3. In the
IP Multicast group
box, type the IP multicast address that has been
designated as the sending address for IP multicasting in Symposium Call
Center Server.
ATTENTION
The IP multicast addresses that support multicasting are
224.0.0.0 through 239.255.255.255,
but
the IP multicast addresses between
224.0.0.0 and 224.0.0.255 inclusive are reserved for routing and topology
discovery or maintenance protocols, and must not be used.
Check the Internet Engineering Task Force (http://www.ietf.org) and Internet
Assigned Numbers Authority (http://www.iana.org) web sites to review a
complete list of reserved IP multicast addresses before you select an address for
your internal multicast needs.
4. Accept the default IP port numbers for each statistics group.
ATTENTION
If using Symposium Web Client’s Real-Time Reporting
component as well as Nortel Remote Agent Observe, do not change the default
IP port numbers assigned to the statistics groups. Symposium Web Client’s
Real-Time Reporting component receives multicast statistics through these
ports and will malfunction if the port numbers are changed.
5. Change the Multicast time to live (TTL) value to a value that is appropriate for
your network.
ATTENTION
If packets are traveling through more than one router, you
should change the Multicast TTL value to a value that is appropriate for your
network and the number of routers that you use. If the TTL value is set too low,
the real-time multicast statistics may not reach your application. The Default
TTL value is 2 hops. Nortel recommends a value between 64 and 68 hops.
