LABEL DESCRIPTION
Authentication Protocol
Select whether you wish to implement password authentication for SNMP
communication with the managed device. 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.
If you select MD5 or SHA, enter a password between 8 and 100 ASCII characters for
SNMP user authentication.
Privacy Protocol
Select whether you want to implement encryption for SNMP communication with
the managed device.
• 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• AES - Advanced Encryption Standard superseded DES as the data encryption
standard and also uses a secret key. AES applies a 128-bit key to each 128-bit
block of data.
If you select DES or AES, enter the password of between 8 and 100 ASCII characters
for encrypting SNMP packets.
