Summary
Missing VLAN requirement
Error
No multicast traffic has been heard from node ppm on the MULTICAST_PORT port for over 3 minutes even though the node appears to be up. Please check your multicast routing, server.conf settings, and/or firewall settings.
Cause
ip pim sparse-mode is not enabled on the VLAN
The Multicast tests, provided by support, may work and the cluster may initially start and acknowledging multicast traffic is functional. However after some time the No Multicast traffic messages are generated.
Fix
Have the Network Administrator enable ip pim sparse-mode
Commands to see the VLAN settings:
sh run int vl <vlannumber>
or
sh ip pim interface
