I have two dell PC switches, a 3348 and a 3548.

In the past, I have been able to admininster either switch via http.

Right now, I can only administer the 3548 via http, I can administer either switch via telnet.

I have tried ie and firefox, same result. I have tried several client computers. Same result. I have tried plugging the clients into each switch, same result.

The switches are on the same subnet. No VLANs are defined. Using telnet I have "show" all the things that I can think of and both switches appear to be configured similarly.  IP Addr, of the 3348 is 192.168.11.2, IP Addr of the 3548 is 192.168.3, the IP of the gateway is 192.168.11.1.

The message from ie is:

Internet Explorer cannot display the webpage

The option to "diagnose" is offerd.

The results of diagnose are: No problem detected, try refresh

ie is actually talking to the switch, it just does not like what it sees.

If neccessary, I can write a script to poll the switch to determine why the response is not valid http, but if some one knows of a configuration issue that manifests this way it would save some time.
