Re: ReadyNAS 4312 bonded interface MAC address problem
Hi,
I am seeing an issue with bonding and MAC addressing on the 6.7.5 release.
Connected 2 x FC ports e4 and e5 to a M4300-12x12F stack of 2 switches.
Connected 2 x CAT5 ports e0 and e1 to a M4300-12x12F stack of 2 switches.
Configured e0 and e1 as bond0, and a vlan bond0.195 and bond0.200 LACP 3+4
Configured e4 and e5 as bond1, and a vlan bond1.198 and bond1.199 LACP 3+4
When I check the device I see duplicate MAC addresses on the bond, which I would not expect, and this is causing a problem on the switch and network.
ReadyNAS MAC
ReadyData MAC
It may be related, but I am also having an issue getting the IP address to stick to the bonded vlan interface. I can go into the interface and set a static IP, and apply the ip, and it stays until I do a reboot of the device. After reboot the device is reverting to DHCP on the bonded interfaces.
I have ReadyData devices with the same configuration, and don't see the same issue. Yes the configuration on the switch for the LAG's is exactly the same as the working ReadyData san's.
Can you confirm what behaviour I should expect.

What else would you expect? What problem are you experiencing exactly?
It's expected that the bond interface use the same MAC for the separate VLANs. I don't see what kind of problem it should cause. They're different VLANs, so different Layer 2 networks. In the MAC address table of each switch, you'll have an entry with that MAC address for both VLANs. The forwarding decision is based on the entry in the relevant VLAN.
If you're using /24 subnets, your configuration is incorrect, same Layer 3 network on different Layer 2 networks.

That is a problem of its own. I'm not too sure how to tackle that. Maybe an OS Reinstall? Did you have a look at the logs, is there any clues?

Look where? ^^
The only extract you gave was:

Create a second VLAN interface of the bond, is the MAC address different?
Again, I don't think having the same MAC address on two logical interfaces on two separate VLANs is an issue in any way. Can you clarify what you think is the issue?
