The following are the limitations of NMS and Metasys SNMP agent functionality:
-
NMS does not provide the ability to acknowledge and/or discard Alarms by using an SNMP Set message.
-
NMS cannot modify the supervisory device by using an SNMP Set message.
-
Metasys SNMP Agent functionality does not allow the NMS to detect when the supervisory device suffers a power failure or to initiate any action based on such detection.
-
SNMP Get requests are not proxied through the site; that is, you must query the device of interest directly and not through the Site Director.
-
With the SNMP Version 3 implementation, user authentication, and data encryption are not available for SNMP traps and Gets.
-
The Get Bulk request, which returns data from multiple objects with one request, is not supported.
