### Description

```asn1
bfdSessAuthenticationType OBJECT-TYPE
SYNTAX IANAbfdSessAuthenticationTypeTC
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The authentication type used for this BFD session.
This field is valid only when the Authentication
Present bit is set. MAX-ACCESS to this object as well as
other authentication-related objects are set to
read-create in order to support management of a single
key ID at a time; key rotation is not handled. Key update
in practice must be done by atomic update using a set
containing all affected objects in the same varBindList
or otherwise risk the session dropping."
REFERENCE
"Sections 4.2 - 4.4 of RFC 5880, Bidirectional Forwarding
Detection (BFD)."
DEFVAL { noAuthentication }
