Configuring Traffic Shaping
The system queuing policy is applied to both internal and front panel ports. When traffic shaping is enabled
Note
on the system queuing policy, traffic shaping is also applied to the internal ports. As a best practice, do
not enable traffic shaping on the system queuing policy.
Traffic shaping is not supported on the Cisco Nexus 9300 40G ports.
Note
Before You Begin
Configure random detection minimum and maximum thresholds for packets.
SUMMARY STEPS
1. configure terminal
2. policy-map type queuing {[match-first] policy-map-name}
3. class type queuing class-name
4. shape min value {bps | gbps | kbps | mbps | pps} max value {bps | gbps | kbps | mbps | pps}
5. (Optional) Repeat Steps 3 and 4 to assign tail drop thresholds for other queue classes.
6. show policy-map [type queuing [policy-map-name | default-out-policy]]
7. copy running-config startup-config
DETAILED STEPS

Purpose
Enters global configuration mode.
Configures the policy map of type queuing and then enters
policy-map mode for the policy-map name you specify.
Policy-map names can contain alphabetic, hyphen, or
underscore characters, are case sensitive, and can be up to 40
characters.
Configures the class map of type queuing and then enters
policy-map class queuing mode. Class queuing names are
listed in the previous System-Defined Type queuing Class
Maps table.
Assigns a minimum and maximum bit rate on an output queue.
The default bit rate is in bits per second (bps).
