This is an interactive configuration editor for Cisco devices. It is based on joe editor's macros that let you load either running or startup configuration from a Cisco router/switch/access server directly into the editor and commit it back after modification. The CiscoConf program maintains the database of previous versions of startup and running configurations for each router in /var/db/CiscoConf. The number of versions to keep is specified in its configuration file. It also provides locking to prevent concurrent editing of the same configuration by more than one person.
