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. Therefore,
Cisco strongly advises that you change these values.
Using the GUI to Change the SNMP Community String Default Values
Follow these steps to change the SNMP community string default values through the controller GUI.
Click Management and then Communities under SNMP. The SNMP v1 / v2c Community page appears
Step 1
(see
Ol-9141-03
This command behaves like an SNMP access list. It specifies the IP address from which the
device accepts SNMP packets with the associated community. The requesting entity's IP address
is ANDed with the subnet mask before being compared to the IP address. If the subnet mask is
set to 0.0.0.0, an IP address of 0.0.0.0 matches to all IP addresses. The default value is 0.0.0.0.
The controller can use only one IP address range to manage an SNMP community.
