PurposeCommand or Action
By default, the output of the show ip mroute command
with the active keyword displays information about active
sources sending traffic to groups at a rate greater than or
equal to 4 kb/s. To display information about active
sources sending low-rate traffic to groups (that is, traffic
less than 4 kb/s), specify a value of 1 for the kb/s
argument. Specifying a value of 1 for this argument
displays information about active sources sending traffic
to groups at a rate equal to or greater than 1 kb/s, which
effectively displays information about all possible active
source traffic.
Note
Group: 239.1.2.3, (?)
Source: 10.0.0.1 (?)
Rate: 20 pps/4 kbps(1sec), 4 kbps(last 30
secs), 4 kbps(life avg)
