Hi People,
I configured bonding (mode=1 - active-backup) and it seems to work properly but there's on thing which maybe I'm missing. Two network cards are used, as far as I understood one is the master (eth0) and the other one (eth1) is the slave. Testing the job I found that when eth0 goes down the bond0 interface still replies to the IP requests whereas if the eth1 goes down the bond0 doesn't work anymore though the it's up and running.
I also tried using the mode=3 (broadcast) which seems to be the other choice for multiple switch topology network but I have the same problem. What I simply need is a fault tolerance only configuration where one network card is connected to one switch and the other one to another switch.
Any advice?
Cheers, Jan
No advice about it? I tried several configuration but nothing has changed so far. Actually I did some simple changes but eventually it doesn't work correctly yet. The slave interfaces are eth0 and eth2 (eth1 si used for another purpose). The problem is now that when eth0 is switched off, the bond0 interface doesn't reply. What hell of bonding is this???
