Hi,
Can anyone give me an example of filtering multicast traffic in direction from CM toward CMTS. I am using Cisco ubr10k for Multicast over Docsis where 4 freqs are spanned to other widebands. In Downstream direction everything is ok, but i wanted to filter possible injection of multicast traffic (from end users) in upstream direction.
You could add something like this to your CM config files :
SnmpMibObject docsDevFilterIpDefault.0 Integer 2; /* accept */
SnmpMibObject docsDevFilterIpIfIndex.20 Integer 1;
SnmpMibObject docsDevFilterIpDirection.20 Integer 1; /* inbound */
SnmpMibObject docsDevFilterIpProtocol.20 Integer 17;
SnmpMibObject docsDevFilterIpDaddr.20 IPAddress 224.0.0.0;
SnmpMibObject docsDevFilterIpDmask.20 IPAddress 240.0.0.0;
SnmpMibObject docsDevFilterIpStatus.20 Integer 4; /* createAndGo */
