Flashsystem : Behavior when the management IP port cable is disconnected

If the cable of the node with the management IP on the side with the management IP is disconnected, there will be no SNMP signal or syslog signal forever.

    If you have a secondary Ethernet port configured, when there is a port failure on the node, or the cable is unplugged, outbound traffic will automatically switch to the other port and you will continue getting SNMP traps or call home.

    If there is a network issue upstream, the system will not automatically switch ports.

    1番の管理ポートのケーブルが抜けている時、私が最も問題と感じているのは、障害発生時にコールホームのメールもSNMPトラップも出ません。スペアを消費尽くしても、電源の片方が壊れても、LANケーブルが1本抜ているだけで、誰も気付きません。問題が発覚するのは、FlashSystemが停止した時です、間違いなくパニックになります。
    When the cable on the first management port is unplugged, what I find most problematic is that no call home emails or SNMP traps go out when a failure occurs. Even if you consume all the spares or one of the power supplies breaks, no one will notice because one LAN cable is unplugged. The problem will be discovered when the FlashSystem stops, and there will definitely be a panic.
