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)。
以下命令可在Cisco 3232C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
-
在交换机上设置SNMPv3用户以使用身份验证和加密：
show snmp user显示示例
(sw1)(Config)# snmp-server user SNMPv3User auth md5 <auth_password> priv aes-128 <priv_password> (sw1)(Config)# show snmp user ----------------------------------------------------------------------------- SNMP USERS ----------------------------------------------------------------------------- User Auth Priv(enforce) Groups acl_filter ----------------- --------------- --------------- --------------- ----------- admin md5 des(no) network-admin SNMPv3User md5 aes-128(no) network-operator ----------------------------------------------------------------------------- NOTIFICATION TARGET USERS (configured for sending V3 Inform) ----------------------------------------------------------------------------- User Auth Priv ----------------- ------------------ ------------ (sw1)(Config)# -
在ONTAP 端设置SNMPv3用户：
security login create -user-or-group-name <username> -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212显示示例
cluster1::*> system switch ethernet modify -device "sw1 (b8:59:9f:09:7c:22)" -is-monitoring-enabled-admin true cluster1::*> security login create -user-or-group-name <username> -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CSHM配置为使用新SNMPv3用户进行监控：
system switch ethernet show-all -device "sw1" -instance显示示例
cluster1::*> system switch ethernet show-all -device "sw1" -instance Device Name: sw1 IP Address: 10.231.80.212 SNMP Version: SNMPv2c Is Discovered: true SNMPv2c Community String or SNMPv3 Username: cshm1! Model Number: N3K-C3232C Switch Network: cluster-network Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 9.3(7) Reason For Not Monitoring: None <---- displays when SNMP settings are valid Source Of Switch Version: CDP/ISDP Is Monitored ?: true Serial Number of the Device: QTFCU3826001C RCF Version: v1.8X2 for Cluster/HA/RDMA cluster1::*> cluster1::*> system switch ethernet modify -device "sw1" -snmp-version SNMPv3 -community-or-username <username> cluster1::*> -
确认要使用新创建的SNMPv3用户查询的序列号与CSHM轮询周期完成后上一步中详述的序列号相同。
system switch ethernet polling-interval show显示示例
cluster1::*> system switch ethernet polling-interval show Polling Interval (in minutes): 5 cluster1::*> system switch ethernet show-all -device "sw1" -instance Device Name: sw1 IP Address: 10.231.80.212 SNMP Version: SNMPv3 Is Discovered: true SNMPv2c Community String or SNMPv3 Username: SNMPv3User Model Number: N3K-C3232C Switch Network: cluster-network Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 9.3(7) Reason For Not Monitoring: None <---- displays when SNMP settings are valid Source Of Switch Version: CDP/ISDP Is Monitored ?: true Serial Number of the Device: QTFCU3826001C RCF Version: v1.8X2 for Cluster/HA/RDMA cluster1::*>
