|
| Queue Number | Indicates the DiffServ Queue. |
|
| Possible responses are: |
|
| 0 = Best Effort (BE) |
|
| 1 = Assured Forwarding 1 (AF1) |
|
| 2 = Assured Forwarding 2 (AF2) |
|
| 3 = Assured Forwarding 2 (AF3) |
|
| 4 = Assured Forwarding 2 (AF4) |
|
| 5 = Expedited Forwarding (EF) |
|
| 6 = Routing Protocols (DiffServ priorities 6 and 7) |
| Max Queue Size | The maximum number of packets that can be queued for this priority. |
| Total Dropped Packets | Indicates how many packets of this priority have been dropped by QOS due to |
|
| lack of buffer space or filtering rules. |
| Total Enqueued Packets | Displays the number of packets, destined for the WAN, that have been received. |
| Current Depth | Displays the current number of packets of this priority that are queued. |
| Deepest Depth | Displays the most number of packets that have been queued at once for this |
|
| priority. |
|
| QOS Filter Statistics |
| Queue Number | The DiffServ Queue. (See Queue Number description above.) |
| Peak Info. Rate (%) | The maximum allowed rate for this priority, expressed as a percentage of the |
|
| DSL rate. |
| Committed Info Rate (%) | The committed rate for this priority, expressed as a percentage of the DSL rate |
| Peak Burst (ms) | Displays the interval in milliseconds for averaging the peak offered rate. |
| Committed Burst (ms) | Displays the interval in milliseconds for averaging the committed offered rate. |
| Total Packets Received | Displays the total number of packets of this priority that are destined for the |
|
| LAN. |
| Total Marked Packets | Displays the number of packets of this priority that exceeded the committed rate, |
|
| but not the peak rate, and were marked with a higher drop priority |
| Total Filter Packet Drops | Displays the number of packets of this priority that exceeded the peak rate and |
|
| that were, therefore, dropped. |
| Avg. DSL Bytes Per Packet | Displays the average size of packets for this priority, including all overhead. |
| Avg. Packet Rate Per second | Displays the average rate (in packets per seconds) for this priority. |
|
| QOS Latency Counts |
| Queue Number | The DiffServ Queue. (See Queue Number description above.) |
| Not Time Stamped | The packets with no incoming time stamp. (Often these are generated internal to |
|
| the modem.) |
| A ms to B ms | The number of packets of this priority whose time in the modem fell between A |
|
| and B milliseconds. (Time is measured from the point the packet arrives at the |
|
| modem’s processor until is passed to the ATM hardware for transmission.) |
|
| Possible ranges are (A ms to B ms): |
|
| 0 ms to 10 ms |
|
| 10 ms to 20 ms |
|
| 20 ms to 40 ms |
|
| 40 ms to 100 ms |
|
| 100 ms to 1000 ms |
|
| 1000 ms to 3000 ms |
|
| Larger than 3000 ms |
