  1. Configuration Best Common Practices snmpconf - IETF 47 March 30, 2000 Michael R. MacFaden mrm@riverstonenet.com snmpconf wg -- ietf 47

  2. Presentation Topics • Review BCP Draft Outline • Solicit contributions • draft-ietf-snmpconf-bcp-00.txt snmpconf wg -- ietf 47

  3. Goals of BCP • Document existing knowledge and techniques which demonstrate effective use of the SNMP Framework for device specific and policy based configuration • Recommendations based on: • actual implementation experience • actual deployment experience snmpconf wg -- ietf 47

  4. Tasks • April • Collection of information and best current practices on the snmpconf mailing list. • Produce new draft for upcoming May meeting • May • Revise based on feedback compiled for 17-19 May • June 28, 29, 30 • Revise based on May meetings and further development • July 14 • Publish revised Internet Draft • Aug 2000 • 48th IETF meeting in Pittsburgh snmpconf wg -- ietf 47

  5. BCP Outline • Major areas • Tenets of Configuration • Terminology • MIB Design Principles • Management System Design • Policy Related Topics snmpconf wg -- ietf 47

  6. Tenets • A loss of connectivity can occur at any time • “Mere Mortal” constraint • Side effects of changes should be explicit • “Walk softly” constraint • Minimizing lost convergence due to configuration changes snmpconf wg -- ietf 47

  7. MIB Design • Selecting a correct abstraction • Metrics include: • Number of managed objects • Rate of change • Latency in set operations • Latency in get operations • Reporting configuration level errors snmpconf wg -- ietf 47

  8. MIB Design • Diagnostics support • Notifications • Scaling up to massive configurations • 1000s of Access Control lists • Persistence • Multiple Management Interfaces • Multiple Managers snmpconf wg -- ietf 47

  9. Management System Design • Best current practices on manager side • What a given agent is capable of • Use of Agent capabilities and examples • How a manager would use sysORTable • Alarm and fault integration • Configuration accounts for a majority of service outages • Coordinating configuration changes with Fault Mgmt snmpconf wg -- ietf 47

  10. Policy Related • MIB machinery that provides • discovery of Policy types and sub types • Role definition and distribution • Capability collection and usage • Policy definition and distribution snmpconf wg -- ietf 47
