Re: Bondging, Bridging, Vlan-ing, Oh My

Dan,

I captured the debug output like you requested. The entire file is
available at the public link
https://docs.google.com/file/d/0B2kqfJjZRVw5ZXNhNUItSDZZUzA/edit?usp=sharing.

Looks like the interesting part starts at line 96:

NetworkManager[774]: <warn> (vlan25): No support for VLANs on
interface bond0 of type Bond
NetworkManager[774]: <warn> (vlan25) failed to determine virtual interface name
NetworkManager[774]: <warn> (vlan25): No support for VLANs on
interface bond0 of type Bond
NetworkManager[774]: <warn> (vlan25) failed to determine virtual interface name
NetworkManager[774]: <warn> failed to allocate link cache: (-10)
Operation not supported

After I wrote to the mailing list the other day, I ended up changing
my configuration as a temporary workaround. The configuration is now
em1 ---> vlan25 ---> kg25

Basically the bond and em2 were removed, and the configurations were
minimally changed. This new config works perfectly, but I would still
like to get the bond setup.

Thanks,
Justin
