Description Bob Gustafson 2009-06-29 17:46:09 EDT
Description of problem:

I was having a lot of difficulty in configuring a connection during Anaconda install and after successful boot into Fedora 11. Never got a connection during this period.

I have two single board ethernet interfaces and one quad board.

To reduce complexity, I had only two cables plugged in. While it was still Fedora 10, I copied off some files through my main LAN connection.

After awhile of trial and error network configuration (disabling NetworkManager in the process), I discovered that my eth0, eth1, eth2, eth3, eth4, eth5 were coming out of ports different from what they had been under Fedora 10.

After this nugget of information, I was able to proceed and do a successful network configuration.

Version-Release number of selected component (if applicable):

  # NetworkManager --help gives no version number

How reproducible:

  Tough to go back to Fedora 10 at this point

Steps to Reproduce:
1. Start with Fedora 10 on a system with lots of ethernet ports
2. Write down the phys port -> ethN table
3. Install Fedora 11
4. Write down new phys port -> ethN table
Actual results:

 Tables in step 2 and 4 above, are different

Expected results:

 Tables in step 2 and 4 above, are the same

Persistent MAC -> ifname mappings are created and maintained by udev; it may be that Fedora started doing this only in F-11.

check and configure /etc/udev/rules.d/70-persistent-net.rules
