How Nectus selects Management interface for the discovered devices?


For each router or switch found during discovery Nectus has to select one interface that will be used as a primary monitoring

interface for basic reachibility checks, destination for SNMP  queries etc..

Here is the selection order logic that implemented in Nectus Discovery Service:

  1. Select Interface that has assigned IP address associated with current DNS record for device Hostname
  2. Select Interface that starts with “Mgmt” (for example: Mgmt0)
  3. Select Interface that starts with “Loopback” (Lowest number if preferred)
  4. Select Interface that starts with “VLAN”  (Lowest number of preferred)
  5. Select Interface with lowest IP Address
