I have a Dell R710 running Solaris 10.
The server was running fine but all of a sudden dropped off the network.
We have tried everything physical - cables ports etc. No luck
We even tried configuring the unused ports on the server - no luck.
ifconfig looks noemal. No error messages....
The weird part is that if I put the interface into DHCP mode, it will pull an IP addy but you cannot ping from the server out or from the network to the server. You can ping the server itself from the console and it says its alive.
Check ifconfig -a shows UP & RUNNING with correct IP and netmask : ifconfig -a
check netstat -rn for correct routing table and defaultrouter. : netstat -rn
snoop on interface to verify traffic flow : snoop -d e1000g0
check for newer network interface driver patches.
