FSP Backup ip=40.6.5.1 MTMS=9125-F2C*02C6986
FSP Backup ip=40.6.7.1 MTMS=9125-F2C*02C69D6
FSP Primary ip=40.6.10.2 MTMS=9125-F2C*02C6A46 FR006-CG12-SN005-DR1
Important: The output of lsnwcomponents indicates that the cluster contains a single
78AC-100 frame FR006 with three supernodes: SN004 with 4x9125-F2C servers in cages
7-10, SN005 with 4x9125-F2C servers in cages 11-14, and SN051 with 4x9125-F2C
servers in cages 3 - 6.

4.2.6 Verify that a multicast tree is present and correct

A missing or incorrect multicast tree causes communication issues on the service network,
such as nodes that fail to communicate with or ping each other. Verify the presence and
integrity of the multicast tree, as shown in Example 4-20.

If the multicast tree is incorrect (for example, if it does not include all the expected cages),
remove the file, re-ipl the CECs, and recycle CNM.
