18.1.3 SNMP v3 and Authentication
SNMP v3 adds the use of groups and users to enhance security for SNMP management.
Groups are assigned access rights to SNMP objects. Users are members of groups and are
therefore limited to the access rights the group has. In addition users can also be required to
authenticate before conducting SNMP management sessions.
" SNMP v3 is enabled by creating SNMP groups and users. Once SNMP v3 is
enabled, SNMP community should be configured for SNMP v1 and/or v2c
access.
