Configurare SNMPv3 per monitorare lo stato degli switch IP MetroCluster
Suggerisci modifiche
PDF
Nelle configurazioni IP di MetroCluster, è possibile configurare SNMPv3 per monitorare lo stato degli switch IP.
Questa procedura illustra i passaggi generici per configurare SNMPv3 su uno switch. Alcune delle versioni del firmware dello switch elencate potrebbero non essere supportate in una configurazione IP MetroCluster.
È necessario seguire i passaggi per una versione del firmware dello switch supportata in una configurazione IP MetroCluster. Fare riferimento a "Hardware Universe" per verificare le versioni del firmware supportate.

I seguenti comandi vengono utilizzati per configurare un nome utente SNMPv3 sugli switch Broadcom, Cisco e NVIDIA:
Configurare un OPERATORE DI RETE con nome utente SNMPv3 sugli switch Broadcom BES-53248.
|
|
A partire da ONTAP 9.20.1, puoi configurare l'autenticazione SHA-512 sugli switch Broadcom. |
-
Per nessuna autenticazione:
snmp-server user <snmpv3-user> NETWORK-OPERATOR noauth -
Per l'autenticazione MD5/SHA/SHA-512:
snmp-server user <snmpv3-user> NETWORK-OPERATOR [auth-md5|auth-sha|auth-sha512] -
Per l'autenticazione MD5/SHA/SHA-512 con crittografia AES/DES:
snmp-server user <snmpv3-user> NETWORK-OPERATOR [auth-md5|auth-sha|auth-sha512] [priv-aes128|priv-des]
Il seguente comando configura un nome utente SNMPv3 sul lato ONTAP:
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 <switch-name> -snmp-version SNMPv3 -community-or-username <snmpv3-user>-
Configura l'utente SNMPv3 sullo switch per utilizzare l'autenticazione SHA e la crittografia AES-128:

Configurare CSHM per il monitoraggio con il nuovo utente SNMPv3:
cluster1::*> system switch ethernet modify -device "sw1" -snmp-version SNMPv3 -community-or-username SNMPv3shaAes128
