DESCRIPTION
Specify the user name of a login account on the Switch. You can enter up to 32 printable
ASCII characters.
Select whether you want to implement authentication and/or encryption for SNMP
communication from this user. Choose:
•
no auth – to use the user name 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 printable ASCII characters (except [ ? ], [ | ], [ ' ], [ " ], [ space ],
or [ , ]) 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.
Enter the password of up to 32 printable ASCII characters (except [ ? ], [ | ], [ ' ], [ " ], [ space ],
or [ , ]) for encrypting SNMP packets.
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.
read-write – 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.
read-only – Members of this group have read rights only, meaning the user can collect
information from the Switch.
Click Apply to 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.
Click Clear to clear the fields to the factory defaults.
Click Cancel to not save the configuration you make and return to the last screen.
