Cisco IOS XE Release Number
From Cisco IOS XE Release 3.1.0s onwards, a warning message is displayed when no command is executed
if you have not configured classification and you are trying to execute the no commands for no plim qos
input map ip precedence precedence-value queue {strict-priority | 0} and no plim qos input map ip dscp
dscp-value queue {strict-priority | 0}.
Old behavior
When the no form of command was executed for classification commands such as no plim qos input map
ip precedence precedence-value queue {strict-priority | 0} and no plim qos input map ip dscp dscp-value
queue {strict-priority | 0}, a warning message was not displayed when no form of command was executed
on queues for which classification was not configured and the no form of command was accepted.
New Behavior
The no form of the classification commands returns an error message if you have not configured the
classification and you are trying to execute the no command from Cisco IOS XE Release 3.1.0s onwards. For
example, by executing the plim qos input map ip precedence 4 5 queue strict-priority command the ip
precedence value is configured on queue with strict-priority. If you are executing the no plim qos input map
ip precedence 4 5 queue 0 for which the configuration has not been configured, it shows an error message
"% Precedence 4 not configured for queue 0. Cannot use [no] option to remove it." However, if you are
executing the no command for a queue for which configuration has been done, the no form of the command
works fine. The error message is also displayed if no form of command is executed for other classification
command such as no plim qos input map ip dscp dscp-value queue {strict-priority | 0}, if classification is
not configured for the queue and you are executing the no form of command.
Classifying IPv6 Packets
To classify all the IPv6 packets as either high priority or low priority, or to classify the IPv6 packets with
specific traffic class values such as high or low, execute the following set of commands in the Configuration
ingress class map mode:
SUMMARY STEPS
1. enable
2. configure terminal
3. ingress-class-map 1
4. map ipv6 all queue strict-priority
5. map ipv6 tc tc-value queue strict-priority
6. exit
7. interface {POS | Serial} interface-path-id
8. plim qos input class-map index-id
