Oct 22, 2020
- Cisco LAN Switch Software
Known Affected Releases
Symptom: interface starts to flap without any fiber cable connection to the transceiver that is plugged into Fa1/6 , for example when GLC-FE-100FX is inserted. When a cable is inserted and port is shut/no shut to come out of err-disable state, no problem is seen. Conditions: SFPs that don't squelch RX-LOS data signal AND with no cable connection. Problem may not happen until neighboring ports are also inserted with other sfps.
