Reading SNMP objects is not password-protected. However, a password is required for
read access in SNMP, but this is set to "public", which is usual for network devices, and
cannot be modified. By default upon delivery, the password for write access is "private" and
can be changed by the user.
Another benefit for the user is the option of sending traps using the Simple Network
Management Protocol.
Management Information Base (MIB)
Database, which contains all the data (objects and variables) required for network
management.
Agent
An agent is a software tool, which collects data from the network device on which it is
installed, and transmits this data on request. Agents reside in all managed network
components and transmit the values of specific settings and parameters to the
management station. On a request from a manager or on a specific event, the agent
transmits the collected information to the management station.
Traps
Traps are spontaneous SNMP alarm or information messages, which are sent by an
SNMP-compatible device when specific events occur. Traps are transmitted with
maximum priority to various addresses (if required) and can then be displayed by the
management station in plain text. The IP addresses that are to receive these traps (trap
targets/receivers) must be set by the user on the relevant device. The following traps are
used:
trapColdStart
trapPortUp/Down
SNMP, the web interface, Telnet, and the serial terminal all use the same password,
which can be changed by the user.
