    Why Discovery scan ports different to snmp (161, 162) if only have SNMP Credentials configured?

      Share This:

      I have a Discovery 11 on production but when we monitor the traffic during the discovery process, we can see the use of multiple ports to achieve the task. Attached is the image of the firewall showing the traffic of discovery process and the same for a Cisco Discovery process without this issue in the same network.

       

      ¿There's something i can do to avoid the port scanning by the Discovery?

       

      Discovery using ports 147, 148, 149, 319, 60.

      Cisco Discovery using only snmp port on the same network.
