Hi community I am currently testing some rate limiting on a S series switch. The idea is to rate limit all traffic on a specific port to 200 Mbps. To test the rate limit I have a Iperf Server connected to a 1Gbps port and a client PC connects to the "200 Mbps Rate limited" port For a benchmark we first run the iperf test with out and rate limit applied. Both the server and the client is connected to a 1Gbps port. The iperf results indicate almost 900Mbps throughput. When I apply my 200Mbps policy to the port, iperf reslut goes down to 3Mbps, The COS config on the switch is as follows: # Chassis Firmware Revision: 08.61.02.0002 ! # cos port-config ! # cos port-resource set cos port-resource irl 0.1 0 unit mbps rate 200 set cos port-resource orl 0.1 0 unit mbps rate 200 ! # cos reference set cos reference irl 0.1 8 rate-limit 0 set cos reference orl 0.1 0 rate-limit 0 ! # cos settings set cos settings 8 priority 1 txq-reference 8 irl-reference 8 orl-reference 0 ! # cos state set cos state enable ! # cos syslog ! End The Cos is then applied to the port using a Policy # policy set policy profile 1 name "SmartCape Bandwidth Limit" pvid-status enable pvid 4095 cos-status enable cos 8 set policy rule admin-profile port ge.1.9 mask 16 port-string ge.1.9 admin-pid 1 I have played with various settings, from 100Mbps to 500Mbps but I do not see the speeds that I expect. I have also tried to set the rate limit to 20% of the port but this also give me 3Mbps. Anything that I am missing here? Thx
