SwitchCommunityStringAlert、因为集群网络交换机上的社区字符串无效或缺失

适用场景

• ONTAP 9
• AFF
• FAS
• 集群网络交换机
  • CN1610
  • Cisco Nexus交换机

问题描述

• 重新启动FAS/AFF后 SwitchCommunityString_Alert、集群交换机运行状况监控器(Cluster Switch Health Monitor、CSHM)将触发运行状况警报。
• 此操作将生成以下 Active IQ 通知：

HA Group Notification (Health Monitor process cshm: SwitchCommunityString_Alert[switch01]) ALERT

• system health subsystem show将交换机运行状况子系统报告为已降级。

Cluster::> system health subsystem show
Subsystem      Health
----------------- ------------------
SAS-connect     ok
Environment     ok
Memory       ok
Service-Processor ok
Switch-Health    degraded

• system health alert show命令将显示以下错误：

Cluster::> system health alert show
        Node: Node-04
      Resource: cluster-sw-01(serial-number)
      Severity: Major
   Indication Time: Wed Sep 14 13:45:36 2022
      Suppress: false
        Acknowledge: false
   Probable Cause: Ethernet switch "Cluster-sw-01(serial-number)" with IP
           address "10.XX.XX.XX" is not reachable via SNMP.
           Incorrect SNMP community string might be configured on the Ethernet switch.
   Possible Effect: Ethernet switch communication problems and accessibility issues.
 Corrective Actions: Check the SNMP community string on the Ethernet switch
           to verify that the expected community string is configured.
                   Use the "system switch ethernet show -snmp-config" command to view the expected
                     community string.

• CSHM-SWITCH-CONFIG.XML 通过 ASUP 显示以下错误。

Switch Monitoring Status： false
Reason For Not Monitoring：Invalid SNMP Settings
