show spanning vlan 50. It shows an interface named "st5" which is blocked.

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.
