4.2(7a) 5.2(2a)

Description (partial)

Symptom:When using Port-monitor delta thresholds, a trap may not be sent at the next polling cycle for any port on the linecard if an interface on the linecard changes state. Once the port state stabilizes, traps will resume being sent.

Conditions:Occurs on the initial polling cycle after a port changes state when the delta threshold counter has incremented sufficiently to trigger the delta alert.
