[ale] NIC troubles

[Ryan Fish]

Hello all,

After completing a server move from one DC to another I have been putting out small fires.  This one, though, has left me scratching my head so far...

OS: RHEL ES3

There are two NICs in this server: one for public and one for private.  For some reason it appears there is a conflict between the second IP on the first NIC (eth0:0) and the only IP on the second NIC (eth1).  See below:

eth0:0    Link encap:Ethernet  HWaddr 00:0F:1F:04:76:89  
          inet addr:209.168.xxx.xxx  Bcast:209.168.xxx.xxx  Mask:255.255.255.240
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:4678729 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4455288 errors:38 dropped:0 overruns:0 carrier:0
          collisions:374563 txqueuelen:1000 
          RX bytes:1819725445 (1735.4 Mb)  TX bytes:950192933 (906.1 Mb)
          Interrupt:16 

eth1      Link encap:Ethernet  HWaddr 00:0F:1F:04:76:8A  
          inet addr:192.168.3.xxx  Bcast:192.168.3.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:4678729 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4455288 errors:38 dropped:0 overruns:0 carrier:0
          collisions:374563 txqueuelen:1000 
          RX bytes:1819725445 (1735.4 Mb)  TX bytes:950192933 (906.1 Mb)
          Interrupt:17

As can be seen by the MAC addresses these are not the same NIC.  However, all of the stats (RX/TX/collisions, etc) are exactly the same between them while eth0 is behaving nicely.

Any suggestions on why this happening and where I should look to correct it?

Thank you in advance.
