CCNP - TSHOOT - Maintenance Models

The main models used in assisting with the maintenance of a network are as follows:

1. FCAPS - which is - Fault mgmt, Configuration mgmt, Accounting mgmt, Performance mgmt and Security mgmt. Defined by ISO (International Organisation for Standardisation).
2. ITIL - the IT Infrastructure Library, which is a collection of best practices. When implementing this PLEASE PLEASE PLEASE remember it is Best Practice not THE Practice. I've worked at companies who have idiots Service Delivery Mangers who think that to be 'compliant' they need to implement all of the guidelines regardless of how big the firm is or how suitable the process is to their enterprise </rant>
3. TMN - Telecommunications Management Network, the ITU-T's variant to FCAPS tailored to the telecommunications field.
4. Cisco Lifecycle Services - You should be familiar with this from your ROUTE and SWITCH studies Chpt1. Covering the PPDIOO - Prepare, Plan, Design, Implement, Operate, and Optimize life cycle.
