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.
Note: 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.
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>.
Trap Receivers
You can also specify SNMP stations that are to receive traps from the
switch.
