ARP

This chapter provides examples on how to use Netconf to manage ARP configurations on AsterNOS devices.

Create ARP Global Configurations

Caution

NOTE: The default expiration time for ARP is 300 seconds.

Request example to create ARP global configurations via edit-config.

<config><top>
  <arp-global operation="create">
    <arp-dynamic-learning>
      <expire-time>1000</expire-time>
    </arp-dynamic-learning>
    <log-enable>True</log-enable>
  </arp-global>
</top></config>

Response example

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:0f6026e2-0dc9-4c98-a169-3c4354f85976">

Enable ARP Proxy On Vlan Interface

hint{type=“warning”} NOTE: ARP proxy only supports configuration on VLAN interface. The ARP proxy currently only supports merge and get operations. To disable this feature, the mode needs to be set to disable.

Request example to enable ARP proxy on vlan interface via edit-config.

<config><top>
  <vlans>
    <vlan operation="create">
      <vlanid>100</vlanid>
    </vlan>
  </vlans>

    <interface>
      <name>Vlan100</name>
