Configuring ACL (Egress Direction)

This section contains payload examples and CLIs to demonstrate how to use the NX-API REST API to configure IP ACLs on Cisco Nexus 3000 and 9000 Series switches and to show how the REST APIs correspond to the CLI commands. For more information, see the Cisco Nexus 9000 Series NX-OS Security Configuration Guide.

CLI Commands

The CLI commands and options listed below are the 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 or the YANG tab to view the XML payload.

interface eth1/2
ip access-group bar out

Note: The property information for this example was added in Release 9.3(3).

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
aclEgress	sys/acl/mpls/policy/egress
aclIf	sys/acl/mpls/policy/egress/intf-{[name]}
aclInst	sys/acl/mpls/policy/egress/vty/acl

aclIf Properties

The following table contains information about the aclIf 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	nw:IfId (base:IfIndex)	Interface to which ACL is applied	eth1/1(Ethernet1/1) or pc1(port-channel), short name for interface Must match first field in the output of `show intf brief`. Example: Eth1/1 or Vlan100

aclInst Properties

The following table contains information about the aclInst 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	acl:Name (string:Basic)	Access Control List name	MAX SIZE: 63
