按照以下步骤配置 SNMPv3，SNMPv3 支持以太网交换机健康监控 (CSHM)。

关于此任务

以下命令用于在 Broadcom BES-53248 交换机上配置 SNMPv3 用户名：

  • 对于*无需身份验证*的情况： snmp-server user SNMPv3UserNoAuth NETWORK-OPERATOR noauth

  • 用于 MD5/SHA 认证： snmp-server user SNMPv3UserAuth NETWORK-OPERATOR [auth-md5|auth-sha]

  • 用于*MD5/SHA认证与AES/DES加密*： snmp-server user SNMPv3UserAuthEncrypt NETWORK-OPERATOR [auth-md5|auth-sha] [priv-aes128|priv-des]

以下命令在ONTAP端配置 SNMPv3 用户名： cluster1::*> security login create -user-or-group-name SNMPv3_USER -application snmp -authentication-method usm -remote-switch-ipaddress ADDRESS

以下命令用于在 CSHM 中建立 SNMPv3 用户名： cluster1::*> system switch ethernet modify -device DEVICE -snmp-version SNMPv3 -community-or-username SNMPv3_USER

步骤

  1. 在交换机上配置 SNMPv3 用户以使用身份验证和加密：

    show snmp status

    显示示例 
    (sw1)(Config)# snmp-server user <username> network-admin auth-md5 <password> priv-aes128 <password>

(cs1)(Config)# show snmp user snmp

     Name            Group Name      Auth Priv
                                     Meth Meth    Remote Engine ID
----------------- ------------------ ---- ------ -------------------------
<username>        network-admin      MD5  AES128 8000113d03d8c497710bee

  2. 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::*> 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:

  3. 配置 CSHM 以使用新的 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 (b8:59:9f:09:7c:22)" -instance

                                   Device Name: sw1
                                    IP Address: 10.228.136.24
                                  SNMP Version: SNMPv2c
                                 Is Discovered: true
DEPRECATED-Community String or SNMPv3 Username: -
           Community String or SNMPv3 Username: cshm1!
                                  Model Number: BES-53248
                                Switch Network: cluster-network
                              Software Version: 3.9.0.2
                     Reason For Not Monitoring: None  <---- should display this if 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>

  4. 在 CSHM 轮询周期结束后，验证使用新创建的 SNMPv3 用户查询的序列号是否与上一步中详细说明的序列号相同。

    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: 10.228.136.24
                                  SNMP Version: SNMPv3
                                 Is Discovered: true
DEPRECATED-Community String or SNMPv3 Username: -
           Community String or SNMPv3 Username: <username>
                                  Model Number: BES-53248
                                Switch Network: cluster-network
                              Software Version: 3.9.0.2
                     Reason For Not Monitoring: None  <---- should display this if 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
