Description:
Additional functionality to automate Cisco management
Net::Telnet::Cisco provides additional functionality to Net::Telnet for dealing with Cisco routers. It provides a new object that allows for remote management of routers through perl issuing commands like you were connected directly to the router (or switch). . For most management issues you might want to use the Net::SNMP module better (it's faster, better error handling and doesn't use up router virtual terminals) but for those things you can not do using that module use this one.
