Unfortunately, switchport block {multicast | unicast} is only supported on the "EI" switches:  Catalyst 2950G-12-EI, 2950G-24-EI, 2950G-24-EI-DC, 2950G-48-EI, and 2955 switches running Cisco IOS Release 12.1(19)EA1 or later.

  All 2950's run the same exact software but the software is smart enough to know what model it is being installed on and unless you have a model that supports EI services there is no way to change that  .  If your model currently has standard services on it thats all it will run . A show version will tell you what model and version you have.

  Don't think that image will work too well seeing its for a 3750 ...  He would need to post a show version to see if the 2950 is a SI or a EI switch , if its SI then there is nothing he can do .
