Proxy Agent; Setting The Community Name - Sun Microsystems Fire V20z Management Manual

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 OS 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 90.

Setting the Community Name

The SNMP agent on the SP acts as a proxy for the SNMP agent running on the
platform. (Refer to "Configuring SNMP on Your Server" on page 88.) To proxy
properly, you must use the community string. The community string needed to do
so is the value defined when you configured the platform for SNMP.
If you find that your SNMP queries are not being proxied to the platform SNMP
agents, validate that the community string on the SP matches that on the platform.
The SP proxy community string can be changed to match the platform community
string using the following command:
# sp set snmp proxy community
There are no restrictions on the length of the community strings; common names are
private and public. The default name is public.
For more information, refer to "SP Set SNMP Proxy Community Subcommand" on
page 277.
