Configuring CoS Queues in Layer 2 Circuit Trunk Mode

On ATM2 IQ interfaces, you can configure ATM CoS scheduling for AAL5 mode and
Layer 2 circuit trunk mode. For general information about ATM CoS, see "Configuring
ATM2 IQ VC Tunnel CoS Components" on page 347.
When you configure CoS scheduling in Layer 2 circuit trunk mode, the trunk is defined
on the logical interface, and four CoS queues are opened in the trunk. For each CoS
queue, you specify a priority and a transmit weight. CoS queues are serviced using
