Lists practices for service node capacity, cluster IDs, and network MTU consistency.
Follow these practices to maintain AppQoE service node capacity and reliable cluster communication:
-
To ensure that the service nodes have sufficient capacity for AppQoE services, don't configure any other features on devices that have been configured with the service node role.
-
When you create an AppQoE cluster containing service controllers and service nodes, ensure that all the cluster members have the same ID as the site.
-
Ensure that service controllers and service nodes that form a cluster share the same Cisco Catalyst SD-WAN site ID. If there’s a mismatch in the site IDs, the service nodes are reported as Yellow on the controller. This leads the service nodes being disregarded from the distribution of flows for optimization.
-
Ensure that the maximum transmission unit (MTU) size of the network connecting the service controllers and service nodes is uniform across the complete traffic path. Otherwise, it can lead to broken communication due to packet fragmentation.
