fw ctl zdebug drop in VSX

[C_M]

Can 

 fw ctl zdebug drop be ran from VS0 or does it have to be run in a certain policy such as vs1, vs2, etc. in VSX for it to work?

Pretty sure you'll need to specify the -vs flag for that to work properly, as each VS has separate fwk kernel processes.  I don't think running it in VS 0 without the -vs option will catch drops in the other VSs, although this SK would seem to suggest otherwise: sk167412: Using 'fw ctl zdebug' or FW Monitor on VSX Fails Because of Memory or Buffer Issues

Thanks.

In versions backed by VRFs (R80.30 and earlier; kernel 2.6.18), it can be run from any VS, and it shows drops from all VSs at the same time. Each drop is prefixed to indicate which VS it comes from. For example, "[vs_27]" for a drop in context 27. I believe it can be run as 'fw -vs <vsid> ctl zdebug drop' to run in one VS, but I've never had to try that.

I haven't worked much with VSX backed by network namespaces (R80.40 and up; kernel 3.10) yet, so I don't know if it's different there.
