Egressing-Frame Queues

(Multiple queues are used to support the prioritization of the traffic classes.)

Capacity of each
queue [frames]

Output Rate Limiting

Each of the 8 ports is individually configurable to:
- none
- 128 kbit/sec
- 256 kbit/sec
- 512 kbit/sec
- 1 Mbit/sec
- 2 Mbit/sec
- 4 Mbit/sec
- 8 Mbit/sec
Each of the two GigE ports is also configurable to:
- 100 Mbit/sec
- 200 Mbit/sec
- 400 Mbit/sec
- 800 Mbit/sec
Dynamics:
The frames egress one frame at a time, with the inter-frame gaps set to
provide the configured average bit-rate.

Frame Priorities

Priority Source
The source priority may be taken from:
3-bit Priority field in 802.1p ingressing frames.
3-bit Priority field in 802.1Q ingressing frames.
