Configure SNMPv3 Authentication Type and Encryption Type

Configure SNMPv3 Authentication Type

By default, in a Junos OS configuration the SNMPv3 authentication type is set to none.

This topic includes the following sections:

Configur MD5 Authentication

To configure the message digest algorithm (MD5) as the authentication type for an SNMPv3 user, include the authentication-md5 statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see authentication-md5.

Configure SHA Authentication

You can configure the following secure hash algorithm (SHA) as the authentication type for an SNMPv3 user:

  • authentication-sha

  • authentication-sha224

  • authentication-sha256

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. For more information about this statement, see authentication-sha.

To configure the secure hash algorithm (SHA) as the authentication type for an SNMPv3 user, include the authentication-sha224 at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see authentication-sha224.

To configure the secure hash algorithm (SHA) as the authentication type for an SNMPv3 user, include the authentication-sha256 statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see authentication-sha256.

Configure No Authentication

To configure no authentication for an SNMPv3 user, include the authentication-none statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see authentication-none.

Configure SNMPv3 Encryption Type

By default, encryption is set to none.

Before you configure encryption, you must configure MD5 or SHA authentication.

This topic includes the following sections:

Configure Advanced Encryption Standard Algorithm

To configure the Advanced Encryption Standard (AES) algorithm for an SNMPv3 user, include the privacy-aes128 statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see privacy-aes128.

Configure Data Encryption Algorithm

To configure the data encryption algorithm (DES) for an SNMPv3 user, include the privacy-des statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see privacy-des.

Configure Triple DES

To configure triple DES for an SNMPv3 user, include the privacy-3des statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see privacy-3des.

Configure No Encryption

To configure no encryption for an SNMPv3 user, include the privacy-none statement at the [edit snmp v3 usm local-engine user username] hierarchy level. For more information about this statement, see privacy-none.
