CBWFQ

The class-based weighted fair queueing (CBWFQ) algorithm is a combination of the CBQ and WFQ algorithms. CBWFQ makes more complex management of traffic possible. Using CBWFQ, you can set:

• The maximum bit rate.

The bit rate that you set should be the long-term average rate of transmission. Traffic that does not exceed this rate is guaranteed transfer.

• Burst thresholds
• The action that you want the switch to take when the bit rate exceeds the maximum bit rate.
• Drop the packets

or

• Forward the packets according to the weight of the queue

Note: Avaya recommends that you do not set a port using CBWFQ as the source port or mirror port for a port mirror. When the switch limits the bandwidth of a port, packets are subject to random drop. If packets from a source port or mirror port are dropped, the mirror traffic may not match the source traffic.
