The will avoid to hard coding the 'device_type' when using the ConnectHandler factory function from Netmiko. Example: ------------------ from netmiko.snmp_autodetect import SNMPDetect my_snmp = SNMPDetect(hostname='1.1.1.70', user='pysnmp', auth_key='key1', encrypt_key='key2') device_type = my_snmp.autodetect() ------------------ autodetect will return None if no match. SNMPDetect class defaults to SNMPv3 Note, pysnmp is a required dependency for SNMPDetect and is intentionally not included in netmiko requirements. So installation of pysnmp might be required. � N)�cmdgenz=pysnmp not installed; please install it: 'pip install pysnmp')� CLASS_MAPPERz.1.3.6.1.2.1.1.1.0z.*Arista Networks EOS.*�c )�oid�expr�priorityz.*Palo Alto Networks.*z.*HP(E)?

Typically this will use the MIB-2 SysDescr and regular expressions. Parameters ---------- hostname: str The name or IP address of the hostname we want to guess the type snmp_version : str, optional ('v1', 'v2c' or 'v3') The SNMP version that is running on the device (default: 'v3') snmp_port : int, optional The UDP port on which SNMP is listening (default: 161) community : str, optional The SNMP read community when using SNMPv2 (default: None) user : str, optional The SNMPv3 user for authentication (default: '') auth_key : str, optional The SNMPv3 authentication key (default: '') encrypt_key : str, optional The SNMPv3 encryption key (default: '') auth_proto : str, optional ('des', '3des', 'aes128', 'aes192', 'aes256') The SNMPv3 authentication protocol (default: 'aes128') encrypt_proto : str, optional ('sha', 'md5') The SNMPv3 encryption protocol (default: 'sha') Attributes ---------- hostname: str The name or IP address of the device we want to guess the type snmp_version : str The SNMP version that is running on the device snmp_port : int The UDP port on which SNMP is listening community : str The SNMP read community when using SNMPv2 user : str The SNMPv3 user for authentication auth_key : str The SNMPv3 authentication key encrypt_key : str The SNMPv3 encryption key auth_proto : str The SNMPv3 authentication protocol encrypt_proto : str The SNMPv3 encryption protocol Methods ------- autodetect() Try to determine the device type. �v3� N� �sha�aes128c C s� |dks|dkr |s<t d��n |dkr4|s<t d��nt d��tjtjd�| _tjtjtjtjtj d�| _ || j� � vr�t d � | j� � ���| | j � � vr�t d � | j � � ���|| _ || _|| _|| _|| _|| _|| _| j| | _| j | | _i | _d S ) N�v1�v2cz*SNMP version v1/v2c community must be set.r z-SNMP version v3 user and password must be setz/SNMP version must be set to 'v1', 'v2c' or 'v3')r �md5)ZdesZ3desr Zaes192Zaes256z>SNMP V3 'auth_proto' argument must be one of the following: {}zASNMP V3 'encrypt_proto' argument must be one of the following: {})� ValueErrorr ZusmHMACSHAAuthProtocolZusmHMACMD5AuthProtocolZ_snmp_v3_authenticationZusmDESPrivProtocolZusm3DESEDEPrivProtocolZusmAesCfb128ProtocolZusmAesCfb192ProtocolZusmAesCfb256ProtocolZ_snmp_v3_encryption�keys�format�hostname� snmp_version� snmp_port� community�user�auth_key� encrypt_key� auth_proto� encryp_proto�_response_cache) �selfr r r r r r r r Z encrypt_proto� r# ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/netmiko/snmp_autodetect.py�__init__� sL ������ zSNMPDetect.__init__c C sz | j | jf}t�� }|jtj| j| j| j| j | j d�tj |ddd�|ddd�\}}}}|sv|d d rvt |d d �S d S ) aJ Try to send an SNMP GET operation using SNMPv3 for the specified OID.
