Chapter 5: SNMPv1 and SNMPv2 Community Strings
Section I: Basic Operations 82
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-S62 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 17, SNMPv3 Configuration on page
222.
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 17, SNMPv3 Configuration on page 222.
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:
❑ 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 85.
❑ 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:
