How do we check if ACI LEAF interface are configured with QOS ?

Network_Sarovani · ‎01-27-2022

Hi Experts ,

Do we configure QOS in ACL LEAF switches ?

How do we check if QOS is configured on the leaf switch ?

How do we check the running config for interface APIC GUI ?

hi @Network_Sarovani

using this command will show you the details of the QoS on an interface , if you have edited the general QoS you should see the same impact on all the interfaces.

in ACI you can apply a Custom Policy on one EPG so this policy will be applied on all the the attached interfaces:

Procedure

Step 1

Log in to your Cisco APIC GUI.

Step 2

From the horizontal navigation bar, select Tenants > <tenant-name>.

Step 3

In the left-hand navigation pane, expand <tenant-name> > Policies > Protocol > Custom QoS.

Step 4

Right click the Custom QoS and choose Create Custom QoS Policy.

Step 5

Provide the name and an optional description of the custom QoS policy information.

Step 6

Create a DSCP mapping for one or more QoS priority levels.

The DSCP mapping allows you to map ingress DSCP values to a QoS priority level as well as the egress DSCP and CoS value for traffic that leaves the ACI fabric. For each mapping, you can specify the following fields:

Name Description

Priority	The QoS priority level to which the DSCP values will be mapped.
DSCP Range From	The start of the DSCP range.
DSCP Range To	The end of the DSCP range.
DSCP Target	The DSCP value for egressing traffic.
Target Cos	The CoS value for the egressing traffic.

Step 7

Create a CoS mapping for one or more QoS priority levels.

The CoS mapping allows you to map ingress CoS values to a QoS priority level as well as the egress DSCP and CoS value for traffic that leaves the ACI fabric. For each mapping, you can specify the following fields:

Name Description

Priority	The QoS priority level to which the DSCP values will be mapped.
Dot1P Range From	The start of the CoS range.
Dot1P Range To	The end of the CoS range.
DSCP Target	The DSCP value for egressing traffic.
Target Cos	The CoS value for the egressing traffic.

Step 8

Click Submit to save the changes.

Step 9

Attach the custom QoS policy you created to an EPG.

Navigate to Tenants > <tenant-name> > Application Profiles > <application-profile-name> > Application EPGs > <application-epg-name>.
In the main window pane, select Policy > Generalthe custom QoS policy you created.
In the main window pane, select the custom QoS policy you created from the Custom QoS drop down menu.

Click Submit to save the changes.

Configuring QoS Directly on L3Out Using GUI

This section describes how to configure QoS directly on an L3Out. This is the preferred way of configuring L3Out QoS starting with Cisco APIC Release 4.0(1).

Procedure

Step 1	From the main menu bar, select Tenants > <tenant-name> .
Step 2	In the left-hand navigation pane, expand Tenant <tenant-name> > Networking > L3Outs > <routed-network-name> > Logical Node Profiles > <node-profile-name> > Logical Interface Profiles > <interface-profile-name>. You may need to create new network, node profile, and interface profile if none exists.
Step 3	In the main window pane, configure custom QoS for your L3Out. You can choose to configure a standard QoS level priority using the QoS Priority drop-down list. Alternatively, you can set an existing or create a new custom QoS policy from the Custom QoS Policy dropdown.

hope that could help you.

in addition you can use this CLI commands:
Fabric QoS Debugging - CoPP CLI
<show copp policy>
<show system inernal aclqos brcm coppp entries unit 0> - CoPP statistics (red = dropped, green = allowed)
<show system internal qos classes> - shows QoS classes configured
<show system internal qos vlan all> - shows QoS classes/policices configured per vlan
<show system internal qos ppf [pinst|nodes]> - shows ppf details
<show system internal aclqos qos classes> - shows QoS classes configured in hardware
<show system internal aclqos qos vlan (vlanID)> - shows the QoS DSCP/dot1p policy configured for a vlan in HW
<show system internal aclqos qos policy summary> - shows QoS DSCP/dot1p policy summary
<show system internal aclqos qos policy detail> - shows QoS DSCP/dot1p policy in detail

Can we configure QOS on ACI for particular application ? say the application name or url is example.com (10.10.10.1)
