HTML Output on Console

I'm having an odd issue with a Catalyst 6513 and its http interface. The http interface has been working just fine in the past, however it just times out now in the browser. Now here is the interesting part. If I'm logged onto the switch console when I try to browse to it, I get the following http segment echoed on the console:

HTTP/1.0 401 Unauthorized

Date: Wed, 17 Jun 2009 13:20:30 GMT

Content-type: text/html

Expires: Thu, 16 Feb 1989 00:00:00 GMT

WWW-Authenticate: Basic realm="access"

<HEAD><TITLE>Authorization Required</TITLE></HEAD><BODY BGCOLOR=#FFFFFF><H1>Authorization Required</H1>Browser not authentication-capable or authentication failed.</BODY>

This seems to me to be really odd behavior and I was wondering if anyone else had ever seen it before.

I have already disabled and enabled the http server to no avail. I'm getting ready to fail the supervisor over to see if that clears it up, but I would rather not have the seconds of down time (it's our core network switch) if I can help it.

Any information anyone has about this will be greatly appreciated.

Hello Chris,

this looks like to be some form of SW defect it shouldn't send http message on the console/vty output but on the correct TCP socket.

Hope to help

That's what I'm thinking too. I have decided to go ahead and upgrade the switch to the newest version of CatOS to see if that would help fix the issue.
