Field |
Value |
Description |
|---|---|---|
Policy ID |
For example: 5 |
Set and display the ID of the policy. If this parameter is set to 0, the system automatically allocates the policy ID. |
Automatically Assign |
Checked, Unchecked |
Selects whether the ID is allocated automatically. |
Policy Name |
64 bytes |
Set and display the name of the policy. |
Packet Color |
Red, Yellow, Green |
Packets may be marked in red, yellow or green. Different colors indicate different priorities for packet discarding. The packets marked in red are discarded with the highest priority. |
Lower Drop Threshold (256 bytes) |
0 to 480 |
Set the lower threshold for dropping the packets. When the queue length is lower than the lower drop threshold, the packets are not dropped. |
Upper Drop Threshold (256 bytes) |
0 to 480 |
Set the upper threshold for dropping the packets. When the queue length is higher than the upper drop threshold, all packets are dropped. The upper drop threshold should not be lower than the lower threshold. |
Drop Probability (%) |
1 to 100 |
Set the probability for dropping packets marked in different colors. The drop probability indicates the probability for randomly dropping packets when the queue length is higher than the lower drop threshold but lower than the upper drop threshold. |
