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.
