Description of problem:
If you have a bonding interface (e.g. bond0) and you tag a vlan interface over top of that bond (e.g. bond0.2), all untagged traffic over that interface will cease to function and only the tagged traffic will be sent out.
A tcpdump of the bonded interface will show the outbound traffic. A tcpdump of the actual physical interface will show nothing.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. create bond0 and assign IP address
2. create bond0.2 and assign IP address
Actual Results: The box stopped passing traffic over the bonded interface, passing traffic only over the vlan.
Expected Results: Traffic should pass both over the non-vlan bonded interface and the vlan.
The problem and a patch for it is outlined in this e-mail:
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
