Abstract
The systems management processors integrated in ThinkSystem, System x, Flex System, and BladeCenter servers use a variety of TCP/IP ports for communication. This document lists them and indicates which ones the administrator can and cannot change. You need to ensure that your network (firewalls and routers) allows communications through these ports for the management processor to function properly.

Changes in the August 3, 2022 update:
- In XCC, added SNMP traps (UDP), port 162 (configurable) - XCC section
Introduction
The systems management processors (also known as service processors) integrated in ThinkSystem, System x, Flex System, and BladeCenter servers use a variety of TCP/IP ports for communication. This document lists them and indicates which ones the administrator can and cannot change. You need to ensure that your network (firewalls and routers) allows communications through these ports for the management processor to function properly.
The management processors covered are:
- XClarity Controller (XCC)
- Chassis Management Module (CMM and CMM2)
- Integrated Management Module II (IMM2 and IMM2.1)
- Integrated Management Module (IMM)
- BladeCenter Advanced Management Module (AMM)
- BladeCenter Management Module (MM)
- Remote Supervisor Adapter II (RSA II)
- Baseboard Management Controller (BMC)
