Sounds to me like you have 2 possible angles to attack this problem:
  • use SNMP to query the switches to see which IP is on which port. Its been a long time since I've written an SNMP poll for a switch, but if I remmember right I think the info you want is in the Bridge MIB.
  • The static IP's should be pretty easy to locate. For the dynamics you could query the DHCP server(s) to see what MAC a particular IP is assigned to. This may or may not be doable (and may or may ont be doable via SNMP), it depends on the capability of your DHCP server.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
