How Devices Are Assigned To Multicast Vlans; Multicast Vlans And Multicast Claiming - Alcatel Omni Switch/Router User Manual

How Devices are Assigned to Multicast VLANs

If the recipients of the multicast traffic were defined using the port rule, each specified port is
then marked as a member of the multicast
If the recipients of the multicast traffic were defined using the
addresses of the receiving devices, no action is taken until a frame is received from one
MAC
of those devices. When such a frame is received, the switch learns the device, adds its
address to the filtering database, and marks the port on which the frame was received as a
member of the multicast

The source port of the multicast traffic (i.e., the port
through which multicast traffic enters the switch) can
be a member of any Group. The source port does not
need to be a member of the same Group as recipient
ports. Note that the source port does not become a
member of the multicast
Although some leakage may occur before devices are assigned to AutoTracker
leakage occurs in conjunction with device assignment to multicast

Multicast VLANs and Multicast Claiming

ing modules. However, multicast
