Guidelines and Limitations While Configuring Static ARP

  • The host refresh time is twice the Layer 3 aging time (2*L3 age).
  • You must create a vRouter interface on the switch to send ARP request. For VRF aware static ARP, a VRF subnet should be created.
  • Host sends the ARP reply to the vRouter interface only. In the case of VRF aware static ARP, the ARP reply is sent to subnet anycast gateway IP.
  • In cases where there are multiple static ARP entries within the  same VLAN,  use the static-arp-delete ip ip-address mac mac-address vlan/vxlan command to delete the specific entry.
  • In the beginning, the Layer 3 entry should be activated with ping for the static ARP entry to be functional.
  • Static ARP entry can be created with VLAN or VXLAN options. You cannot have both VLAN and VXLAN at the same time while creating the static ARP entry. For VRF-aware static ARP, the static ARP entry should be created only with the VXLAN option.
  • When you create a static ARP entry with scope,  cluster or fabric, NetVisor  creates a static ARP entry configuration on one switch and  enables the static flag for Layer 3 entry in the L3 table for all the other switches in the fabric or cluster.
  • The modify static ARP command is not supported.
