You issue the show running-config command on a Cisco 3700 series router named RouterA and receive the following partial output:

• 350-401 : All Parts

Explanation:
Packets will be sent in the order they are received. In this scenario, class-based weighted fair queuing (CBWFQ) and low latency queuing (LLQ) are used, as indicated by the priority and bandwidth commands. However, only the class-default class can use weighted fair queuing (WFQ); the other classes can use only firstinfirstout (FIFO) queuing within the class. With FIFO queuing, the first packet received is the first packet transmitted.
A traffic class can be prioritized over other traffic classes, but traffic within that class is processed in the order in which the traffic is received, without regard for packet size, protocol, or IP precedence. For example, Voice over IP (VoIP) packets might be transmitted ahead of File Transfer Protocol (FTP) packets, and FTP packets might be transmitted ahead of VoIP packets. Similarly, smaller packets might be transmitted ahead of larger packets, and larger packets might be transmitted ahead of smaller packets.
