設定 SNMPv3

貢獻者

請遵循此程序來設定支援乙太網路交換器健全狀況監控（ CSHM ）的 SNMPv3 。

關於這項工作

以下命令可在 Broadcom BS-53248 交換器上設定 SNMPv3 使用者名稱：

  • 若為 * 無驗證 * ： snmp-server user SNMPv3UserNoAuth NETWORK-OPERATOR noauth

  • 對於 *MD5/SHA 驗證 * ： snmp-server user SNMPv3UserAuth NETWORK-OPERATOR [auth-md5|auth-sha]

  • 對於採用 AES/DES 加密的 * MD5/SHA 驗證 * ： snmp-server user SNMPv3UserAuthEncrypt NETWORK-OPERATOR [auth-md5|auth-sha] [priv-aes128|priv-des]

下列命令可在ONTAP Sfeside上設定一個v3使用者名稱：「cluster1：：*>安全登入create -user-or group name MPv2_user-applicationSNMP -imize-method USM -reme-switch-ipaddress_address_」

下列命令會使用 CSHM 建立 SNMPv3 使用者名稱： cluster1::*> system switch ethernet modify -device DEVICE -snmp-version SNMPv3 -community-or-username SNMPv3_USER

步驟

  1. 設定交換器上的v3使用者使用驗證和加密：

    show snmp status

    顯示範例 
    (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. 設定位在邊上的v3使用者ONTAP ：

    security login create -user-or-group-name <username> -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212

    顯示範例 
    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. 設定 CSHM 以監控新的 SNMPv3 使用者：

    system switch ethernet show-all -device "sw1" -instance

    顯示範例 
    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. 驗證要與新建立的 SNMPv3 使用者查詢的序號、是否與 CSHM 輪詢期間結束後上一步所述相同。

    system switch ethernet polling-interval show

    顯示範例 
    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
