Configuring Policy Maps

This section contains payload examples and CLIs to demonstrate many of the QoS policy map configuration options and to show how the REST APIs correspond to the CLI commands.

Defining a Policy Map

Defining a Policy Map

POST http://<mgmt0_IP>/api/mo/sys/ipqos/queuing/p.json

{
 "ipqosPMapEntity": {
   "children": [
     {
       "ipqosPMapInst": {
         "attributes": {
           "matchType": "match-all",
           "name": "foo"
}}}]}}

{
    imdata:[]
}

<System>
  <ipqos-items>
    <queuing-items>
      <p-items>
        <name-items>
          <PMapInst-list>
            <name>foo</name>

        </name-items>
      </p-items>
    </queuing-items>
  </ipqos-items>
</System>

This example creates a named object that represents a set of policies that are to be applied to a set of traffic classes.

CLI Command

The CLI command below is the equivalent to the payload example displayed in the pane on the right. Click the DME tab in the top-left corner of the right pane to view the JSON payload or the YANG tab to view the XML payload.

An instance of the interface for QoS must be initialized before configuring QoS. The interface can be any of the following types:

ethernet - Ethernet IEEE 802.3z

loopback - Loopback interface

mgmt - Management interface

port-channel - Port Channel interface

Note: Sub-interfaces and breakout ports for the above are also supported.
