Can't get Remote port mirroring to work

[Kilgore]

Hi, I have configured remote port mirroring from 1 5400zl to another, using instructions here:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02640590/c02640590.pdf

I have tried using both PCM+ and the CLI, and neither works.  The PCM+ method doesn't change the switch configuration at all (or sometimes just hangs and fails) and the CLI method looks like it's configured correctly, but when I look at traffic with my analyzer, I only see broadcast traffic.

I've tried to do this multiple times on multiple switches, but can't make it work.  Is there another way?

Thanks for the help!

Are you sure your Source port has "monitor all both" on it?

Yes, definitely.  Does invoking the same command more than once have a negative effect?
