Description
Restricts a user's device administration rights.
It gives specific users the rights to manage
specified objects on devices and therefore
provides fine management.
Authenticates and encrypts the packets
transmitted between the NM station and
managed devices. This prevents data packets
from being intercepted or modified,
improving data sending security.
Identifies particular faults. An administrator
uses error codes to quickly locate and rectify
faults. The more error codes received, the
more they help an administrator in device
management.
Sent from managed devices to the NM
station. These traps allow an administrator to
discover device faults immediately.
After sending traps, the managed devices do
not require the acknowledgement from the
NM station.
Sent from managed devices to the NM
station.
The managed devices require the
acknowledgement from the NM station after
sending informs. If a managed device does
not receive an acknowledgement after
sending an inform, it will resend the inform
to the NM station and generate alarm logs.
Even if the NM station restarts, it can still
synchronize the informs sent during the
restart process.
If the managed device does not receive an
acknowledgement from the NM station after
sending an inform, it will store the inform in
its memory. In this regard, using informs may
consume lots of system resources.
