Your image does not support snooping looking at the feature navigator

as well that image is so old its not even listed anymore with cisco its deferred state by the look of it , the only image left in that train is 12.4 19a to donwload , all other images you cant support as you don't have enough ram only 128 , all new images are 192 or more up to 256

19a does not support snooping either way to old , you need more ram and move to a newer image that supports snooping , you can check on the feature navigator below
