nic bonding but noarp flag?

Hi,

I've enabled nic bonding (active-backup mode) using four slaves. According to the doc, ifconfig will display which slaves are inactive by showing NOARP. But it is not found anywhere (see below). Any idea? thanks!

If you want to see which interfaces are active and which ones aren't, try this. It will show you which slave interface is currently the active one.

Code:

cat /proc/net/bonding/bond0

It look like your setting is wrong because both slaves receive traffic from peer.
