properties.txt file.
