Turn off<br>
<br>
ICMP redirects. Common problem in one arm routing<br>
configs.<br>
<br>
IMO it should be the default setting but it's not.<br>

Do you notice the same behavior with both UDP and<br>
<br>
TCP streams?<br>

MLXe,<br>
<br>
very lightly loaded, with only one card<br>
BR-MLX-10Gx8-X. <br>
<br>
Simplest of configuration, layer 2 link with VE<br>
<br>
interfaces. During inter-vlan routing where the<br>
ingress<br>
<br>
traffic and egress traffic are on the same port, say<br>
e1/2,<br>
<br>
the input traffic level will be fine, but the output<br>
traffic<br>
<br>
is effectively maxed out at about 50Mbps (on a 10GigE<br>
<br>
port). Shift hosts around so that the egress is a<br>
<br>
different port on the same card, bang problem gone and<br>
full<br>
<br>
expected traffic rates achieved.<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
Tried numerous code versions, from 05800a to 05900a to<br>
<br>
06000. No improvement.<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
Of course tried rebooting, new optics, new cabling. <br>
No<br>
<br>
errors incrementing on the interface. This is the<br>
silliest<br>
<br>
dumb problem in a long time. Any ideas are<br>
appreciated.<br>
<br>

Thanks!<br>
