The following section describes operational considerations for deploying Application Telemetry, including general considerations, followed by a summary of platform-specific considerations.
The following list describes general Application Telemetry operational considerations:
When you enable Application Telemetry, it is globally enabled on all ports. You cannot disable the feature on a per-port basis.
Application Telemetry supports IPv4 and IPv6 packets, although host monitoring is available for IPv4 hosts only.
Application Telemetry filter rules are not user configurable. However, an updated app-telemetry.pol file can be installed through the ExtremeCloud IQ ‑ Site Engine.
If a user-created filter rule (ACL) conflicts with an Application Telemetry defined filter, the user-created rule always takes precedence.
There are two configurable sFlow collectors (Collector 1 and Collector 2). However, Application Telemetry uses Collector 1 only and you must configure it before enabling Application Telemetry.
Application Telemetry supports Segmented Management Instance interfaces VLAN and CLIP. Segmented Management Instance interface OOB is not supported.
Application Telemetry supports user created VRFs when you configure a Segmented Management Instance CLIP interface as the source IP.
You can use the onboarding VLAN to manage the switch and enable Application Telemetry without any additional management or routing interface configuration.
This section provides a summary of operational considerations for different switches.
