Summary: Configurazione SNMPV3 di NetWorker

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Instructions

Nella NetWorker Administration Guide sono disponibili istruzioni per la configurazione delle trap SNMPV3.  Deve essere utilizzato per la configurazione iniziale, insieme a KB: Come configurare NetWorker per l'utilizzo di SNMP.

L'articolo seguente fornisce un esempio funzionante dei file di configurazione sul sistema operativo Linux.

Di seguito è riportata una configurazione di esempio fornita a un cliente che ha consentito il corretto funzionamento di un'ambiente trap SNMPV3 non funzionante.

 /etc/snmp/snmpd.conf
# Please see /usr/share/doc/packages/net-snmp/EXAMPLE.conf for a
# more complete example and snmpd.conf(5).
#
# Writing is disabled by default for security reasons.  If you'd like
# to enable it uncomment the rwcommunity line and change the community
# name to something nominally secure (keeping in mind that this is
# transmitted in clear text).

# don't use ' < > in strings for syslocation or syscontact
# Note that if you define the following here you won't be able to change
# them with snmpset
# syslocation Server Room
# syscontact Sysadmin (root@localhost)

# These really aren't meant for production use.  They include all MIBS
# and can use considerable resources.  See snmpd.conf(5) for information
# on setting up groups and limiting MIBS.

# sec.name source community

I valori evidenziati vengono ottenuti e impostati dalle proprietà del server NSR:

NOTA: Eventuali modifiche ai file di configurazione richiedono il riavvio di snmpd e snmptrapd.
 

Test

Avviare una sessione PuTTY sull host del ricevitore di trap (potrebbe anche essere il server NetWorker) ed eseguire:
snmptrapd -f -C -c /etc/snmp/snmptrapd.conf -Le -M /usr/share/snmp/mibs -m NETWORKER-MIB
*Nota: Aggiunta dell'opzione -D per l'output

di debug Avviare una seconda sessione PuTTY dal server NetWorker ed eseguire:
nsrtrap -i 3 -v trapreceiver_hostname
This is a V3 Test
ctrl <D>
In caso di successo, dovresti vedere nel registro per la tua prima sessione di stucco;

Configurazione delle notifiche di backup:

Sul server trap SNMP, eseguire il seguente comando:

snmptrapd -f -C -c /etc/snmp/snmptrapd.conf -Le -M /usr/share/snmp/mibs -m NETWORKER-MIB &

Nota;

  • La configurazione del backup a livello di azione supporta solo SNMPv2
  • La configurazione del backup a livello di policy supporta sia SNMPv2 che v3
/usr/sbin/nsrtrap trapreceiver_hostname -i 3
