Error when using secondary IP in RH AS4 U3 for PE1850 with DRAC.

[Hans_Chen at Dell.com]

We uses "ifconfig eth0:1 192.168.50.7 netmask 255.255.255.0 up" to bind
the secondary IP address to eth0 in PE1850 which has DRAC card.
But from output of ifconfig,  no "RX packets, TX packets" info for the
eth0:1, it shows netmask to be 255.255.255.255.
netstat -i aslo no data for eth0:1.
The eth0:1 can not work if using it as virtual server IP in Apache.
All PE1850 + AS4 U3 all have the same issue, but PE1850+ AS4 is ok.
Somebody told me that maybe it was caused by conflict of NIC driver and
DRAC card in PE1850, is it true?


output of ifconfig and netstat -i
