Known Affected Releases
Symptom: The problem is observed as a complete loss of traffic on a monitorred port of a Cat4948 running 122-25.EWA14. Upon duplex mismatch the Catalyst 4948 doesn't log a warning or preferrably puts the mismatched port into error disabled state. Conditions: The scenario involves a local SPAN and duplex mismatch on the monitored port. Upon duplex mismatch the monitorred port will cease passing traffic completely without going into errored or any other state state.
