[c-nsp] NBAR & QoS

[Church, Charles]

We're using it on a 2821 for the same purpose - QOS to 2 upstreams, and
file sharing shaping.  Currently running about 10% CPU when pushing
about 9mb through it.  It's probably good for almost a full DS-3 on the
2821, at least in our application.  If you can run 12.4 on the NPE225,
I'd say enable it on a couple subints (protocol discovery) at a time,
and keep an eye on the cpu.  If CPU stays low, keep adding to it.  I
seem to remember having some weird NBAR issues with 12.3.   How much
traffic are you pushing through it currently?  20 to 30 customers
doesn't sound like it'd be a problem.

Hello,

I am looking into running NBAR along side with QoS in our network.  I
was
wondering what the list was doing if running NBAR.  I want to protect
against excessive file sharing customers or at least throttle those
specific
applications.  Some suggestions as the best place to configure this in a
network or what you all are doing is appreciated? Maybe even running on
a
mirror port?

My thoughts are placing on Cisco 7206 NPE-225/256MB box but am not sure
if
we should upgrade to a 7204VXR NPE-400/512Mb or not. This box runs
terminates static (no PPPoE) DSL customers and about 20 to 30
subinterfaces.  Although may move to PPPoE in the future. CPU usage is
light
and memory operates around 120MB free give or take.

Thanks in advanced!
