Using the CLI to Change the SNMP v3 User Default Values

Follow these steps to change the SNMP v3 user default values through the controller CLI.
Step 1 To see the current list of SNMP v3 users for this controller, enter this command:
show snmpv3user
Step 2 If "default" appears in the SNMP v3 User Name column, enter this command to delete this user:
config snmp v3user delete username
The username parameter is the SNMP v3 username (in this case, "default").
To create a new SNMP v3 user, enter this command:
Step 3
config snmp v3user create username {ro | rw} {none | hmacmd5 | hmacsha} {none | des | aescfb128}
auth_key encrypt_key

Step 5 To reboot the controller so that the SNMP v3 user that you added takes effect, enter reset system.

Configuring Aggressive Load Balancing

Enabling aggressive load balancing on the controller allows lightweight access points to load balance
wireless clients across access points. You can enable aggressive load balancing using the controller GUI
or CLI.
When a wireless client attempts to associate to a lightweight access point, association response packets
are sent to the client with an 802.11 response packet including status code 17. This code indicates that
the access point is too busy to accept any more associations. The client then attempts to associate to a
different access point. For example, if load balancing is enabled and the client count is configured as 5
clients, when a sixth client tries to associate to the access point, the client receives an 802.11 response
packet with status code 17, indicating that the access point is busy.
OL-17037-01
username is the SNMP v3 username;
ro is read-only mode and rw is read-write mode;
none, hmacmd5, and hmacsha are the authentication protocol options;
none, des, and aescfb128 are the privacy protocol options;
auth_key is the authentication shared secret key; and
encrypt_key is the encryption shared secret key.
