Please paste the configuration of the switch.

Your 2950 is a layer 2 switch and you can have only one Vlan interface ( SVI-Layer3 which is used to manage the switch only ) up at any given time. Make sure that your PC is in the same vlan interface which you have given the IP. For example..

if your int vlan 1 is up and have any ip on it.. your PC should be in the same vlan to communicate with the switch for upgrade the IOS.

HTH,

As per the config you PC is in Vlan vlan make sure that it is in the same vlan.Please check for any Personal firewall on your PC. If its is Windows XP it has a bulit in firewall,please disable that. If you have any other firewall on your system like symantec, norton etc. disable it.

Did you check all the physical layer part/connectivity.

Please paste the output of "Show int Vlan 1".

Please paste the output of the "show interface fa x/y " of the interface where your PC is connected.

Hello...

Check the interface Ip ...

Internet address is 200.200.202.1/24 <<<---

Its showing something different to what you earlier pasted. Check the Ip addressing again on your Vlan interface and the Host PC.

I guess you have wrongly entered the IP addresses on either of these device. Check it again and also the firewall part. If you correct your Ip addresses and still you are unable to ping then it is definetly something to do with the software firewall, or any other software which is not letting the traffic pass through.

HTH, Please rate if it does.
