The following table describes the labels in this screen. 

Apply

to save your changes to the non-volatile memory when you are done configuring.

Cancel

Click Cancel to begin configuring this screen afresh.

Security Level

Select whether you want to implement authentication and/or encryption for SNMP 
communication from this user. Choose:

•

noauth -to use the username as the password string to send to the SNMP manager. 

This is equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest 

security level.

•

auth - to implement an authentication algorithm for SNMP messages sent by this user.

•

priv - to implement authentication and encryption for SNMP messages sent by this 

user. This is the highest security level.

Note: The settings on the SNMP manager must be set at the same security level or higher 

than the security level settings on the Switch.
