If we enable Auto-discovery using Seed routers option or subnet, i would like to understand how below option would work?

Discover Subnets Using - Discovers the subnets that use the following tables:

ARP tables - Specifies that the subnet uses the Address Resolution Protocol (ARP) tables.

Cisco CDP tables - Specifies that the subnet uses the Cisco Discovery Protocol (CDP) tables

When both options are used, ARP tables and CDP tables, which table will be read first?  ARP or CDP?


Release : Any

Component : Spectrum Discovery & Modeling


In tests run in the lab, the CDP table is read first and then the ARP table.
