SummaryExinda sending broadcast from management interface
OverviewExinda uses UDP port 33333 when the appliances are part of a cluster. The Exinda will broadcast cluster information relating to traffic to other Exindas in the cluster.
This traffic should only be seen on an interface with the cluster role selected - not on any other interface. These broadcast packets contain details of the optimizer processing that has been done - this is picked up by all other appliances in the cluster and is used to synchronise optimization state, ensuring other devices in the cluster have the traffic details of the bridging Exindas.
If the cluster is enabled on the management interface this will lead to the broadcast being sent through the network and you could see high CPU utilization on switches that are connected to the Exinda.
