You do not see the STP bpdu on the monitor traffic because it never goes through the RE kernel.
It is transmitted directly from the PFE periodically.
You can check this from show ppm transmissions detail.

Hi.
Using 'monitor traffic ...', I cannot capture transmitted BPDUs on a device, only received BPDUs.
Why is that?
Thanks,
