LACP Member Monitoring/Speed Mismatch Alert Suggestion

Hi all,

i would like ask all of you if someone knows a good solution how to trigger a speed mismatch against the configured link speed. I give you an example:

Bundle-Ether1 has a port description of "Core: device [40Gbit] {abc} (notes)". So the bundle should have 40Gbit and I want now to create an alert to trigger a speed mismatch if a member goes down, then Bundle-Ether1 will report its updated speed i.e. 30Gbit and this should be compared and trigger somehow.
