Configuring the SHA Authentication

To configure the secure hash algorithm (SHA) as the authentication type for an SNMPv3 user, include the authentication-sha statement at the [edit snmp v3 usm local-engine user username] hierarchy level:

[edit snmp v3 usm local-engine user username] 

authentication-sha {

    authentication-password authentication-password;

}

authentication-password is the password used to generate the key used for authentication.

SNMPv3 has special requirements when you create plain-text passwords on a routing platform:

• The password must be at least 8 characters long.
• You can include most character classes in a password (alphabetic, numeric, and special characters), except control characters.
