Description

Management standard

Provides system reachability (ping)
check during system discovery and
before other operations

ICMP is a required protocol tightly
integrated with IP. ICMP messages are
delivered in IP packets and are used
for out-of-band messages related to
network operation.

Systems Insight Manager can use
ICMP messages to ping a managed
system. However, some routers block
ICMP messages so Systems Insight
Manager provides an alternative ping
using TCP.

ICMP

System identification, inventory and
events

Part of the SNMP specification, the
MIB is a model of the information to
be managed through SNMP. It is
equivalent to the CIM defined by
WBEM.

MIB

System identification, Inventory and
events

SNMP is widely used for management
but the widely implemented versions
1 and 2 have weak security. While
no set operations are used by Systems
Insight Manager, read access to
system data might be visible on the
network. SNMP is UDP-based. In many
environments it is not considered a
suitable protocol to pass through the
firewall. Because SNMPv1 has a
simple, clear-text community, it
provides a low level of security.
However, SNMP can be suitable for
some environments in which the
network used for managing systems is
relatively controlled.

SNMP

Remote tool execution

SSH is used for remote command
execution. Systems Insight Manager
uses SSH to run commands on
managed systems.

SSH

Consistent server management across
vendors

A DMTF initiative for common server
management which enables
vendor-independent management
applications.

SMASH

System identification

An SNIA standard for storage
management using WBEM.

SMI-S

Identification, inventory, and events

A DMTF program with widespread
industry support with a set of
standards including CIM, CIM-XML,
and WS-Management. The CIM-XML
protocol is most widely used with
WBEM today, and the term WBEM is
often used to mean this protocol.

Note: Configure firewalls to allow the
CMS to communicate with managed
systems through default port 5989. If
you have modified the default port
setting for your WBEM provider, you
must configure your firewall for the
port number your WBEM provider on
which it is actually configured.
