PurposeCommand or Action
•
(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).
ip pim spt-threshold {kbps | infinity}
[group-list access-list-number]
Step 3
Example:
Switch(config)# ip pim spt-threshold
•
For kbps, specify the traffic rate in kilobits per second. The default
is 0 kbps.
Because of switch hardware limitations, 0 kbps is the only
valid entry even though the range is 0 to 4294967.
Note
infinity group-list 16
•
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.
To return to the default setting, use the no ip pim spt-threshold
{kbps | infinity} global configuration command.
Note
Returns to privileged EXEC mode.end
Example:
Switch(config)# end
Step 4
Verifies your entries.show running-config
Example:
Switch# show running-config
Step 5
(Optional) Saves your entries in the configuration file.copy running-config startup-config
Example:
Switch# copy running-config
Step 6
startup-config
