Configuration Notes and Feature Limitations for DAI

The following configuration notes and limitations apply when configuring Dynamic ARP Inspection (DAI):

  • The maximum number of static DAI entries that can be configured is 6000. This value cannot be changed.
  • DAI can be configured on a maximum of 511 VLANs.
  • DAI is supported on a VLAN without a VE, or on a VE with or without an assigned IP address.
  • DAI is supported on Ethernet ports.
  • For default VLAN ID changes, DAI must be re-applied on the new default VLAN.
  • ACLs are supported on member ports of a VLAN on which DHCP snooping and Dynamic ARP Inspection (DAI) are enabled.
  • When a device receives the ARP packet with source 0.0.0.0, "allow source ip 0.0.0.0" is used to allow the packet when DAI is enabled.
