Hi

Basically you must add the PRTG IP  into the logging configuration, for example:

conf t

logging on

logging host <PRTG IP> 

logging trap 5

logging buffered 5

logging buffered 100000

logging source-interface <interface o vlan>

Into the SNMP configuration you must include the community string (what can be any phrase) and server, example:

snmp-server host <PRTG Server> version 2c <Community phrase>

If you have more than 1 server you can use a standar ACL to specify the host, for example:

ip access-list 10 standar SNMP-SERVERS

permit host 1.1.1.1

permit host 2.2.2.2

permit host 3.3.3.3

snmp-server community <community string> ro <ACL name or number>

Hope it is useful
