Purpose
Enables privileged EXEC mode. Enter your password if prompted.
Enters global configuration mode.
Creates a standard access list.
• For access-list-number, the range is 1 to 99.
• The deny keyword denies access if the conditions are matched.
• The permit keyword permits access if the conditions are matched.
• For source, specify the multicast group to which the threshold will
apply.
• (Optional) For source-wildcard, enter the wildcard bits in dotted
decimal notation to be applied to the source. Place ones in the bit
positions that you want to ignore.
The access list is always terminated by an implicit deny statement for
everything.
Specifies the threshold that must be reached before moving to
shortest-path tree (spt).
• For kbps, specify the traffic rate in kilobits per second. The default
is 0 kbps.
Because of device hardware limitations, 0 kbps is the only
Note
valid entry even though the range is 0 to 4294967.
• Specify infinity if you want all sources for the specified group to
use the shared tree, never switching to the source tree.
• (Optional) For group-list access-list-number, specify the access
list created in Step 2. If the value is 0 or if the group list is not used,
the threshold applies to all groups.
