31.2 QoS Configuration
The main requirement is to enable and configure QoS on the desired switch. This section
provides:
• configuration guidelines
• sample procedures for enabling and configuring QoS
31.2.1 Configuration Guidelines
The following provides information to consider before configuring QoS:
• QoS policing cannot be configured on Linkagg interface.
• Traffic can be only classified per ingress port.
• There can be multiple ACLs per class map. An ACL can have multiple access control entries
that match fields against the packet contents.
• Policing cannot be done at the switch virtual interface level.
31.2.2 Sample Procedures
The following subsections provide examples of how to enable and configure QoS.
Commands are indicated in bold Courier type. Parameters are indicated in plain Courier type.
Additional information is indicated in Arial type.
Enable QoS
By default, QoS is disabled on the switch, which means that the switch offers best-effort service
to each packet regardless of the packet contents or size. All the packets map to egress queue 0
with both tail-drop thresholds set to 100 percent of the total queue size. When the buffer is full,
packets are dropped.
To enable QoS, enter the following commands from Privileged Exec mode.
1. configure terminal.
2. qos enable
Note: The no qos enable command disables QoS.
The following example shows enabling QoS.
DUT# configure terminal
