[j-nsp] CoS value of return traffic

[wojtas at wizja.net.pl]

Hello,
Is there a possibility to set the CoS (802.1p) value of return traffic  
from RE ?
I know that You can do it for, at least , DSCP using:
set class-of-service host-outbound traffic <dscp-code-point|forwarding-class)
Each time I send UDP echo probes to MX80 with different CoS values ,  
the router responds with the same pattern 100(binary). The best  
workaround in this case would be to set CoS values according to the  
particular DSCP (which is preserved in this case).
Thanks in advance for Your help!
