reverse path tree has enabled the PIM-SSM protocol.

If a static group is configured for an any-source multicast (*,G), a

source address cannot subsequently be defined for this group without

first deleting the entry.

If a static group is configured for one or more source-specific multicasts

(S,G), an any-source multicast (*,G) cannot subsequently be defined

for this group without first deleting all of the associated (S,G) entries.

Using the no form of this command to delete a static group without

specifying the source address will delete all any-source and source-
specific multicast entries for the specified group.

The switch supports a maximum of 16 static group entries.

multicast hosts on the subnet may support any of the IGMP versions

If the switch receives an IGMP Version 1 Membership Report, it sets a

timer to note that there are Version 1 hosts which are members of the

group for which it heard the report.
