Changing the Default Values of SNMP Community Strings
The controller has commonly known default values of “public” and “private” for the read-only and
read-write SNMP community strings. Using these standard values presents a security risk. If you use the
default community names, and since these are known, the community names could be used to
communicate to the controller using the SNMP protocol. Therefore, we strongly advise that you change
these values.
Using the GUI to Change the SNMP Community String Default Values
To change the SNMP community string default values using the controller GUI, follow these steps:
Step 1 Choose Management and then Communities under SNMP. The SNMP v1 / v2c Community page
appears (see Figure 4-15).
