iawells / dc-check

Overview

This emulates a DC checker.

The real program would log into switches in a rack, identify attached server management ports, log into the servers, check the connectivity between servers and switches, and report this on a REST interface as JSON objects.

This program reads a YAML description of a rack or racks and emulates what an SDN controller might tell you about the devices concerned.

TODO: will report that servers are connected to TORs and other servers even when those servers are not under management. Given you couldn't put LLDP on those servers without a management connection, that's unlikely to be true in reality.

TODO: assumes the TORs don't use the management switch in the rack. That one is a 'maybe' - depends on the network engineer's preferences.

TODO: very little sunny-day testing, including none of the REST endpoints. Should have tests to ensure that more than the valid.yaml test file actually works.
