Add them both as "parents router,switch" Make sure router and switch are defined in the hosts.cfg file before your dual homed host.

I have a host that is situated behind a router. No problem, I just add that router as a parent for my host. However, what do I do when I have a dual homed host with one IP in the 172.20 and one in the 10. range? Where the 172.20 just connects to a Cisco Catalyst and the 10. range to a router? What parent do I use in the parents directive, the router or the switch? Both interfaces are being used for service checks as one network is a private gigabit backbone and the other is open to the LAN. Is there any use in adding them both as parent, and what consequences will this have? The NetSaint box is on both networks. ------------------------------------------------------- This SF.NET email is sponsored by: FREE SSL Guide from Thawte are you planning your Web Server Security?
