  1. Networked Device Management with SNMP SIA Working Group Presentation ASIS 2014 (Atlanta) SIA SNMP Working Group ASIS 2014

  2. Background • What is SNMP • IETF [3] protocol suite [1] for network management • Standards-based solution for managing devices on a network • Why use SNMP • Part of the expected feature set of modern civilized network-attached enterprise-class devices • Because you need the network before you can access the device • IOT: You need the internet before you can have the thing • SNMP history • First specified last century (RFC 1155 is from 1988) • IETF standard • Current state of the art is RFC 6353 (SNMP over TLS over TCP) SIA SNMP Working Group ASIS 2014

  3. SNMP Requirements • Follow the standards and styles of the SNMP implementor community including the common open source options • Support network management • definition of "network management" • Support management of the protocol stack • Support network management of the application and platform SIA SNMP Working Group ASIS 2014

  4. Example MIB Object SIA SNMP Working Group ASIS 2014

  5. SNMP Preferred Features • Accurate device identification • Support enough MIB objects to manage the device in question • MIB publically distributed • MIB “compilable” with standard tools • Secure access (TLS please?) SIA SNMP Working Group ASIS 2014

  6. SNMP MIB Compatibility SIA SNMP Working Group ASIS 2014

  7. Preferred SNMP - Details • Relevant MIB object groups • From RFC 1213: System, Interfaces, Address Translation, IP, ICMP, TCP, UDP, EGP, Transmission, SNMP • Multicast (RFC 5132) • PoE (example: CISCO-POE-PD-MIB-V1SMI [2]) • At least read access, preferably secure read/write SIA SNMP Working Group ASIS 2014

  8. How to Evaluate SNMP • Find the public copy of the MIB • Install the MIB in open source and commercial tools • Configure the device to support snmp as securely as possible • Walk the MIB collecting data • Validate the data is accurate • Exercise manipulation of the device through SNMP • Evaluate the implementation for security SIA SNMP Working Group ASIS 2014

  9. Terms • IETF • SNMP • MIB SIA SNMP Working Group ASIS 2014
