[c-nsp] 7206vxr w/g1 question.

[Marcus.Gerdon]

Hi Keith,

as you're running a 7206VXR with NPE-G1 I assume the 3 other GigE you mention are the onboard ones. Also 4/0 has to be a PA-GE if there's no newer PA available I've missed.

As far as I remember a 7200VXR is 600 bandwidth points per bus, not 400.

But I think there's been something about an PA-GE delivering max. ~200mbit/s which you are quite close at. I suppose that's the bottleneck you're experiencing.

If one of the onboard GigE has sufficiently low traffic try swapping 4/0 with 0/x for a test.


regards,

Marcus
