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 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.
