CLI Commands

The CLI commands are equivalent to the payload examples 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. Click the YANG tab to view the XML payload.

nbm flow-policy
  policy POL_1
   ip group-range 237.1.1.1 to 237.1.1.10
    priority critical

Verifying a DME Configuration

The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
nbmFlowPolicyTable	sys/nbm/conf/flowpolicytable
nbmFlowPolicyDom	sys/nbm/conf/flowpolicytable/dom-default
nbmFlowPolicy	sys/nbm/conf/flowpolicytable/dom-default/name-POL_1
nbmFlowPolicyRange	sys/nbm/conf/flowpolicytable/dom-default/name-POL_1/bgn-[237.1.1.1]-end-[237.1.1.10]

nbmFlowPolicyRange Properties

The following table contains information about the nbmFlowPolicyRange properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
groupBegin	nbm:nbmMcastIpAddr (address:Ip)	Flow Policy Group range start.	Multicast Group Range IP only Value must match ipv4 or ipv6 known format
groupEnd	nbm:nbmMcastIpAddr (address:Ip)	Flow Policy Group range end.	Multicast Group Range IP only. Must be same as groupBegin in case of specific group policy. i.e when range is not desired. Value must match ipv4 or ipv6 known format
prio	nbm:nbmGroupPriority (scalar:Enum8)	Flow Policy Group range priority.	SELECTION: 0 - LOW 4 - CRITICAL DEFAULT: LOW

nbmFlowPolicyDom Properties

The following table contains information about the nbmFlowPolicyDom properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
name	naming:Name256 (string:Basic)	The name of the object.	MAX SIZE: 63

nbmFlowPolicy Properties

The following table contains information about the nbmFlowPolicy properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
