  • Page 11: Snmp Security

    SNMP Security Community strings provide a basic form of access control in SNMP v2 (PowerDsine PowerView is based on SNMP v2). Whenever a community string is defined, it must be provided along with any basic SNMP query, if the requested operation is to be permitted by the device. Community strings usually allow read-only or read-write access to the entire device.
