I've got a pile of switches connecting everything together at our DC, 50 racks or so worth of kit. It's starting to be a problem to login to every single one of them to make configuration changes -- mostly adding/removing VLANs to all the trunk ports, but every once in a while there's some other config change we need to rollout to all the switches.
Is there anything out there of a Linux/FOSS nature to push switch configs en masse? I've looked at RANCID, and while it looks awesome for what it does (retrieving configs and reporting on changes), if it supports modifying configs centrally and rolling them out, it's hiding that light under a bushel.
