Hi,

<whine mode: on>

Why oh why, in the name of the gods of Junos, is mirror/analyse done
before DSCP rewrite?
(aka why oh why is DSCP rewrite done on egress?)

..there's probably a really good architectural reason but jeez, it
doesn't help when you have some brain-dead endpoints that can't make
their own traffic and your network performance probe (attached to the
same switch) reports on packet marking/QoS.

cheers :)
