Got it Robert, It was my mistake, I put post-up instead of pre-up, now it changed ok, I'll do new tests with this config and let you know.
Regards,
German

Hi Robert,Thanks for the response. I was configured as 'datagram', so I try to changed it in the /etc/network/interfaces file and add the following:
## IB0 PUBLIC_CEPH
auto ib0
iface ib0 inet static
address 172.23.17.8
netmask 255.255.240.0
network 172.23.16.0
post-up echo connected > /sys/class/net/ib0/mode
post-up /sbin/ifconfig ib0 mtu 65520
## IB1 CLUS_CEPH
auto ib1
iface ib1 inet static
address 172.23.32.8
netmask 255.255.240.0
network 172.23.47.254
post-up echo connected > /sys/class/net/ib1/mode
post-up /sbin/ifconfig ib1 mtu 65520then reboot, but when it come up again, the mode is still saying 'datagram' instead of 'connected', any idea?Regards,German

Are you using unconnected mode or connected mode? With connected mode
you can up your MTU to 64K which may help on the network side.
