[j-nsp] CoS Marking/Rewrite Theory - Update!

[Mark Tinka]

So this is a very old thread (from nearly two years back):

nsp at puck.nether.net/msg04181.html

Looks like Juniper now provide support for ingress ToS 
remarking/rewriting, much like Cisco do. This is as opposed 
to the regular way it's done in JUNOS, which is rewriting on 
egress.

This capability is supported in the Translation tables 
mechanism:

products/topic-collections/config-guide-cos/topic-27854.html

Big problem, however: this feature is only supported on IQ2, 
IQ2E and the Trio line cards (including the MX80). Sadly, 
not even the DPC-E-Q-R on the MX240/480/960 is supported. 
Beats my understanding, but...

So we're pretty much there, especially if you're a new 
Juniper user :-).

Cheers,

Mark.
