Chapter 3 SNMP Server Management 45
SNMP Agent on the Service Processor
The SNMP agent running on the SP facilitates the management and monitoring of
the server. The SNMP agent can be used to query various types of SP information.
Refer to
FIGURE 3-1 for a list of the MIBs; refer to TABLE 3-3 for a detailed description
of the MIBs.
There is no configuration required to use this functionality other than integrating the
server MIBs with your desired management station.
Refer to the procedure for using the SNMP agent on the SP, as explained in
“Integrating MIBs with Third-Party Consoles” on page 43.
Note – The SNMP agent on these servers supports SNMP v1/v2c. For security
reasons, there are no settable attributes in this agent.
Proxy Agent
The SP acts as an SNMP proxy agent intermediary for the platform. Queries made
from a management station to the SNMP agent on the SP are intercepted by the
proxy agent on the SP and forwarded to the platform; the SP proxy agent contacts
the platform to retrieve the requested information. The proxy agent then receives the
data from the platform and sends the request back to the management station. The
management station never knows that the request was proxied. The SP and the
platform communicate over an internal private network.
To enable this facility, you must first run an SNMP agent on your platform operating
system (see your operating system vendor to obtain this agent). This enables
platform-level management transparently through the SP. Querying MIBs other than
the server MIB (for example, the Host Resource MIB) and the MIBII System MIB on
the SP obtains information from the platform by proxying the request to the
platform SNMP agent.
Ensure that the SP can identify the read-only and read-write community names that
are configured for your platform SNMP agent. Refer to “Setting the Community
Name” on page 46.
