ILO network Settings / Strange Network Behavior

[Vanessa_14]

Hi I'm experience strange behavior.

Previous my subnetmask was 255.255.255.0.
I extended the subnetmask to 255.255.0.0.
Because I need more IP adresses.

My servers and Clients are in the 192.168.0.x range. My Ilo's I configured in the 192.168.1.x range contected on a seperate Switch that is uplinked to the other server swithes.

I can successfuly ping from a test PC with IP 192.168.1.0 to my ILO's configured with an adres in that range. ALways!

From the servers I somethimes looses connection pinging to 192.168.1.x range.
Resetting the swith where the ILO's are connected to solves the problem again, temporalilly. But after a while the looses again connection...

My server are as stated before configured in the 192.168.0.x range / 255.255.0.0.

I've changed the swithes and experienced the same behaviou where the ILO's are connected so I don't think my swithes are bad.

Al my swithes are Intelligent Cisco Swithes.
Could this be a temporary problem, because some swithes still "think" my subnetmask is 255.255.255.0 instead of 255.255.0.0?
