Username Specify the username of a login account on the Switch.
Security Level Select whether you want to implement authentication and/or encryption for SNMP
communication from this user. Choose:
•
no a uth
equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest security
level.
•

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
encryption. It applies a 56-bit key to each 64-bit block of data.
•
AES
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
