The line is:
<br />St5 Back BLK 100 128.876 P2p
<br />
<br />What is this st5 interface? I can guess that it's about stack5. However what does it mean exactly?
<br />
<br />I am using a stack of 5 Cisco 3750 switches.
<br />
<br />Thanks!

Yes, it's stack port but I am not sure how it is numbered.
To my knowledge, it should not be displayed in "show spanning" unless debug spanning is enabled.
If not and your switch running a old code, it might be a bug.
