Controlled Multicast Configuration Example - 3Com 8800 Configuration Manual

Caution:
In local user view, before executing this command, you must configure user service
type to LAN-ACCESS, which is the only one supported by controlled multicast at
present.

26.3.3 Controlled Multicast Configuration Example

I. Network reuirements
As shown in Figure 26-1, HostA and HostB join the multicast group. Layer 3 multicast is
enabled on LSA, LSB, LSC and LSD. Controlled multicast is enabled on LSA and LSC.
Because controlled multicast combines multicast with 802.1x, 802.1x should be
enabled on LSA and LSC.

III. Configuration procedure
Controlled multicast is combined with 802.1x, so you need to perform the following
configuration beside multicast configuration:
Enable controlled multicast globally.
[SW8800] ip managed-multicast
Enable 802.1x globally.
[SW8800] dot1x
Enable 802.1x on the controlled ports (the access ports for LSA and LSC).
