1.Customer under the dslam 5100 always got two same multicast traffic packets and that cause a lot of mosaic.
2.But multicast service under dlsam 5600 is ok.
There is no any alarm.
But in the dslam 5100 that connect to the switch , we can use command to check the size of the multicast service is 5.8 M.
normally the size is only 2.9 M.
There are two method:
1. undo the static group in the ne40;
2. undo the vlan that connect to the dslam 5100.
The multicast source is in the site and in the ne40 's port we config
the static multicast group.
More detail , please check the attahment.
don't permit all vlan in the switch to the dslam if the multicast soure is in the site.
or don't config the multicast static group if the multicast soure is in the site.
