When the bond status are flapping, it might be necessary to check what the kernel sees. This article describes some useful commands to check Bond status around OVS

Instructions

# ovs-appctl bond/list

 

# ovs-appctl bond/list
 
 bridge  bond    type            slaves
 xapi0   bond0   balance-slb     eth2, eth1
Bond show:
# ovs-appctl bond/show bond0
 
 bond_mode: balance-slb
 lacp: off
 bond-hash-algorithm: balance-slb
 bond-detect-mode: carrier
 updelay: 31000 ms
 downdelay: 200 ms
 next rebalance: 6240 ms
 
 slave eth2: disabled
 
 slave eth1: enabled
        active slave
Bond LACP show
Gives actor (XS) and partner (physical switch) information.

To get more information about each bond

         # ovs-appctl lacp/show bond0
