User's Manual Part 1

Chapter 3: System planning Security planning
Identify the security level for each of the security roles. Three security levels are available: (a) No
authentication, no privacy; (b) Authentication, no privacy; (c) Authentication, privacy.
If authentication is required, identify the protocol. Two authentication protocols are available: MD5
or SHA.
If privacy will be used, identify the protocol. Two privacy protocols are available: DES or AES (an
AES 128-bit or 256-bit capability upgrade must be purchased).
If authentication or authentication and privacy protocols are required, identify passphrases for
each protocol for each SNMP user. It is considered good practice to use different passphrases for
authentication and privacy. Passphrases must have length between 8 and 32 characters, and may
contain any of the characters listed in Table 36.
