Configuring eth1 to be in promiscuous mode

[AHKAPLAN at PARTNERS.ORG (Kaplan, Andrew H.)]

Hi there -- 

I want to have eth1 on my system run in promiscuous mode. I modified the
/etc/sysconfig/network-scripts/ifcfg-eth1 file to read as follows:

DEVICE=eth1
BOOTPROTO=
...
ONBOOT=
TYPE=Ethernet
...

I reboote the system and when I did an /sbin/ifconfig, eth1 appeared without
an ip address. I did a check in the /var/log/messages file and while eth0 is 
in promiscuous mode, eth1 does not appear to be so. 

Is there something else I need to do? Thanks.
