[j-nsp] MX80 Input Scheduling/Shaping

[Alexander Arseniev]

Hello,

Ingress scheduling is supported only on Q and EQ MPCs - Juniper MX 
series book, 2nd ed, page 598.

MX80 COS capabilities are roughly equal to MPC1, without Q.

Thx

Alex

I have the 'traffic-manager mode ingress-and-egress' configured for the PIC and the following configured as a test in the CoS interfaces stanza:
