no switchport % incompleted command Cisco 2950 switch

Hi

  It seems that you have a layer 2 switch in hands,  which is expected for this switch model. 

 But, with apropriate licesing you can possibly use it as layer 3 device. 

 However, you need IP service license. You can check with "show version" if it shows 

 Lan base or IP base, you ned to change the license to IP sercvice. 

 The problem is that this switch is probably end of everything, so,  chances are you can not fix this.
