Hello, My customer grew from a small enterprise to an SP/Mobile operator network very quickly. I want to guide them on how to operate their network, so I am looking for a document for this. On the top of my head and please add your suggestions: 1) Change Management 2) Network Management 3) Daily Operational tasks/process Let me explain what's on my mind for each point above: 1) I can think of RANCID and TACACS+ in terms of configurations, but they also do hardware changes that affects the network without any strict procedures (example: add a switch and start an STP loop) 2) This I can get, but would also welcome suggestions, NMS, SNMP, netflow…. 3) Ticketing system, escalation procedures, troubleshooting documents, backup procedures, inventory… Your valuable input would be highly appreciated,. Regards, Kim
