[j-nsp] DSCP classifier on CCC interface

[Serge Vautour]

Hello,

I was testing this on a DPC card in an MX960. That link helps. It's not the news I wanted to hear but it helps.

Thanks,
Serge

Serge:

What platform/line-card are you trying this on?  This is possible in JUNOS
11.4 when using Trio/MPC line-cards on the MX.  See 11.4 release notes:
