Introduction to SNMP 1-1
1
Introduction to SNMP
Network management is a broad term, including workstation
configuration, assignment of IP addresses, network design,
architecture, network security, and topologies. All this can fall within
the scope of a network manager.
Any protocol for managing networks must allow virtually all
network devices and systems to communicate statistics and status
information to network management stations (network managers).
This communication must be independent of the primary network
transmission medium and impose little effect on the efficiency of the
network. Network managers must be able to obtain status
information from managed devices, and make changes in the way the
managed devices handle network traffic. Simple Network
Management Protocol (SNMP) is one way of meeting these
requirements.
SNMP Management
SNMP is a mechanism for network management that is complete, but
simple. It is designed on the manager/agent paradigm, with the
agent residing in the managed device. Information is exchanged
between agents (devices on the network being managed) and
managers (devices on the network through which management is
done).
There are many possible transactions between agents and managers.
These transactions vary widely with the different types of devices
that can be managed. With so many varied requirements for
reporting and management, the list of commands a manager must be

1
1-2 E/OS SNMP Support Manual
Introduction to SNMP
able to issue is overwhelming, and every new manageable device can
increase the list. SNMP was created to allow all these things to be
easily done on any growing network.
SNMP operates on a simple fetch/store concept. With SNMP the
available transactions between manager and agent are limited to a
handful. The manager can request information from the agent or
modify variables on the agent. The agent can respond to a request by
sending information, or if enabled to do so, voluntarily notify the
manager of a change of status on the agent (issue a trap).
With SNMP, administrators can manage the switch configuration,
faults, performance, accounting, and security from remote SNMP
management stations.
SNMP Simplified SNMP is the only network management protocol that is widely
available from many vendors of TCP/IP networks and
internetworks.
SNMP:
• Allows network management with a simple set of commands.
• Allows new devices added to a network to be easily managed
with minimal intervention.
• Is adequate for many basic network management needs.
• Is generalized for application to networks other than TCP/IP,
such as IPX and OSI.
• Provides considerable versatility for managing a great many
types of devices.
• Allows all networks to employ the same method for
management.
SNMP Commands A manager requests information from an agent by sending a single
command, the Get command. The Get command also has a variation
(GetNextRequest) that permits more efficient operation:
• GetRequest – Requests the value of a specified variable on the
agent. This command is used to retrieve management data.
• GetNextRequest – Requests the value of the next variable after
the one specified in the command. This command is used to
retrieve lists and tables of management data.

1
SNMP Management 1-3
Introduction to SNMP
An agent responds to a request by sending a single command, the
GetResponse command. This command contains the requested
information.
A manager changes information (variables) in the agent by sending a
single command, the SetRequest command. This command is used to
manipulate management data.
A trap is used by an agent to report extraordinary events. Refer to
Traps and Their Purpose on page 1-5.
Figure 1-1 SNMP Commands and Responses
Why Variables Exist
In a Managed
Device
Variables are the means by which a switch or director (and other
devices) keep track of their performance, control their own
performance, and provide access to their performance for network
managers. A simple example of a variable’s use is to set a port offline
and turn the port back on. Some variables just hold values that
indicate status (for example error counts). SNMP allows the network
managers to have access to some of the same variables for network
management.
For purposes of the following explanation, an object is a data variable
that represents an attribute of a managed device.
How SNMP Changes
Variables (Objects)
in a Managed
Device
An agent is the entity that interfaces to the actual object being
managed (Figure 1-2 on page 1-4). The agent understands the
language of SNMP and translates between the manager and the
object. Objects may be retrieved and/or modified by the manager,
and it is the agent’s job to return the requested object’s value. Within
the agent is at least one, maybe several, collections of definitions

Introduction to SNMP
called Management Information Bases (MIBs). When an agent
supports a standard MIB, it agrees to provide and make available the
variables listed in the MIB.
A MIB is a hierarchical tree of groups and variables. Operators at a
network management station enter a command with supported
groups and variables from the MIB.
Figure 1-2 Retrieving or Setting Values Using MIBs
Standard MIBs Standard MIBs are those created and approved by IETF and other
Internet standards bodies and are readily available for use with
SNMP network management stations. The standard MIBs provide a
baseline of common operations across a wide variety of managed
devices. Chapter 2 describes the standard MIBs used by the various
McDATA products.
Standard MIBs supported by McDATA products are:
• MIB-II (Internet MIB) as described in RFC 1213: supported by all
switches and directors.
• Fibre Alliance (FCMGMT) MIB, version 3.1: supported by EFC
Server, Sphereon 4500 Fabric Switch, Sphereon™ 3216 Fabric
Switch, Sphereon 3232 Fabric Switch, Intrepid™ 6064 Director,
Intrepid 6140 Director, ES-3016, ES-3032, and ED-6064.

Private Enterprise
MIBs Private MIBs are those provided by the manufacturer of the managed
devices to allow management of device-specific items. Chapter 2
describes the McDATA private MIBs in more detail.
The McDATA private enterprise MIBs are:
• es1000 MIB, used by the ES-1000 switch
• ed5000 MIB, used by the ED-5000 director
• fcEos MIB, used by the Sphereon 4500 Fabric Switch, Sphereon
3232 Fabric Switch, Sphereon 3216 Fabric Switch, ES-3016 and
ES-3032 switches, and the Intrepid 6064 and Intrepid 6140
directors (updated to support zoning, port binding, threshold
alerts, and open trunking).
Traps and Their
Purpose Traps are unsolicited status reports, or status change indicators a
managed object sends to a network manager. The destination address
for traps is a configuration item for each managed agent.

Support
Overview
SNMP is a protocol that uses the User Data Protocol (UDP) to
exchange messages between an SNMP agent (in a managed device)
and a management station residing on a network. Although SNMP
can be made available over other protocols, McDATA only supports
UDP.
To be monitored and managed remotely by a network management
station, each switch or director is equipped with an SNMP agent. This
agent is a software process within the switch that receives
management requests and generates corresponding responses by
accessing the data specified for the MIB-II, Fabric Element MIB, Fibre
Alliance MIB, and FCEOS enterprise specific MIB. In addition, the
agent gives each switch the ability to notify a management station
when an important event occurs by sending a trap to the
management station.
Five MIBs are supported:
• A subset of the Standard MIB-II for TCP/IP –based Internet as
specified in RFC1213.
• Fabric Element MIB containing support for FL ports as specified
in Fibre Channel standards.
• Fibre Alliance MIB (also referred to as the FC Management MIB).
• FCEOS MIB, the McDATA enterprise specific MIB supporting the
McDATA switch and director firmware.
