| 按照此操作步骤配置SNMPv3、此SNMPv3支持以太网交换机运行状况监控(CSHM)。 | ||
|
|
||
| .关于此任务 | ||
| 以下命令可在Cisco 92300YC交换机上配置SNMPv3用户名： | ||
|
|
||
| * 对于*no authentication (无身份验证)*： | ||
| `snmp-server user _SNMPv3_USER_ NoAuth` | ||
| * 对于*MD5/SHA身份验证*： | ||
| `snmp-server user _SNMPv3_USER_ auth [md5|sha] _AUTH-PASSWORD_` | ||
| * 对于采用AES/DES加密的*MD5/SHA身份验证*： | ||
| `snmp-server user _SNMPv3_USER_ AuthEncrypt auth [md5|sha] _AUTH-PASSWORD_ priv aes-128 _PRIV-PASSWORD_` | ||
|
|
||
|
|
||
| 以下命令会在ONTAP 端配置SNMPv3用户名：`cluster1：：：*> security login create -user-or-group-name _SNMPv3用户_-application snmp -authentication-method USM -remote-switch-ipaddress _address_` | ||
|
|
||
| 以下命令将使用CSHM建立SNMPv3用户名： | ||
| `cluster1::*> system switch ethernet modify -device _DEVICE_ -snmp-version SNMPv3 -community-or-username _SNMPv3_USER_` | ||
|
|
||
| .步骤 | ||
| . 在交换机上设置SNMPv3用户以使用身份验证和加密： | ||
| + | ||
| `show snmp user` | ||
|

| 以太网交换机运行状况监控器(CSHM)负责确保集群和存储网络交换机的运行状况、并收集交换机日志以进行调试。此操作步骤将引导您完成设置和开始从交换机收集详细的*Support*日志的过程，并开始每小时收集由AutoSupport收集的*定期*数据。 | ||
|
|
||
| .步骤 | ||
| . 要设置日志收集、请对每个交换机运行以下命令。系统会提示您输入交换机名称、用户名和密码以收集日志。 | ||
| + | ||
| `s系统交换机以太网日志设置密码` | ||
|
|
||
| + | ||
| .显示示例 | ||

| cluster1::*> *system switch ethernet log setup-password* | ||
| Enter the switch name: *<return>* | ||
| The switch name entered is not recognized. | ||
| Choose from the following list: | ||
| *cs1* | ||
| *cs2* | ||
| cluster1::*> *system switch ethernet log setup-password* | ||
| Enter the switch name: *cs1* | ||
| Would you like to specify a user other than admin for log collection? {y|n}: *n* | ||
| Enter the password: *<enter switch password>* | ||
| Enter the password again: *<enter switch password>* | ||
| cluster1::*> *system switch ethernet log setup-password* | ||

| Enter the password: *<enter switch password>* | ||
| Enter the password again: *<enter switch password>* | ||
| ---- | ||
| ==== | ||
| . 要开始收集日志、请运行以下命令、将device替换为上一命令中使用的交换机。这将开始两种类型的日志收集：详细的*Support*日志和每小时收集*定期*数据。 | ||
| + | ||
| `system switch ethernet log modify -device _<switch-name>_ -log-request true` | ||

| Enabling cluster switch log collection. | ||
| cluster1::*> *system switch ethernet log modify -device cs2 -log-request true* | ||
| Do you want to modify the cluster switch log collection configuration? {y|n}: [n] *y* | ||

| 等待10分钟、然后检查日志收集是否完成： | ||
|
|
||
| + | ||
| `system switch ethernet log show` | ||
|
|
||

|
|
||
| CAUTION: 如果其中任一命令返回错误或日志收集未完成、请联系NetApp支持部门。 | ||
|
|
||
|
|
||
|
|
||
| .故障排除 | ||
| 如果遇到日志收集功能报告的以下任一错误状态(在的输出中可见) `system switch ethernet log show`)、请尝试相应的调试步骤： | ||
|
|
||
| |=== | ||
|
|
||
|
|
||
| | *日志收集错误状态* | *分辨率* | ||
|
|
||
|
|
||
| a| | ||
| *RSA密钥不存在* | ||
| a| | ||
| 重新生成ONTAP SSH密钥。请联系NetApp支持部门。 | ||
|
|
||
|
|
||
|
|
||
| a| | ||
| *交换机密码错误* | ||
| a| | ||
| 验证凭据、测试SSH连接并重新生成ONTAP SSH密钥。查看交换机文档或联系NetApp支持部门以获取相关说明。 | ||
|
|
||
|
|
||
|
|
||
| a| | ||
| *对于FIPS*，ECDSA密钥不存在 | ||
| a| | ||
| 如果启用了FIPS模式、则需要在重试之前在交换机上生成ECDSA密钥。 | ||
|
|
||
|
|
||
|
|
||
| a| | ||
| *已找到已有日志* | ||
| a| | ||
| 删除交换机上先前的日志收集文件。 | ||
|
|
||
|
|
||
|
|
||
| a| | ||
| *交换机转储日志错误* | ||
| a| | ||
| 确保交换机用户具有日志收集权限。请参阅上述前提条件。 | ||
