Cisco Cisco 4402 Wireless LAN Controller

In the remaining fields, enter the IP address from which this device accepts SNMP packets with the 
associated community and the IP mask, choose Read Only or Read/Write to specify the access level 
for this community, and choose Enable or Disable to specify the status of this community.

Click Apply to commit your changes.

Click Save Configuration to save your settings.

Repeat this procedure if a “public” or “private” community still appears on the SNMP v1 / v2c 
Community page.

Follow these steps to change the SNMP community string default values through the controller CLI.

To see the current list of SNMP communities for this controller, enter this command:

If “public” or “private” appears in the SNMP Community Name column, enter this command to delete 
this community:

config snmp community delete name

The name parameter is the community name (in this case, “public” or “private”).

To create a new community, enter this command:

config snmp community create name

Enter up to 16 alphanumeric characters for the name parameter. Do not enter “public” or “private.”

To enter the IP address from which this device accepts SNMP packets with the associated community, 
enter this command:

config snmp community ipaddr ip_address ip_mask name

To specify the access level for this community, enter this command, where ro is read-only mode and rw 
is read/write mode:

config snmp community accessmode {ro | rw} name

To enable or disable this SNMP community, enter this command:

config snmp community mode {enable | disable} name

To save your changes, enter save config.

Repeat this procedure if you still need to change the default values for a “public” or “private” community 
string.

The controller uses a default value of “default” for the username, authentication password, and privacy 
password for SNMP v3 users. Using these standard values presents a security risk. Therefore, Cisco 
strongly advises that you change these values.
