Configuring Proxy ARP

Proxy ARP allows Passport 8600 modules to respond to an ARP request from a locally attached host or end station for a remote destination. It does so by sending an ARP response back to the local host with its own MAC address of the router interface for the subnet on which the ARP request was received. The reply is generated only if the switch has an active route to the destination network. For more information about proxy ARP, see Networking Concepts for the Passport 8000 Series Switch.

To configure proxy ARP:

  1. From the Device Manager menu bar, choose VLAN > VLANs.
    2. The VLAN dialog box opens, with the Basic tab displayed.
  2. Choose a VLAN.
  3. Click the IP button.
    4. The IP, VLAN dialog box opens with the IP Address tab displayed.
  4. Select the ARP tab.
    5. The ARP tab opens.
  5. Click the DoProxy enable button.
  6. Click Apply.
    7. Proxy ARP is enabled for the VLAN.
