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.
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.

Click Cancel to reset the fields to your previous configuration.
Clear
Click Clear to reset the fields to the factory defaults.
