Security
Please note:
SNMP v3 is the default for GET and traps. If you want to use SNMP v1 or v2 you need to change the related parameter settings (snmp_trap_version and snmp_v1v2_support) in /opt/nem/etc/snmpagentd.conf. For more information also see the related parameter definition in [1KHW002414] FOXMAN-UN under Linux - User Manual and application details given in [1KHW029203] FOXMAN-UN HLM SNMPv3 Integration - Application Note.
• SNMP V3 (default, recommended)
If required v3 security can be disabled via the parameter «snmp_v3_security», however it is not recommended to do that. One SNMP V3 user including authentication and privacy protocol can be set up via the «snmpagentd.conf» file using the parameters «snmp_v3_userid», «snmp_v3_auth_protocol» and «snmp_v3_priv_protocol» (see Installation of the SNMP daemon).
Additional users can be created by the initial user if he is given access to the USM and VACM tables via the parameter «snmp_v3_usm_access».
• SNMP V1 & V2c (not recommended)
The community field («snmp_community») of a read request is set to «public» by default. This string can be changed by editing the «snmpagentd.conf» file. Refer to Installation of the SNMP daemon for more details on the SNMP part of the configuration file.
