I have hit that same issue. The solution is the restart all of
networking. I don't know why ifconfig eth0:1 up won't work with virtual
interfaces. It just won't.

&gt; If you take eth0:0 down does eth1 still give errors and collisions?  
&gt; And, vice versa?  Let's prove your interfaces are working separately 
&gt; without problems first.

&gt; &gt;Hello all,
&gt; &gt;
&gt; &gt;After completing a server move from one DC to another I have been putting
&gt; out small fires.  This one, though, has left me scratching my head so far...
&gt; &gt;
&gt; &gt;OS: RHEL ES3
&gt; &gt;
&gt; &gt;There are two NICs in this server: one for public and one for private.  For
&gt; some reason it appears there is a conflict between the second IP on the
&gt; first NIC (eth0:0) and the only IP on the second NIC (eth1).  See below:
&gt; &gt;
&gt; &gt;eth0:0    Link encap:Ethernet  HWaddr 00:0F:1F:04:76:89  
&gt; &gt;          inet addr:209.168.xxx.xxx  Bcast:209.168.xxx.xxx
&gt; Mask:255.255.255.240
&gt; &gt;          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
&gt; &gt;          RX packets:4678729 errors:0 dropped:0 overruns:0 frame:0
&gt; &gt;          TX packets:4455288 errors:38 dropped:0 overruns:0 carrier:0
&gt; &gt;          collisions:374563 txqueuelen:1000 
&gt; &gt;          RX bytes:1819725445 (1735.4 Mb)  TX bytes:950192933 (906.1 Mb)
&gt; &gt;          Interrupt:16 
&gt; &gt;
&gt; &gt;eth1      Link encap:Ethernet  HWaddr 00:0F:1F:04:76:8A  
&gt; &gt;          inet addr:192.168.3.xxx  Bcast:192.168.3.255  Mask:255.255.255.0
&gt; &gt;          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
&gt; &gt;          RX packets:4678729 errors:0 dropped:0 overruns:0 frame:0
&gt; &gt;          TX packets:4455288 errors:38 dropped:0 overruns:0 carrier:0
&gt; &gt;          collisions:374563 txqueuelen:1000 
&gt; &gt;          RX bytes:1819725445 (1735.4 Mb)  TX bytes:950192933 (906.1 Mb)
&gt; &gt;          Interrupt:17
&gt; &gt;
&gt; &gt;As can be seen by the MAC addresses these are not the same NIC.  However,
&gt; all of the stats (RX/TX/collisions, etc) are exactly the same between them
&gt; while eth0 is behaving nicely.
&gt; &gt;
&gt; &gt;Any suggestions on why this happening and where I should look to correct
&gt; it?
&gt; &gt;
&gt; &gt;Thank you in advance.
&gt; &gt;-Ryan
