Configurare SNMPv3

Collaboratori netapp-yvonneo aclose-ntap

Seguire questa procedura per configurare SNMPv3, che supporta il monitoraggio dello stato dello switch Ethernet (CSHM).

Informazioni su questo compito

I seguenti comandi configurano un nome utente SNMPv3 sugli switch Broadcom BES-53248:

  • Per nessuna autenticazione: snmp-server user SNMPv3UserNoAuth NETWORK-OPERATOR noauth

  • Per l'autenticazione MD5/SHA: snmp-server user SNMPv3UserAuth NETWORK-OPERATOR [auth-md5|auth-sha]

  • Per l'autenticazione MD5/SHA con crittografia AES/DES: snmp-server user SNMPv3UserAuthEncrypt NETWORK-OPERATOR [auth-md5|auth-sha] [priv-aes128|priv-des]

Il seguente comando configura un nome utente SNMPv3 sul lato ONTAP : cluster1::*> security login create -user-or-group-name SNMPv3_USER -application snmp -authentication-method usm -remote-switch-ipaddress ADDRESS

Il seguente comando stabilisce il nome utente SNMPv3 con CSHM: cluster1::*> system switch ethernet modify -device DEVICE -snmp-version SNMPv3 -community-or-username SNMPv3_USER

Passi

  1. Impostare l'utente SNMPv3 sullo switch per utilizzare l'autenticazione e la crittografia:

    show snmp status

    Mostra esempio 
    (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. Impostare l'utente SNMPv3 sul lato ONTAP :

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

    Mostra esempio 
    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. Configurare CSHM per il monitoraggio con il nuovo utente SNMPv3:

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

    Mostra esempio 
    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. Verificare che il numero di serie da interrogare con l'utente SNMPv3 appena creato sia lo stesso specificato nel passaggio precedente una volta completato il periodo di polling CSHM.

    system switch ethernet polling-interval show

    Mostra esempio 
    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
