Service Manual

When the ACL rules change, the ACL and protocol-independent multicast (PIM) modules apply the new
rules automatically.
When you congure the SSM range, Dell Networking OS supports SSM for congured group range as well
as the default SSM range.
When you remove the SSM ACL, PIM SSM is supported for the default SSM range only.

[infinity] command.
Parameters
