Installing and Configuring the SNMP Agent

WARM | COLD Custom Configuration Parameters
for the RUN Command
If an SNMPCTL file already exists in the run subvolume (when you stop and restart an
SNMP agent process), the SNMP agent uses the existing configuration values.
The SNMPCTL File and the COLD Startup Parameter
When you start the SNMP agent using the COLD startup parameter and no SNMPCTL
file exists in the run subvolume, the SNMP agent creates an empty SNMPCTL file. You
must explicitly set each configuration value to be stored in the SNMPCTL file using the
RUN command parameters.
When you start the SNMP agent specifying the COLD startup parameter and an
SNMPCTL file already exists in the run subvolume, the SNMP agent purges the
existing SNMPCTL file and creates an empty SNMPCTL file. You must explicitly set
each configuration value to be stored in the empty SNMPCTL file using the RUN
command. Values set when the COLD parameter is specified persist only as long as
the agent process is running.
Here is an example of the RUN command in which the COLD parameter is specified:
RUN SNMPAGT /NAME $ZSNMP, NOWAIT/ COLD
Use SCF or SNMP to configure all components of the SNMP agent. (See Part II, SCF
for the SNMP Agent , for more information on SCF for SNMP.)
COLD and WARM Configuration Scenarios.
Note. To stop and restart an SNMP agent using the default configuration, you must stop the
SNMP agent, purge the existing SNMPCTL file, and then restart the SNMP agent process
using the WARM option.

How Is the SNMP Agent Configured?
COLD Yes/No The SNMP agent creates an SNMPCTL file
after purging any existing file by that name
in the run subvolume. The SNMPCTL file
must then be explicitly configured.
WARM Yes
No SNMPCTL file exists in the run
subvolume. The SNMP agent creates an
SNMPCTL file in the run subvolume and fills
it with default values.
WARM No An SNMPCTL file exists in the run
subvolume. The SNMP agent opens the
SNMPCTL file and is configured with the
values specified in the SNMCTL file.
