In the web authentication scenario on the N18K, the ARP proxy mechanism is as follows:
  • The N18K sends the ARP requests to users only in the authentication-exempt VLANs.
  • After a user is successfully authenticated, a static ARP entry is generated.
  • In the VLAN that requires authentication, only when the authentication-exempt user actively initiates an ARP request, the N18K device generates an ARP entry for the authentication-exempt user.


Precautions for ARP proxy mechanism planning:
  • This type of terminals should be uniformly planned in the authentication-exempt VLAN.
