i had a strange experience with my call manager, my CUCM v6 rebooted and refuse to see the gateway IP, thinking of what might have happened, i placed it on DHCP, it did not pick up any address ( or so it seemed ) then i reconfigured it with the original IP address again, but this time, it came out with an onformation that it can't confirmed if that IP is in use on the network or not, and so, failed.
since then i have not been able ti assign IP address on eth0. someone please help me climb this mountain
