Bandwidth usage mismatch with virtual line

Denny Chanditya Posted 16 Nov 2022 10:48

Hello, i have IAM 5200 with OS 13.0.19
i have a problem with our internet link, we have 70Mbps connection but when i check on sangfor it only limit to 60Mbps.

Virtual line config on bandwidth management


Monitoring Traffic (it was stable on 60Mbps before)


and i setup the low bandwidth usage to 50%, for the high bandwidth usage i turn it off.

Is there any other configuration that i need to check about this issue?
i see our bandwdith management policy is not limited to 60Mbps, the default channel also limit at 70Mbps

There are 2 factors:
1. Type of connection either LAN or WIFI, usually WIFI connection decrease bandwidth
2. The ISP provided bandwidth is "up to", means it is not 100% they only give 80 to 90 percent of bandwidth
Is this answer helpful?

Hi Denny, could you try to disable the bandwidth management policy to see if the bandwidth could be improved over 60Mbps? If not, you can try to enable passthrough mode to prevent the data flow is being restricted by the Sangfor IAM policy.

70 Mbps doesn't means that you will get full MBs, there are slight variation acceptable and also there are uploading/downloading MBs in this full scenarios but you can ask your ISP, he will clarify it more.

Sangfor IAG's output is accurate. You must check it with your ISP Provider

Try to set the Inbound and Outbound bandwidth to unlimited and see what is the result.
