Command Line Reference Guide

Quality of Service (QoS) | 807
This command can be applied on both physical interfaces and port channels. When you set the
service-class dynamic for a port channel, the physical interfaces assigned to the port channel are
automatically configured; you cannot assign the service-class dynamic command to individual
interfaces in a port channel.
On the C-Series and S-Series all traffic is by default mapped to the same queue, Queue 0. If you honor
dot1p on ingress, then you can create service classes based the queueing strategy using the command
service-class dynamic dot1p from INTERFACE mode. You may apply this queuing strategy to all
interfaces by entering this command from CONFIGURATION mode.
• All dot1p traffic is mapped to Queue 0 unless service-class dynamic dot1p is enabled on an
interface or globally.
• Layer 2 or Layer 3 service policies supercede dot1p service classes.

Usage
Information
Guarantee a minimum bandwidth to different queues globally using the command service-class
bandwidth-weight
from CONFIGURATION mode. The command is applied in the same way as the
bandwidth-weight command in an output QoS policy. The bandwidth-weight command in
QOS-POLICY-OUT mode supercedes the service-class bandwidth-weight command.

Syntax

Enter the bandwidth-weight. The value must be a power of 2.
Range 1-1024.
