按照此操作步骤 配置SNMPv3、此配置支持交换机日志收集和交换机运行状况监控(SHM)。
关于此任务
以下命令用于在NVIDIA SN2100交换机上配置SNMPv3用户名：
-
对于*无身份验证*：
net add snmp-server username SNMPv3用户 auth-none -
对于* MD5/SHA身份验证*：
net add snmp-server username SNMPv3用户[auth-md5_auth-sha]AUTH-password -
对于采用AES/DES加密的* MD5/SHA身份验证*：
net add snmp-server username SNMPv3用户[auth-md5_auth-sha]AUTH-password[encrypt-AES_encrypt-des]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
以下命令使用SHM建立SNMPv3用户名：cluster1：：：：*> system switch Ethernet modify -device device-snmp-version SNMPv3 -commune-or-username SNMPv3用户

在交换机上设置SNMPv3用户以使用身份验证和加密：

在ONTAP 端设置SNMPv3用户：
security login create -user-or-group-name SNMPv3User -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212显示示例
cluster1::*> security login create -user-or-group-name SNMPv3User -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212 Enter the authoritative entity's EngineID [remote EngineID]: Which authentication protocol do you want to choose (none, md5, sha, sha2-256) [none]: md5 Enter the authentication protocol password (minimum 8 characters long): Enter the authentication protocol password again: Which privacy protocol do you want to choose (none, des, aes128) [none]: aes128 Enter privacy protocol password (minimum 8 characters long): Enter privacy protocol password again:

将SHM配置为使用新的SNMPv3用户进行监控：
system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance显示示例
cluster1::*> system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance Device Name: sw1 (b8:59:9f:09:7c:22) IP Address: 10.231.80.212 SNMP Version: SNMPv2c Is Discovered: true DEPRECATED-Community String or SNMPv3 Username: - Community String or SNMPv3 Username: cshm1!
