由于交换机端口故障、Cisco集群交换机ISL端口关闭
适用场景
- ONTAP 9
- Cisco N9K-C933NC-NX2-集群 交换机
问题描述
- 两个集群交换机的事件日志均会报告以下ISL关闭警报：
[Node-01: cshmd: hm.alert.raised:alert]: Alert Id = SwitchIslIfDownWarn_Alert , Alerting Resource = Cluster_sw1(FDOXXXXXXXX)/Ethernet1/36 raised by monitor ethernet-switch
[Node-01: cshmd: hm.alert.raised:alert]: Alert Id = SwitchIslIfDownWarn_Alert , Alerting Resource = Cluster_sw2(FDOXXXXXXXH)/Ethernet1/36 raised by monitor ethernet-switch
- 系统运行状况警报报告以下信息：
::> system health alert show
Node: Node-01
Alert ID: SwitchIslIfDownWarn_Alert
Resource: Ethernet1/36
Severity: Major
Indication Time: Tue Jan 14 05:29:26 2025
Suppress: false
Acknowledge: false
Probable Cause: The cable attached to the ISL port
"Cluster_sw1(FDOXXXXXXXX)/Ethernet1/36" with the
description of "Intra-Cluster Switch ISL Port 1/36
(port channel)" might be faulty. For the port-channel,
please check each individual link.
Possible Effect: Inter- or Intra- cluster redundancy might be lost.
Corrective Actions: 1) Check whether the cable is fully inserted into the interface port on both ends.
2) Reconnect the ISL port using another cable. After
reconnecting it, verify whether the link of the ISL
port is up by executing the commands per the switch
configuration guide or by checking whether the Link
status LED is on.
- 因此、交换机运行状况将降级。
- ISL端口状态在交换机日志中显示为down：

在某些情况下、可将该等信息报告为不受支持：
`show logging log`
SW1 %ETHPORT-3-IF_UNSUPPORTED_TRANSCEIVER: Transceiver on interface Ethernet1/35 is not supported
SW2 %ETHPORT-3-IF_UNSUPPORTED_TRANSCEIVER: Transceiver on interface Ethernet1/35 is not supported
- 但是，根据Hardware Universe，支持使用的电缆。
- 更换交换机的受影响ISL端口之间的SFP/Cable不能解决问题描述问题。
