CBQ

With the class-based queuing (CBQ) algorithm, you can specify a maximum bit rate, or bandwidth, for a queue. When that bit rate is exceeded, the switch drops all packets that exceed the 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.

For information on how to set up CBQ queueing, see "Setting Up CBQ" later in this chapter.

Note: Avaya recommends that you do not set a port using CBQ 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.
