RANCID (Really Awesome New Cisco confIg Differ) collects a router's (or device's) configuration, including software and hardware (cards, serial numbers, etc.), and uses CVS to display differences from a previous collection. It supports Cisco routers, Juniper routers, Catalyst switches, Foundry switches, Redback NASs, and ADC EZT3 muxes. The Beta version currently includes support for Bay Networks (nortel) routers and Extreme switches. Rancid also includes a lookingglass and the device login scripts may be used to automate a number of tasks.
Cisco Template Manager (CTM) is a set of tools that make it easy to manage Cisco configurations over a whole network based on your self-defined templates. With CTM you will have a unified configuration in your entire network, which is the basic building block of operational stability and security. The pre-defined templates support regular expressions. It supports the C760x, C730x, C37xx, C35xx, C29xx, C28xx, C18xx, and C17xx family series.
Symbolic is an enterprise platform designed to build, configure, and manage your huge and globally distributed data centers. It features cloud computing, Web manager virtual environments (Xen, KVM, and libvirt), clustering support, custom operations and scripts support, and user and role definitions.
Netomata Config Generator (NCG) creates complete, ready-to-install configuration files for network devices and services from a common lightweight model of a network. Because these configuration files are generated programmatically and generated from a shared model, they are more likely to be consistent and complete, making a network more reliable, easier to troubleshoot, and easier to expand in both size and functionality. The inputs to NCG are a model describing the network and templates for the configuration files of the various devices (routers, switches, load balancers, firewalls, etc.) and services (SNMP, DNS, DHCP, etc.). From these inputs, NCG produces complete, consistent, ready-to-install configuration files for those devices and services.
netcf is a library and command line tool for configuring networking on Linux machines in a platform-independent way, using the platforms native configuration mechanisms. Supported are all the various ways in which physical interfaces, bridges, bonds, and VLANs can be combined. The configuration of a network connection is described in an XML format that emphasizes the logical relationship between the interfaces involved, e.g. a bridge connection describes the bridge interface itself and all the interfaces initially enslaved to it. Interoperability with existing network configuration tools is guaranteed since netcf relies only on native network configuration files, both for reading and writing them. Modifying network configuration with netcf has exactly the same effect as modifying the native configuration files directly, and netcf and other tools can be used interchangeably.
