I am new Perl, Please be patient with me
I would like to write perl script that need to do:
1) Discover all Cisco Switches on the Network not other devices
2) Query all the cisco switches found in 1) and see how many connected port are 10Mbps, how many are 100Mbps and how many are Gigabit
3) Generate a report that show:
Switch name 10Mbps 100Mbps 1Gbps

    I'm newbie too. 1)I don't know how to discover.I think you must get a seed device at least.Then you can get any other switch or router which connected to this switch via cdp. 2)It can be done by net::snmp,you can do it by get status of the interface via oid.

    Net::SNMP is probably a good place to start. If you search CPAN for 'Cisco' you will find lots of stuff.

    nmap does it. But if you need a custom solution you can run many ways. I'll give you two of them

    If you already know the address of the Cisco devices, just point nmap to them, get its output (e.g., the XML one) and parse it with one of the many perl modules around (e.g.: XML::Twig)

    If you don't know the addresses, well, scan the whole network, get an XML output, select the cisco devices and work on them

    You could also generate a report directly from the NMAP XML output using, for example, XML::XPathScript.

    Good luck!

    The very nature of Perl to be like natural language--inconsistant and full of dwim and special cases--makes it impossible to know it all without simply memorizing the documentation (which is not complete or totally correct anyway).

    You might also want to invest in the book Network Programming With Perl by Lincoln Stein. There's all sorts of good example code (with great explanations) that should give you ideas about how to proceed.
