| * [[sortedstats|Traffic statistics]] (2,20) for all "intersections" in the network; i.e. all router and switch ports. Octet, packet and error counters are collected, along with CPU and memory statistics, temperature sensors (and more). Use the [[sortedstats#ranked_statistics|"ranked statistics"]] (19) to present a list of interfaces with most traffic, the highest error counts, etc. The traffic statistics collection uses [[http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/|RRDTool]] and [[http://cricket.sourceforge.net/|Cricket]].

| * What type of network equipment do we have in our network? What kind of switches and routers, how many of each, where are they located? What software and hardware versions are they running? How many modules are there in the various stacked and chassis based switches? Are there any free, or almost free, modules? Help me get the overall picture, I need to expand switch Z and are looking for spare parts... | * What type of network equipment do we have in our network?
