There are two commands (undocumented even in 12.0):
'show int switching' <---switching MUST BE SPELLED OUT 'show int s' <---provides a summary form of the above
If the latter is an abbreviation for something, I don't know what it is.
The "s" in your second command is short for stats. It doesn't look like this command is referenced in cisco's IOS Essentials doc that was mentioned earlier. That just shows the 'show interface switching' command. routerA#show interface stats FastEthernet0/1/0 Switching path Pkts In Chars In Pkts Out Chars Out Processor 207745 14075132 270885 21915788 Route cache 0 0 0 0 Distributed cache 93 9729 0 0 Total 207838 14084861 270885 21915788 Jamie Byrne
