Problem Description

The customer has two external network lines, and uses traffic control Policies control the single IP speed of the internal network to 2mb/s, but sometimes the single IP speed can reach 4mb/s

Process——

  1. Check the Bandwidth Channel under traffic management and find that there are two effective links. The upper limit of a single user on each effective link is 2mb/s.

Root cause

When the intranet is connected to multiple lines and the traffic of a single IP in the intranet will be sent to multiple external lines at the same time, the maximum speed of a single IP should be the sum of the single-user upper limits of the two effective links.

solution

Modify the Bandwidth Channel Policies and set the single-user upper limit of each effective link to 1mb/s
