check hostname (in addition to IP address) for 'already done'.Avoid discovering same router twice if redundant paths

I had initally given some thought to the fact that many routers may get discovered multiple times, because they by their nature have multiple IPs.

The problem I have with checking by hostname is that it is entirely possible to have multiple devices with the same hostname, (ok - I guess using IPs reserved for private networks it would be possible to have the same IP on multiple devices, but the box you're running the script off of wouldn't be able to have a route to more than one of them at a time).

I am considering using serial numbers as my second key to verify uniqueness, however the OID for serial numbers appears to vary from device to device.

Checking the serial number would still entail opening an SNMP session, but at least your output would be a little less redundant.

Well off I go to find more usefull OIDs ...

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).
