accessing 2950t-48-si with CNA

When I try to access the switch with CNA 5.1, I enter the IP address of the switch, and I click connect, I get an error unable to connect. I open up options the protocol is http, the http port is 80 and the access mode is read write. I can access the switch with telnet. I have taken over this switch from somebody else. Is there a way I can tell which port I should be accessing instead of http 80.

thanks in advance

please post here your cisco config
On the switch you need to enable http unless you want to do it over https.

Switch#config t
Switch(config)#Ip http server ("Ip http secure-server" for https)
Switch#wr mem

Hope this helps
