error disabled port status

Quick question, I'm just curious if there is a way to disable the port status 'error disabled' on a port.  For instance, is there a way to make it to where the ports can't go into that status.  That would be cool, but I don't think you can disable a port feature like that on the 3500 series.  Let me know, thanks!

    Why would you want to do that?  That is your signal that something is wrong with either your cable, the device on the other end, or your switch.  That's something that needs to be investigated!

    I suppose it depends on the REASON it went to err-disable.  But I'd agree with the "why would you want to?" question raised already. 

     

    You can use "errdisable recovery" commands to have your switch automatically re-enable a port after 'x' number of seconds, but that doesn't avoid things entirely.

     

    So let's go back to "what are you really trying to accomplish?"

    Hi!

     

    I work in the IT field as a network administrator for a hospital so I am in the medical industry as well.  I have a couple of questions.

     

    1)  Why do your "not so smart" medical staff have access to your physical infrastructure.  Can you say security risk?

     

    2) With regards to question number one, Wouldn't that be a HIPAA violation?

     

    I would look into getting your infrastructure secured so that medical staff do not have access to your switches.

    Rickey, second sentance in that post explained it all.   Any specific reason why this switch is accessible to end users?

    Hi!

     

    Does the medical equipment have wireless capability or can they use a wall jack to connect to the network?  I am not familiar with your layout or anything, but even still, that sounds very insecure and deserves some consideration to alternate solutions.

    It's not just "Not for Profit" hospitals that don't spend money. <cough cough>

    Check this link out: http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a00806cd87b.shtml

     

    You can probably grab that header and search and come up with a better document.  You can also search for configuration guides for those specific IOS revisions and it will explain.  However, this seems simple enough that you can just enter config t, type in "errdisable ?" and you'll see what needs to be done.

    Yup, as noted above, you want to setup your err-desable cause and interval appropriately!   That way you won't despise your users so much!

     

    Always remember though, the more idiot-proof you make something, they'll just keep coming up with better idiots!
