Issue Description

Q:
What's the difference between the "Available bandwidth" and the "Left guaranteed bandwidth"?

Alarm Information

Null

Handling Process

A:
1. The "Left guaranteed bandwidth(kbps) " value got by command  "display port info" means the left bandwidth which calculated by OLT system. This value would be decreased after add a ONT. When we add a ONT, we would configure its bandwidth, this value is related with this kinds of ONT configuration. It is a static value for us.
The "Available bandwidth" value got by command "display port state " means the real available bandwidth. After added some ONTs and configured the bandwidth values for them, not all ONT would be running and use all their bandwidth, so we can get more bandwidth here. It is a dynamic value for us.
2. The downstream is broadcast, there is no bandwidth concept in it.
If the traffic is larger than 2.5G, the redundant would be abandoned.
