Using the COLLECTOR Startup Parameter
Using the COLLECTOR Startup Parameter
To cause both primary and backup agent processes to send events to an EMS
collector other than $0, include the COLLECTOR startup parameter when you start the
SNMP agent. For example:
RUN SNMPAGT/NAME $ZSNMP, NOWAIT/ COLLECTOR $ACOL
Although HP does not recommend doing so, you can suppress output of SNMP agent
events altogether by including the COLLECTOR startup parameter with no argument:
RUN SNMPAGT/NAME $ZSNMP, NOWAIT/ COLLECTOR
This approach is the only way to suppress event logging. You cannot suppress event
logging through SCF.
For more information on the COLLECTOR startup parameter, refer to COLLECTOR
[$alternate-collector-process] on page 2-9.
Using the SCF ALTER PROCESS Command
You can also specify that the agent process send its events to an alternate collector by
issuing an SCF ALTER command against the PROCESS object and specifying a new
value for the EMSCOLL attribute. For example:
ALTER PROCESS $ZSNMP, EMSCOLL $ACOL
Configuring Security
Before the SNMP agent processes an SNMP request, the SNMP agent authenticates
the request to determine whether the SNMP manager is qualified to perform the
operation in the request. The request authentication rules implemented by the SNMP
agent depend on whether the SNMP manager is communicating through NonStop
Kernel IPC calls or through the TCP/IP UDP transport protocol.
Authenticating Requests Received Over TCP/IP
To configure the basis on which the SNMP agent accepts or rejects requests from
SNMP managers that communicate through TCP/IP, build an authentication table.
Each entry in the authentication table is one instance of a PROFILE object, or one row
in the SNMP agent’s private zagInProfileTable. You can configure, request information
about, and manage authentication table entries in two ways:
•
By issuing SNMP Set requests against the SNMP agent’s zagInProfile group
objects from an SNMP manager that uses NonStop Kernel IPC calls to
communicate with the SNMP agent.
•
By issuing SCF commands against PROFILE objects.
