industry standard known as SMUX that allows one or more SNMP Sub-Agents to connect to a single SNMP Master Agent using a TCP SMUX

SNMP spport varia3le(s)The SNMPStartparameter is defined within each .km. The ,out of box-default setting for this parameter is

the active state. If active, SNMPStartlaunches the PATROL SNMP Master Agent (snmpmagt) if it is not startedalready. SNMPStartthen starts the SNMP Sub-Agent.

The configuration of the PATROL SNMP Sub Agent is controlled by the values contained in the PATROLconfiguration file.

On UNIX, it is $PATROL_HOME/lib/config.default

On Windows NT, it is %PATROL_HOME%\lib\ config.default

The important variables are:

"/snmp/support" = { REPLACE="yes" },

"/snmp/agent_auto_start" = { REPLACE="yes" },

"/snmp/default_port" = { REPLACE="161" },

"/snmp/master_agent_port" = { REPLACE="1161" },
