DESCRIPTION
Note: Use the username and password of the login accounts you specify in this screen to
create accounts on the SNMP v3 manager.
Specify the username of a login account on the Switch.
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.
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.
Enter the password of up to 32 ASCII characters for SNMP user authentication.
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.
