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.

Note

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 89 depicts the SIC SNMP support.

Use the show command to view all statistics counters available to the SNMP daemon. Table 26 list the MIBs used by the SIC to maintain accounting statistics.

Table 26: MIBs Used by the SIC for SNMP Statistics

MIB

Description

RFC4670.mib

Maintains accounting client statistics.

RFC4671.mib

Maintains accounting server statistics.

The SIC supports the traps described in Table 27.

Table 27: SNMP Traps Supported for the SIC

SNMP Trap

Description

diameter-base-protocol-error

Diameter base protocol error occurred.

diameter-peer-connection-down

Diameter peer connection is down.

diameter-permanent-failure

Diameter permanent failure occurred.

diameter-transient-failure

Diameter transient failure occurred.

sic-server-internal-error

An SIC server implementation–dependent error occurred.

sic-server-log-file-failure

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.

sic-server-resource-failure

An SIC server implementation—dependent resource failure occurred.

sic-server-shutdown

The SIC server process stopped successfully.

sic-server-startup

The SIC server process started successfully.

sic-server-unauthorized-administration-request

HTTP/HTTPs requests sent to the SIC server were denied because the user does not have proper permission to access the URL.
