[Mengal]

Dear all Members !

                                  Last weak I configured 3com 7906E core switch in my organization.

 When I set the "authentication mode scheme" & password ************** now I am trying to login in my 3com7906E core Switch. it asks user name: & Password :

By the way I forget to create local user. Now I am going to try to login it is login faild. Anyone can help me the default facutry password & user name. Or tell me How I can reset saved configurations in 7906E through telnet or other way without login ID & password.

Your support will be appriaciate.

Best Regards !
