Hi There,

I had a rather hard time with our Cisco 2900 Series Router (1 4G Cellular and 2 Giga EHWICS) and our Cisco 1900 Series Router (single Port) and the Netflow and SNMP sensors... in the end it was all down to the right configuration on the cisco... therefore find my solution here:

Some Cisco Commands for PRTG Sensors Enable Netflow for specific Interface interface FastEthernet 0/1 (general command: interface [interface name] [interface number]) ip route-cache flow

Configure Netflow ip flow-export version 5 (or version 9) ip flow-cache timeout active 5 ip flow-cache timeout inactive 10 ip flow-export destination [ip] [port] (port 9991, can be up to 10 different IPs)

Disable Netflow for specific IP and Port no ip flow-export destination [ip] [port] Disable Netflow for specific Interface interface [interface name] [interface number] no ip route-cache flow exit Configure SNMP SNMP-Server view [ViewName] internet included

> in case return %Bad OID internet does not work, use ISO or 1.3.6 instead

> included means MIB family is included

SNMP-Server group [GroupName] v3 priv read [ViewName] write [ViewName]

> v3 could be v2c or v1

> priv means using authPriv Security Model, could be auth for authNoPriv and authNoPriv for no AuthNoPriv

> read/write could be access, context, notify

SNMP-Server user [UserName] [GroupName] v3 auth MD5 [Password] priv DES [Password]

> MD5 could be SHA

> DES means using Data Encryption

Copy running config as persistent config copy running-config startup-config

PRTG SNMP Setting Make this settings on Local Probe Level to make it available for all devices! SNMP Version: v3 Authentication Type: MD5 User: [UserName] Password: [Password] Encryption Type: DES Data Encryption Key: [Password] Context Name: leave empty SNMP Port: 161 (Firewall Settings UDP!) SNMP Timeout: 5 PRTG NetFlowV5 Sensor Receive NetFlow Packets on UDP Port: 9991 Sender IP: leave empty or specify Ciscos IP Receive Packets on IP: IP of PRTG Server Actie Flow Timeout 5 Rest up to what you want....
