Multicast Statistics

Channel statistics are available for leaf connections on the BME end. However, channel statistics are

not available for the root connection on the BME end.

For the example in Figure 27-5, execute the following commands to display channel statistics for the

leaf connections:

• dspchstats 12.1.50.75 on BPX switch 1 (available)

• dspchstats 5.2.75.40 on BPX switch 2 (available)

• dspchstats 11.9.123.432 on BPX switch 3 (available)

For the example in Figure 27-5, the following command will not display channel statistics (because

5.1.75.0 is a root connection):

• dspchstats 5.1.75.0 on BPX switch 2 (not available)
