    Identified

    English

    We have identified that CRC errors are increasing due to a module and cable issue on a specific port connected to the IPS/IDS device at ICN04.

    We have temporarily disabled communication through the affected port. Although this has slightly reduced the overall network processing capacity, there is currently no impact on network communication.

    Given the current traffic levels, we do not anticipate any issues arising from the reduced capacity. We plan to replace the faulty component today without causing any service disruption.

    Korean

    ICN04의 IPS/IDS 장비에 연결된 특정 포트에서 모듈 및 케이블 문제로 인해 CRC 오류가 증가하고 있는 것을 확인하였습니다.

    해당 포트의 통신은 현재 일시적으로 차단된 상태이며, 이로 인해 네트워크 처리 용량이 다소 감소하였으나, 전체 네트워크 통신에는 영향을 미치지 않고 있습니다.

    현재의 트래픽 수준을 고려할 때, 감소된 용량으로도 서비스에는 전혀 문제가 없을 것으로 판단되며, 금일 중으로 서비스 중단 없이 관련 부품을 교체할 예정입니다.
