SNMP and Alarm Traps
SNMP Traps
SNMP traps are automatically sent by the agent towards the NMS (network
management station) to report errors in the device or in the affected service. To
enable fault isolation by the NMS, the traps include specific information about
the problem status, such as: start/end time), port number/type and the type of
problem, such as: LOS, LOF, LCD, and so on.
Standard SNMP traps, such as cold start and authentication failure, are also
supported. Additionally, alarm traps to be sent are user-selectable and can be
masked per manager.
Alarm Traps
ACE-3105, ACE-3205 supports a hierarchical alarm traps mechanism. This
mechanism generates alarm traps according to a configurable alarm traps mask
per manager. All traps are reported in the system event log, even when masked.
Traps can also be disabled when selected for masking by manager. The recording
of events in the event log cannot be disabled.
The alarm traps that are implemented in ACE-3105, ACE-3205 are listed in
Chapter 6
.
Management
Cross-Network Management
Management traffic streams can pass through ACE-3105, ACE-3205
transparently, using predefined destination subnet IDs. ACE-3105, ACE-3205
delivers the management traffic over pseudowire or ATM VC connections,
allowing frames to pass over a packet-switched network or from one network to
another without interruption.
If the originating management subnet is received on the inband Ethernet port, it
can be translated to an ATM VC subnet, and vice-versa, as needed in the
application.
