[Veritas-bu] Gigabit NIC & Win2K SP3 Network Shutdown
2003-02-20 12:12:05
Gentleman,
Here is the fix for the Gigabit NIC. We are getting 5-11Mb/Sec for each
network clients. The Switch is set to use Fast Ether Channel (FEC) Full
Duplex, and Both Broadcom Gigabit NIC is set to use TEAM.
Buffer_Size set to use 32 kilobytes
NET_BUFFER_SZ set to use 32768 (32x1024)
Both Buffers have to match.
Good Luck
Tommy Wu

Good evening Tommy
Tracking tcp/ip errors always seems hard.
Did you see any errors in the windows event logs, either system or
application?
When we were looking at an ms exchange problem, the veritas tech support
folks said that some drivers for interface cards could cause problems.
You might want to check with tech support and dell tech support. Our
problem was not that, but a problem with the motherboard.
Like others, I would ask for a little more info on what you mean by
shutdown. Does all tcpip traffic stop, or just new connections?
Almost everything netbackup does, seems to have a socket connection in
the middle of the action. If you can you might check with the netstat
command and see if you have a large number of socket connections in a
time-wait state.
If so you might want to look at changing the tcp_wait interval. At least
it was a problem/fix on unix.
Good luck and let us know the final fix.
