[c-nsp] Cisco 7304 as a Border router

Correction IXIA did had 2giga ports :) so traffic went out via one giga
port and in on the other. However I am told that CEF wasn't running and
CPU spiked :) that would explain the packet loss not the ultimate factor
but a big one.

S6 is the max out just now.  Also youre Ixia only had 1 gig port??  How
did
you see packet drops.  I ran the rfc throughput tests on the box and had
these results.

100.00  	100.00  	100.00  	100.00	

in other words I never dropped a packet.  With QOS configured on the gig
links I got....

>From above with qos configured on the gig interfaces I halved the gig
port
at 64 byte packets and lost 4% at 128 bytes.

HTH - btw these figures are for my testing.  In other words if you buy
one
based on the above figures then don't get the exact same throughput
don't
come moaning to me ;-D
