Hi, I am trying to auto-discover sensor on Cisco routers and it only discovers ping. These cisco routers have access-lists on them so only permit specific ports and protocols through. what port and protocols do I need to permit on the access-list for PRTG to get information from all the sensors that are available by default on Cisco routers? i.e other interfaces, Memory, CPU etc.. Thanks, Jaime

Hello,
usually it's at least SNMP on UDP Port 161 (on the target device).
best regards.
