Symptom:
1. 특정 서버의 NIC 중 일부(혹은 다수/전체) 포트가 통신 불가 상태로 확인됨
2. OA상에서 VC의 상태가 Degraded(성능저하) 상태로 확인되나, 다른 서버들의 통신 상태는 정상
3. VC의 "show all *" 로그를 확인하니, 특정 서버의 포트에서 loop-Protected Error가 확인됨.
이러한 경우, 해당 서버의 포트로 부터 loop 와 같은 Packet Storm 현상이 유발되었다고 판단할 수 있으며, VC Domain의 안정적인 통신을 유지하기 위해 VC에서 해당 요인/유발 서버의 포트를 비활성화한 것이다. (명확한 확인은 고객지원센터를 통해 확인하자)
