LOL - I just re-read my post... to clarify - I can not ping it, but I can console to it... And none of the VTYs are in use. In fact, when I'm consoled into the device it can telnet itself just fine! Really bizarre...

I'd reset the mask on the sc0 int (regardless of what it shows in the config) assuming you can't telnet to it from a workstation attached to the 4k (if you can it sounds like a native mismatch on your trunk). I saw this once on a 2948 at a remote location, it went weeks passing traffic o.k. but I couldn't telnet or ping until it could be rebooted. - Original Message - From: "Stevo" To: Sent: Wednesday, July 23, 2003 4:05 PM Subject: Re: Cat 4000 Connectivity Issues!

Are you sure you don't have a duplicate address or fualty addressing somewhere??

This is reminiscent of the following vulnerability: http://www.cisco.com/warp/public/707/cisco-sa-20030709-swtcp.shtml However, Stevo is running IOS, not CatOS. I wonder if there's a similar problem with Cat4K IOS? John >>> MADMAN 7/24/03 10:11:26 AM >>> Are you sure you don't have a duplicate address or fualty addressing somewhere??
