When multicast is deployed on the MDU, the multicast is configured on the OLT through the cascade-port.

Sometimes, the OLT is connected to the MDU.

In this case, you must set the port connected to the MDU as the multicast cascade-port.

The configuration is as follows:

#

interface gpon 0/0
 ont add 0 ontid 0 sn-auth 32303131B39Fxxxx snmp ont-lineprofile-name MA5626_M
 ont ipconfig 0 0 static ip-address 10.10.0.3 mask 255.255.255.0 gateway 10.10.0.1 vlan 100
 ont snmp-profile 0 0 profile-id 10
#

#
