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.
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 this to create a new entry or to update an existing one.
This saves 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 Level
This field displays whether you want to implement authentication and/or encryption for SNMP
communication with this user.
Authentication This field displays the authentication algorithm used for SNMP communication with this 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.
Select an entry’s check box to select a specific entry. Otherwise, select the check box in the
table heading row to select all entries.
Delete
Click
Delete
to remove the selected entry from the summary table.
