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.
Change History
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)
XClarity Controller (XCC)
The following ports are used by XCC. Ports are either fixed or configurable as noted. For configurable ports, the default port is listed.
Chassis Management Module (CMM)
The Chassis Management Module (CMM and CMM2) is the service processor used in the Flex System Enterprise Chassis. The following ports are user configurable. The default port numbers used are indicated.
The following TCP/IP ports are fixed and cannot be changed.
Integrated Management Module and Integrated Management Module II (IMM2)
The following ports are user configurable. The default port numbers used are indicated.
The following TCP/IP ports are fixed and cannot be changed.
