Configurar SNMPv3 para supervisar el estado de los conmutadores IP de MetroCluster

Colaboradores netapp-aoife
PDF

En las configuraciones IP de MetroCluster, puede configurar SNMPv3 para supervisar el estado de los switches IP.

Este procedimiento muestra los pasos genéricos para configurar SNMPv3 en un conmutador. Es posible que algunas de las versiones de firmware del conmutador mencionadas no sean compatibles con una configuración IP de MetroCluster.

Debe seguir los pasos para una versión de firmware del conmutador compatible con una configuración IP de MetroCluster. Consulte la "Hardware Universe" para verificar las versiones de firmware compatibles.

Nota
Acerca de esta tarea

Los siguientes comandos se utilizan para configurar un nombre de usuario SNMPv3 en los conmutadores Broadcom, Cisco y NVIDIA:

Switches Broadcom

Configure un OPERADOR DE RED DE nombre de usuario SNMPv3 en los conmutadores Broadcom BES-53248.

  • Para sin autenticación:

    snmp-server user SNMPv3UserNoAuth NETWORK-OPERATOR noauth

  • Para autenticación MD5/SHA:

    snmp-server user SNMPv3UserAuth NETWORK-OPERATOR [auth-md5|auth-sha]

  • Para autenticación MD5/SHA con cifrado AES/DES:

    snmp-server user SNMPv3UserAuthEncrypt NETWORK-OPERATOR [auth-md5|auth-sha] [priv-aes128|priv-des]

El siguiente comando configura un nombre de usuario SNMPv3 en el lado ONTAP:

security login create -user-or-group-name SNMPv3_USER -application snmp -authentication-method usm -remote-switch-ipaddress ADDRESS

El siguiente comando establece el nombre de usuario SNMPv3 con CSHM:

cluster1::*> system switch ethernet modify -device DEVICE -snmp-version SNMPv3 -community-or-username SNMPv3_USER
Pasos

  1. Configure el usuario SNMPv3 en el conmutador para que utilice autenticación y cifrado:

    show snmp status
    (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. Configure el usuario SNMPv3 en el lado ONTAP:

    security login create -user-or-group-name <username> -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212
    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. Configure CSHM para monitorizar con el nuevo usuario de SNMPv3:

    system switch ethernet show-all -device "sw1" -instance
    cluster1::*> system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance

                                   Device Name: sw1

cluster1::*>
cluster1::*> system switch ethernet modify -device "sw1" -snmp-version SNMPv3 -community-or-username <username>

  4. Después de esperar el período de sondeo de CSHM, verifique que el número de serie esté completo para el conmutador Ethernet.

  1. Configure el usuario SNMPv3 en el conmutador para que utilice autenticación y cifrado:

    nv show system snmp-server
    cumulus@sw1:~$ nv show system snmp-server
                      applied
--------------------  ---------------------------------------
[username]            SNMPv3_USER
[username]            limiteduser1
[username]            testuserauth
[username]            testuserauthaes
[username]            testusernoauth
trap-link-up
  check-frequency     60
trap-link-down
  check-frequency     60
[listening-address]   all
[readonly-community]  $nvsec$94d69b56e921aec1790844eb53e772bf
state                 enabled
cumulus@sw1:~$

  2. Configure el usuario SNMPv3 en el lado ONTAP:

    security login create -user-or-group-name SNMPv3User -application snmp -authentication-method usm -remote-switch-ipaddress 10.231.80.212
    cluster1::*> security login create -user-or-group-name SNMPv3User -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. Configure CSHM para monitorizar con el nuevo usuario de SNMPv3:

    system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance
    cluster1::*> system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance
                                   Device Name: sw1 (b8:59:9f:09:7c:22)
                                    IP Address: 10.231.80.212
                                  SNMP Version: SNMPv2c
                                 Is Discovered: true
DEPRECATED-Community String or SNMPv3 Username: -
           Community String or SNMPv3 Username: cshm1!
                                  Model Number: MSN2100-CB2FC
                                Switch Network: cluster-network
                              Software Version: Cumulus Linux version 5.11.0 running on Mellanox Technologies Ltd. MSN2100
                     Reason For Not Monitoring: None
                      Source Of Switch Version: LLDP
                                Is Monitored ?: true
                   Serial Number of the Device: MT2110X06399  <---- serial number to check
                                   RCF Version: MSN2100-RCF-v1.9X6-Cluster-LLDP Aug-18-2022

cluster1::*>
cluster1::*> system switch ethernet modify -device "sw1 (b8:59:9f:09:7c:22)" -snmp-version SNMPv3 -community-or-username SNMPv3User

  4. Compruebe que el número de serie que se va a consultar con el usuario SNMPv3 recién creado es el mismo que se detalla en el paso anterior después de que se haya completado el período de sondeo de CSHM.

    system switch ethernet polling-interval show
    cluster1::*> system switch ethernet polling-interval show
         Polling Interval (in minutes): 5

cluster1::*> system switch ethernet show-all -device "sw1 (b8:59:9f:09:7c:22)" -instance
                                   Device Name: sw1 (b8:59:9f:09:7c:22)
                                    IP Address: 10.231.80.212
                                  SNMP Version: SNMPv3
                                 Is Discovered: true
