•Global Configuration Command Queueing Parameters

Note•This appendix describes what happens during command migration; it does not describe the effect of any changes that you choose to make to the configuration after the migration completes.

•Any mls qos commands that are entered at the CLI generate a warning and are ignored.

12.2SX Commands and Comments	Migration Action	15.0SY Commands and Comments
mls qos •With no other configuration entered, the mls qos command enables significant changes in queueing and marking. •Conversion of the other 12.2SX QoS commands listed in this appendix occurs if the mls qos command exists in the configuration file that is being migrated.	Convert	auto qos default Configures ingress queueing on ports to which an ingress queueing policy is not attached. Configures egress queueing on ports to which an egress queueing policy is not attached. •If the configuration does not contain the mls qos marking ignore port-trust command, migration implements a non-default configuration on each port to which a service policy is not attached: –On each untrusted port, to duplicate the Release 12.2SX default port state (untrusted, which marks traffic), migration applies a platform qos trust none remark interface command, which marks all non-MPLS traffic. –On each trusted port, migration applies the equivalent platform qos trust interface command (because platform qos trust dscp is the default, it is not required on a port that was configured with the mls qos trust dscp command). Note •The auto qos default global configuration command does not enable QoS globally. 15.0SY does not have a global command to enable or disable QoS. •A service policy attached to an interface defines the QoS configuration of that interface. See the "Platform-Specific Policymap Command Migration" table for information about required manual configuration of some policy-map commands.
no mls qos •This is the default in Release 12.2SX. •Configured policies are not in effect and all QoS labels are preserved.	Ignore	•No 15.0SY equivalent; corresponds to the 15.0SY default nonconfigurable condition. •Any configured policies are in effect. •For IPv4 and IPv6 traffic, received DSCP is preserved, received CoS is ignored and the traffic is assigned a CoS value based on received DSCP. •For MPLS traffic, received EXP is preserved, received CoS is ignored and the traffic is assigned a CoS value based on received EXP. •For traffic that does not have a DSCP value, received CoS is preserved.
mls qos queueing-only •Disables policing and marking (preserves all ingress QoS labels) regardless of any configured service policies.	Convert	platform qos queueing-only •Except on ports configured with service policies, disables policing and marking (preserves all ingress QoS labels). •Configures ingress queueing on ports to which an ingress queueing policy is not attached. Configures egress queueing on ports to which an egress queueing policy is not attached.
no mls qos rewrite ip dscp	Convert	no platform qos rewrite ip dscp •As soon as possible, replace this command with per-port DSCP transparency configured with the set discard-class or set cos commands in service policies.
mls qos marking ignore port-trust •In Release 12.2SX, policy trust commands are ignored on trusted ports unless mls qos marking ignore port-trust is configured.	Ignore	No 15.0SY equivalent; corresponds to the 15.0SY default condition. •In Cisco IOS Release 15.0SY, policy trust commands are alway honored and, if configured, will be in effect on trusted ports regardless of any configured interface commands. •Used as an indicator that any configured 12.2SX port trust commands can be ignored.
mls qos marking statistics •Release 12.2SX supports 1,023 aggregate policers and configuring this command uses some of the available policer count to provide marking statistics for unpoliced traffic classes.	Convert	platform qos marking statistics •Release 15.0SY supports 16,383 aggregate policers and configuring this command uses some of the available policer count to provide marking statistics for unpoliced traffic classes.
mls qos police serial	Ignore	No 15.0SY equivalent; corresponds to the 15.0SY default nonconfigurable condition.

mls qos map policed-dscp max-burst	Convert	table-map policed-discard-class max-burst-map
mls qos aggregate-policer •Release 12.2SX supports configuration of up to 1,023 aggregate policers; some PFC QoS commands other than the police command are included in this count.	Convert	platform qos aggregate-policer •Cisco IOS Release 15.0SY supports configuration of up to 16,383 aggregate policers; some PFC QoS commands other than the police command are included in this count.
mls qos protocol	Convert	platform qos protocol •For DoS prevention.
mls qos statistics-export	Convert	platform qos statistics-export •For QoS statistics export.
mac packet-classify use vlan	Ignore	No 15.0SY equivalent; corresponds to the 15.0SY default nonconfigurable condition.

Table B-2 Platform-Specific Interface-Mode Command Migration 

12.2SX Commands and Notes	Migration Action	15.0SY Commands and Notes
mls qos vlan-based •The configured port trust state affects marking when the mls qos vlan-based interface command is configured.	Convert	platform qos vlan-based •The configured port trust state does not affect marking when the platform qos vlan-based interface command is configured. •A service policy attached to the Layer 3 VLAN interface defines QoS for ports where the platform qos vlan-based interface command is configured. •Service policies attached to ports configured with the platform qos vlan-based interface command are ignored.
mls qos trust cos •When the mls qos trust cos interface command is configured, unless the no mls qos rewrite ip dscp global configuration command is configured, ingress DSCP values are rewritten as defined in a CoS-to-DSCP map. •If configured, the mls qos trust cos interface command marks traffic when there are also applicable policy trust commands configured.	Convert	platform qos trust cos •Ignored if the platform qos vlan-based interface command is configured. •Ignored if there is an ingress service policy applied to the port and the platform qos vlan-based interface command is not configured. •Does not rewrite ingress DSCP values.
mls qos trust dscp •If configured, the mls qos trust dscp interface command marks traffic when there are also applicable policy trust commands configured.	Ignore	No 15.0SY equivalent; corresponds to the 15.0SY default nonconfigurable condition.
mls qos trust precedence •If configured, the mls qos trust precedence interface command marks traffic when there are also applicable policy trust commands configured.	Ignore	No 15.0SY equivalent; corresponds to the 15.0SY default condition. The lowest 3 bits of the ingress DSCP are not zeroed.
no mls qos trust	Convert	platform qos trust none remark •Ignored if the platform qos vlan-based interface command is configured. •Ignored if there is an ingress service policy applied to the port and the platform qos vlan-based interface command is not configured.

mls qos loopback	Convert	platform qos loopback
mls qos queue-mode mode-dscp	Convert	platform qos queue-mode mode-dscp
mls qos cos •After traffic has been marked, the original ingress CoS value is overwritten.	Convert	platform qos cos •The original ingress CoS value remains known. –By default, for IPv4 and IPv6 traffic, the ingress CoS value is overwritten by the DSCP value. –By default, for other traffic that is not tagged, the ingress CoS value is used, rather than the configured port CoS value. –Use the platform qos cos override interface command to use the value configured with the platform qos cos interface command instead of the original ingress CoS value.
wrr-queue bandwidth wrr-queue cos-map wrr-queue dscp-map wrr-queue queue-limit wrr-queue random-detect wrr-queue threshold	Convert	wrr-queue bandwidth wrr-queue cos-map wrr-queue dscp-map wrr-queue queue-limit wrr-queue random-detect wrr-queue threshold Note These commands are in effect only if the platform qos queueing-only or the auto qos default global configuration command is configured.
