问题

暂时断开交换机管理电缆后，节点上的交换机 SNMP 配置似乎有所不同

SNMP 社区字符串已更改为未知值
SNMP 版本已从 SNMPv3 更改为 SNMPv2c

可以观察到更改的值并将其与未更改的开关进行比较。示例：

aff::> system switch ethernet show -device ciscosw-3.sub.domain.com(FLMAABBCCHY)

Device Name: ciscosw-3.sub.domain.com(FLMAABBCCHY)

IP Address: xxx.xxx.xxx.xxx

SNMP Version: SNMPv3

Is Discovered: true

Community String or SNMPv3 Username: operaator_cisco

Model Number: N9K-C9336C-FX2

Switch Network: storage-network

Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 10.4(5)

Reason For Not Monitoring: None

Is Monitored ?: true

Serial Number of the Device: FLMAABBCCHY



aff::> system switch ethernet show -device ciscosw-4.sub.domain.com(FLMDDEEFFQR)

Device Name: ciscosw-4.sub.domain.com(FLMDDEEFFQR)

IP Address: xxx.xxx.xxx.xxx

                  SNMP Version: SNMPv2c

Is Discovered: true

Community String or SNMPv3 Username: cshm1!

Model Number: N9K-C9336C-FX2

          Serial Number of the Device: Unknown





aff::> system switch ethernet show -device * -status
