SNMP Support for the SIC Overview (SRC CLI)
The Simple Network Management Protocol (SNMP) implementation for the SIC supports alerts and is based on an external SNMP agent that accesses the SIC server agent.
You can query status using an SNMP Get command, and you can receive alert notifications through SNMP traps from the agent manager. However, you cannot configure the SIC server using SNMP because the SIC does not support the SNMP Set command.
SNMP support for the SIC functions in the same manner as other SRC components. The SIC has its own subagent, which communicates with the main SRC SNMP daemon using the AgentX protocol. The subagent registers with the main daemon for all relevant object identifiers (OIDs). Traps are communicated from the subagent to the main daemon. Figure 1 depicts the SIC SNMP support.
Use the show command to view all statistics counters available to the SNMP daemon. Table 1 list the MIBs used by the SIC to maintain accounting statistics.

The SIC supports the traps described in Table 2.

Diameter base protocol error occurred.
Diameter peer connection is down.
Diameter permanent failure occurred.
Diameter transient failure occurred.
An SIC server implementation–dependent error occurred.
Operation on an SIC server log file such as opening, reading, or writing failed. This is most likely due to the server disk being out of space.
An SIC server implementation—dependent resource failure occurred.
The SIC server process stopped successfully.
The SIC server process started successfully.
HTTP/HTTPs requests sent to the SIC server were denied because the user does not have proper permission to access the URL.
