SNMP Community Strings
An SNMP community string is a text string that acts as a password to authenticate messages sent between
the SNMP remote management application and the device (the SNMP agent). SNMP
Get
and
Get-next
requests are valid only if the community string in the request matches the community string at the device. If
the community strings do not match, either modify the community string at the device so that it is the string
that the management station expects, or modify the management station so that it uses the device’s
community strings.
The community string is included in every SNMPv1
and SNMPv2C packet transmitted between the SNMP
manager and the SNMP agent. This string is case sensitive, cannot be empty, and cannot exceed 32
characters.
Use this procedure to configure the read-only SNMP community string.

SNMP Authentication Traps
SNMP authentication traps occur in a number of conditions. By default, this option is disabled. In particular,
they can occur when the SNMP agent:
•
Receives a request that does not contain the correct community name.
•
Receives a request not sent from a member of the acceptable host list.
•
Receives a request from a bad user name or password when using SNMP Version 3.
•
Sends an authentication trap message to one or more trap destinations (management systems),
indicating authentication failure.
Use this procedure to configure SNMP authentication traps.
