Usage Information
To honor all incoming 802.1p markings on incoming switched traffic on the interface, enter this command. By
default, this facility is not enabled (that is, the 802.1p markings on incoming traffic are not honored).
You can apply this command 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.
•
All dot1p traffic is mapped to Queue 0 unless you enable the service-class dynamic dot1p command
on an interface or globally.
• Layer 2 or Layer 3 service policies supersede dot1p service classes.
Use this command in Configuration Terminal Batch mode to honor the incoming 802.1p markings in a dual-homing
setup.
service-class wred backplane
After you create a WRED profile with ECN functionality, specify per-queue granularity for backplane ports and include the WRED profile in
a service class. Using this command, you can enable or disable queue-specific settings and specify minimum and maximum buffer
thresholds in the WRED profile applied to each packet color-code. Also, you can specify the maximum drop rate percentage for yellow and
green profiles. The per-queue profile configured is applied to all the backplane ports.
