SNMPv1 and SNMPv2c Overview

The Simple Network Management Program (SNMP) is another way for
you to manage the switch. This type of management involves viewing and
changing the management information base (MIB) objects on the device
using an SNMP application program.

The AT-S63 management software supports SNMPv1, SNMPv2c, and
SNMPv3. This chapter explains how to configure the switch’s software for
SNMPv1 and SNMPv2c. For instructions on how to configure the switch
for SNMPv3, refer to Chapter 22, ”SNMPv3” on page 419.

The procedures in this chapter show you how to create and manage
SNMPv1 and SNMPv2c community strings through which your SNMP
application program at your management workstation can access the
switch’s MIB objects.

You can also configure SNMPv1 and SNMPv2c with the SNMPv3 Table
menus described in Chapter 22, ”SNMPv3” on page 419. However,
because the SNMPv3 Table menus require a much more extensive
configuration, Allied Telesyn recommends configuring SNMPv1 and
SNMPv2c with the procedures in this chapter.

To manage a switch using an SNMP application program, you must do the
following:

ˆ

Activate SNMP management on the switch. The default setting for
SNMP management is disabled. The procedure for this can be found
in “Enabling or Disabling SNMP Management” on page 99.

ˆ

Load the Allied Telesyn MIBs for the switch onto your management
workstation containing the SNMP application program. The MIBs are
available from the Allied Telesyn web site at www.alliedtelesyn.com.

To manage a switch using SNMP, you need to know the IP address of the
switch or of a master switch and at least one of the switch’s community
strings. A community string is a string of alphanumeric characters that
gives you access to the switch.

A community string has several attributes that you can use to control who
can use the string and what the string will allow a network management to
do on the switch. The community string attributes are defined below:

Community String Name
You must give the community string a name. The name can be from one
to eight alphanumeric characters. Spaces are allowed.

Access Mode
This defines what the community string will allow a network manager to
do. There are two access modes: Read and Read/Write. A community
