Managing multicast group memberships
To receive a multicast transmission, a client interface must join a specific multicast
group (a Class D IP address from 224.0.0.0 to 239.255.255.255). When data is sent to
an address in that range, it is multicast to all hosts that have joined that group.
The
mcast-service
profile provides a way to manage which multicast groups can be
accessed by a client interface. Each profile specifies a number of multicast groups (up
to 256), and a filter type. The filter type determines how the list of multicast groups is
used: to allow access only to those groups, or allow access to all groups except those
listed.
You can configure multiple
mcast-service
profiles, one for each level of multicast
services you provide. You can define the profiles locally or via RADIUS. You then
apply an
mcast-service
profile to a client interface by specifying the profile name in
the client’s
connection
or RADIUS profile (see “Configuring multicast client
Number of multicast clients per group
A Stinger IP2000 allows up to 1017 multicast clients per group. The following
restrictions apply:
■
Multicast groups from
224.0.0.100
through
224.0.0.160
are reserved for
internal use.
■
Multicast traffic is limited to a maximum of 542Mbps when the number of
multicast clients in a group is greater than 251.
If the number of multicast clients in a group exceeds 1017, a message such as the
following is displayed:
LOG info, Shelf 1, Controller-1, Time: 17:07:07--
We hit maximum number of client per multicast group for 239.100.100.1
