Learn how to configure proxy ARP using the Cisco NX-OS style CLI. This procedure enables proxy ARP on a specified EPG within your Cisco ACI environment.

Before you begin

  • The appropriate tenant, VRF, bridge domain, application profile and EPG must be created.

  • Intra-EPG isolation must be enabled on the EPG where proxy ARP has to be enabled.

Procedure

  1. configure

    Enters configuration mode.

    Example:

    
                        apic1# 
                        configure

  2. tenant tenant-name

    Enters the tenant configuration mode.

    Example:

    
                        apic1(config)# 
                        tenant Tenant1

  3. application application-profile-name

    Creates an application profile and enters the application mode.

    Example:

    
                        apic1(config-tenant)# 
                        application Tenant1-App

  4. epg application-profile-EPG-name

    Creates an EPG and enter the EPG mode.

    Example:

    
                        apic1(config-tenant-app)# 
                        epg Tenant1-epg1

  5. proxy-arp enable

    Enables proxy ARP.

    Note

    You can disable proxy-arp with the no proxy-arp command.

    Example:

    
                        apic1(config-tenant-app-epg)# 
                        proxy-arp enable

  6. exit

    Returns to application profile mode.

    Example:

    
                        apic1(config-tenant-app-epg)# 
                        exit

  7. exit

    Returns to tenant configuration mode.

    Example:

    
                        apic1(config-tenant-app)# 
                        exit

  8. exit

    Returns to global configuration mode.

    Example:

    
                        apic1(config-tenant)# 
                        exit

Examples

This example shows how to configure proxy ARP.


                apic1# conf t
                apic1(config)# tenant Tenant1 
                apic1(config-tenant)# application Tenant1-App 
                apic1(config-tenant-app)# epg Tenant1-epg1                      
                apic1(config-tenant-app-epg)# proxy-arp enable  
                apic1(config-tenant-app-epg)# 
                apic1(config-tenant)#
