Usage Guidelines

Before you downgrade from Cisco NX-OS Release 5.2(x) or 5.1(x) or higher version to Cisco NX-OS Release 5.0(x) or an earlier release, remove all the user defined network-qos and queuing policies configured on F series modules. Use the clear qos policies command to remove the defaults for F series modules. An internal process failure can result if the QoS policies are not removed prior to the downgrade. Downgrade should be done after running this CLI command.

This command does not require a license.

6.1(3)

This command was introduced.


Usage Guidelines

To make software downgrades non-disruptive from the version 6.1(3) and higher version to lower version, the following steps are required before the software downgrade:

All the user defined and cloned 8e-4q4q template queuing policies should be detached manually from all the interfaces in each VDC

The default-nq-8e-4q4q-policy or the user defined or the cloned 8e-4q4q template network-qos policy should be detached from the system qos

All the user defined and cloned 8e-4q4q template network-qos policies should be removed manually from the default VDC

All the user defined 8e-4q4q template queuing policies should be removed manually from all the VDCs

Use the CLI command clear qos policies 8e-4q4q in default VDC to clear the default 8e-4q4q template policies. This command clears PPF (Portability Policy Format) nodes of 8e-4q4q template policies.

After executing clear qos policies 8e-4q4q command, the user MUST do downgrade. Otherwise the behavior will be unexpectedThis command does not require a license.


Note Reloading a F series module will bring up the default 8e-4q4q template policies.


 
   

Examples

This example shows how to clear the 8e-4q4q template network-qos and queuing policies from all the VDC:

switch # conf t
switch# clear qos policies 8e-4q4q

6.1(3)

This command was introduced.


Usage Guidelines

If an access-list matched inside a qos class-map has "deny" entry, we skip the qos action for that class-map. If any subsequent class-maps has the same acl entry but with permit action, then the qos action of the class-map having permit acl entry is applied. If not, no action is applied on the packets that matched the qos class-map having deny acl entry.

The customers can use this feature to selectively not apply qos to traffic from specific hosts (IP addresses) and to apply qos to all other hosts in that subnet/network.

Before this deny ace support, the permit or deny actions in an access-list are ignored by qos and only the classification criteria (src-ip/dst-ip/protocol/src-port/dst-port) of an acl is used for classification.

This command does not require a license.

switch(config)# hardware access-list allow deny ace

6.1(2)

Starting with the Cisco NX-OS 6.1(2) release, DSCP to IVL is supported on IPV6 using F2E modules.

6.1(1)

Starting from 6.1(1) release DSCP to IVL is supported on ingress direction on F2 modules using match dscp value command with Class-maps "2q4t-8e-in-q1" and "2q4t-8e-in-q-default".

4.0

This command was introduced.


Usage Guidelines

match dscp command is only applicable to queues which have at least one cos value associated with it. Default queue should always have cos value associated with it if not all DSCP value are mapped to non-default ingress queue.

The dscp queuing is automatically disabled when the user removes all the match dscp's (using "no match" statements).

If match dscp values is used under 2q4t-8e-in-q1 with a few DSCP values, all remaining values get mapped to the default queue.

Below are some of the restrictions for this command:

Only supports ingress queues for F2 modules for 8E template. (It does not support egress queues, M1 queues, or fabric-qos queues.)

- Ingress queues must have at least one cos value associated with it without restriction which Cos value is used.

- Cannot be used in user defined class-maps.

- Cannot be used in a user configuration session.

- Command must be disabled for ISSD otherwise the ISSD will be disruptive.

- By default DSCP to IVL is disabled.

- Queue-limit command cannot be specified based on COS or DSCP value. The configured queue-limit sizes are applicable for both DSCP and COS values.

- There are no additional statistics generated to differentiate how many packets are matched on DSCP or COS.

- When DSCP to IVL is enabled an interface will use DSCP value as trusted for IP packets and COS value will be trusted for NON-IP packets.

- Fabric Path Interface and FEX Port-channel interfaces do not support DSCP to IVL mapping.

- DSCP to IVL is not supported for IPv6 packets.

DSCP to IVL mapping change is disruptive operation and might cause BFD/Routing protocols to Flap.

This command does not require a license.

Examples

This example shows how to match the DSCP value:

switch(config)# class-map type queuing match-any q4t-8e-in-q1
switch(config-cmap-que)# match dscp 1
switch(config-cmap-que)#

Specify a comma-separated list of values—cos 1, 4-6

This command does not require a license.

Examples

This example shows how to configure WRED for a queue by setting the default WRED thresholds followed by thresholds that apply to CoS values 5 and 7:

random-detect cos-based

To configure weighted random early detection (WRED) on both ingress and egress queues by setting minimum and maximum packet drop thresholds, use the random-detect cos-based command. To remove a WRED configuration, use the no form of this command.

random-detect cos-based [aggregate [minimum-threshold] {min-threshold [packets | bytes | kbytes | mbytes | ms | us] | percent min-percent-of-qsize} [maximum-threshold] {max-threshold [packets | bytes | kbytes | mbytes | ms | us] | percent max-percent-of-qsize}]

This command was introduced.


Usage Guidelines

The random-detect cos-based command is required when you configure WRED to establish default thresholds for class of service (CoS) values for which you do not define specific thresholds.

The minimum and maximum threshold units must match.

The system drops packets that exceed the minimum threshold at an increasing rate as the maximum threshold is reached. By default, the units are in packets,

WRED and tail drop cannot be configured in the same class. For information about configuring tail drop, see the queue-limit command.


Note You cannot configure WRED on ingress 10-Gigabit Ethernet ports.


This command does not require a license.

Examples

This example shows how to configure WRED for a queue by setting the default WRED thresholds followed by thresholds that apply to CoS values 5 and 7:

switch(config)# policy-map type queuing match-first my_queue
switch(config-pmap-que)# class type queuing 1p3q4t-out-pq1
switch(config-pmap-c-que)# random-detect cos-based aggregate 10 mbytes 20 mbytes
