LABEL	DESCRIPTION
Password	Enter the password of up to 32 ASCII characters for SNMP user
	authentication.
Privacy	Specify the encryption method for SNMP communication from this user.
	You can choose one of the following:
	• DES - Data Encryption Standard is a widely used (but breakable)
	method of data encryption. It applies a 56-bit key to each 64-bit block
	of data.
	• AES - Advanced Encryption Standard is another method for data
	encryption that also uses a secret key. AES applies a 128-bit key to
	128-bit blocks of data.
Password	Enter the password of up to 32 ASCII characters for encrypting SNMP
	packets.
Group	SNMP v3 adopts the concept of View-based Access Control Model (VACM)
	group. SNMP managers in one group are assigned common access rights
	to MIBs. Specify in which SNMP group this user is.
	admin - Members of this group can perform all types of system
	configuration, including the management of administrator accounts.
	readwrite - Members of this group have read and write rights, meaning
	that the user can create and edit the MIBs on the Switch, except the user
	account and AAA configuration.
	readonly - Members of this group have read rights only, meaning the
	user can collect information from the Switch.
Add	Click Add to insert the entry in the summary table below and save your
	changes to the Switch’s run-time memory. The Switch loses these
	changes if it is turned off or loses power, so use the Save link on the top
	navigation panel to save your changes to the non-volatile memory when
	you are done configuring.
Cancel	Click Cancel to reset the fields to your previous configuration.
Clear	Click Clear to reset the fields to the factory defaults.
Index	This is a read-only number identifying a login account on the Switch.
	Click on an index number to view more details and edit an existing
	account.
Username	This field displays the username of a login account on the Switch.
Security	This field displays whether you want to implement authentication and/or
Level	encryption for SNMP communication with this user.

ion	communication with this user.
Privacy	This field displays the encryption method used for SNMP communication
	with this user.
