Abstract

We present the design and implementation of Splat, a tool for managing network edge switch ports and port-to-host configurations. We discuss the need for such a tool as part of a major network upgrade, and our discovery that most existing tools ignore this area or approach it from a core network point of view.

Important design considerations include the current procedures and habits of our system administration team, using open source components, and the tool's incremental development and deployment. In particular, the requirement for accurate configuration information in a database proves to be an effective means of enforcing correct procedures.

Splat enables us to administer an increasingly complex network by providing a simple interface for routine tasks as well as better diagnostics, reporting, and monitoring. Its reliable configuration management enhances the security and performance of our network.
