NSX-T Controller Tables- TEP and ARP Tables

Today we are going to talk about the Tables maintained by the NSX-T controller. The table maintained by NSX-T controllers are as below

  • Global MAC address to TEP table
  • Global ARP table, associating MAC addresses to IP addresses
Fig 1.1- Physical Topology NSX-T

Global MAC address to TEP table
When the vNIC of a VM is attached to a segment/logical switch, the NSX-T Controller is  notified of the MAC address as well as the TEP by which this MAC address is reachable. 

Unlike  individual  transport nodes that only learn MAC addresses corresponding to received traffic, the  NSX-T Controller has a global view of all MAC addresses of the vNIC declared in the NSX-T  environment.

Global ARP table, associating MAC addresses to IP addresses
The NSX-T Controller also maintains an ARP table in order to help implement an ARP suppression mechanism. The N-VDS snoops DHCP and ARP traffic learn MAC address to IP association. 

Those associations are then reported to the NSX-T Controller.
