command. Press <Enter>.

Enabling SNMP Management Access
The switch can be configured to accept management commands from Simple Network Management Protocol
(SNMP) applications. You can configure the switch to (1) respond to SNMP requests or (2) generate SNMP
traps.
When SNMP management stations send requests to the switch (either to return information or to set a
parameter), the switch provides the requested data or sets the specified parameter. The switch can also be
configured to send information to SNMP managers (without being requested by the managers) through trap
messages, which inform the manager that certain events have occurred.
Community Strings
Community strings are used to control management access to SNMP stations, as well as to authorize SNMP
stations to receive trap messages from the switch. You therefore need to assign community strings to specified
users or user groups, and set the access level.
The default strings are:
public - Specifies read-only access. Authorized management stations are only able to retrieve MIB
objects.
private - Specifies read-write access. Authorized management stations are able to both retrieve and
modify MIB objects.
To prevent unauthorized access to the switch via SNMP, it is recommended that you change the default
community strings.
To configure a community string, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt, type “snmp-server community string
mode”, where “string” is the community access string and “mode” is rw (read/write) or ro (read only).
Press <Enter>.
2. To remove an existing string, simply type “no snmp-server community string”, where “string” is the
community access string to remove. Press <Enter>.
Console(config)#snmp-server community abc rw
Console(config)#snmp-server community private
Console(config)#
If you do not intend to utilize SNMP, it is recommended that you delete both of the
default community strings. If there are no community strings, then SNMP
management access to the switch is disabled.
