[j-nsp] Question about 100 Gbps MPC4E

Fri Feb 6 12:18:49 EST 2015

Paul, we didnt do this test.

We can do it ...

But we will need to run in ae5, because the traffic is very high today 90
Gbps and will rise a lot for the next few months.

The junos version is 13.3R2.

Do you think that ae5 configuration is not helping ?

We did the same test, on the same box, with 12 x 10G SFPP (MPC4E) and it
works fine.

Thanks a lot,

Giuliano
