Hello,


I have a S5700 switch installed in one of my POPs, uplink is GE0/0/1 and i deliver a 700mbps circuit in port GE0/0/25 to one of my clients.


Problem is, my client is trying to certify the 700Mbps BW using RFC 2544 device and its getting 490Mbps results.

From the logs i understand that for that kind of test, the switch detects a MAC-FLAP and then lowers the BW of the port to 50% (thats why client gets 490Mbps results)

Is there any way to disable or edit this feature (per vlan and/or interface) so my client can get the 700Mbps result?



Thank you

Ramiro.

@RamiroP hello, the logs indicates the potential network loop. You are kindly advised to investigate the problem rather than disable the anti-loop function.
Anyway, you can disable the input broadcast detection through command set flow-change-ratio input-broadcast-detect disable, please refer http://support.huawei.com/hedex/hdx.do?docid=EDOC1100101073&id=EN-US_TASK_0177101957&text=Disabling%252520Detection%252520of%252520a%252520Sudden%252520Broadcast%252520Traffic%252520Volume%252520Change%252520in%252520the%252520Inbound%252520Direction%252520of%252520Interfaces&lang=en

Hello,
Please find below the Handling Process

Define ACL:

acl 4000
rule permit vlan-id xxx
Apply ACL in system view:
traffic-limit inbound acl 4000 cir 10000
traffic-limit outbound acl 4000 cir 10000

Thanks

Hello Chen, i know the problem is that the client needs to certify circuit by using RC2544 instrument, which seems to activate the switch protection.

Regards,
Ramiro
