switch to switch bandwidth test problem

[srinuamujuri27]

Hi,

I have a problem in testing bandwidth on switch 10g port (trunk from core) to switch 10g port ( trunk sfp module 3560). These ports are configured with 10gbps bandwidth, full duplex and trunk. I have a vlan 187 interface on 3560 switch.

Now i am trying to test bandwidth on this trunk link using wan killer and prtg monitoring software from a client connected to core switch.

I am sending 100mbps traffic to vlan interface on 3560 switch it is working fine. but if i increase the traffic more than 100 mbps i am losing connectivity to switch 3560. these ports are 10g ports.

any one please help to solve these problem. and is there any other way to test 10g link switch to switch.

Thanks & Regards

Srinivas

Could you further clarify "I am sending 100mbps traffic to the vlan interface ...", because if you're sending traffic to the switch itself, you may be overloading the switch's control plane.  These switches only support their high port bandwidths for traffic that transits the switch.

Thanks for your response, could u please tell me how to test throughput on switch to switch 10g uplink. I am able to test from server to host 1g link  throughput by using iperf, but unable to test switch to switch uplink throughput.

Well if you had a hardware traffic generator, you might send 10g of traffic in one 10g uplink port, have it egress another 10g uplink port.  Or, you might send 1g into ten gig port, and have that traffic use the 10g uplink.  The latter might be accomplished with ten gig hosts too.

The prior, though, can be expensive and/or a bit of trouble to setup.  Generally Cisco switches meet their documented performance.  So, what is it you're trying to prove?  I.e. why to you need to use WAN Killer on a 10g uplink?
