Dear ALL,
my server give me messages like below:

Apr 20 21:33:09 TAISERVER in.routed[175]: [ID 238047
daemon.warning] interface bge3 to 192.168.11.22 turned off

I check with ifconfig,but nothing error that,how can make it solve...thanks for your help.

post the output of:

# ifconfig -a
# cat /etc/hostname.*
# netstat -rn

is bge3 going to a switch or router?

#ifconfig -a

there is only ONE hostname.* file? the output of ifconfig looks ok. so maybe pupp is right and it's a problem with the switch or cable...

what do you get if you force a ping out bge3 to the default gwy? can you ping that gwy?
