The PATROL SNMP architecture comprises an SNMP subagent that is part of the BMC PATROL Agent and an SNMP Master Agent that is a separate, external process.

PATROL SNMP Component Definitions describes the role that each component plays in the BMC PATROL SNMP architecture.

Note

Port 161 is an industry standard, while port 8161 is a BMC PATROL standard. By running on port 8161, you can avoid possible conflicts with operating system vendors who are already using port 161 for an SNMP agent.

Following figure shows the relationships among the PATROL SNMP Master Agent, the BMC PATROL Agent, BMC PATROL SNMP subagents, SNMP subagents, and the SNMP manager. It also lists their default port numbers.
