LABEL	DESCRIPTION
Authentication	Select an authentication algorithm. MD5 (Message Digest 5) and SHA (Secure Hash
	Algorithm) are hash algorithms used to authenticate SNMP data. SHA authentication is
	generally considered stronger than MD5, but is slower.
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 encryption for
Level	SNMP communication with this user.
Authenticati	This field displays the authentication algorithm used for SNMP communication with this
on	user.
Privacy	This field displays the encryption method used for SNMP communication with this user.
Group	This field displays the SNMP group to which this user belongs.
Delete	Click Delete to remove the selected entry from the summary table.
Cancel	Click Cancel to begin configuring this screen afresh.

38.4 Setting Up Login Accounts

Up to five people (one administrator and four non-administrators) may access the Switch via web configurator at any one time.

•An administrator is someone who can both view and configure Switch changes. The username for the Administrator is always admin. The default administrator password is 1234.
