I do not see any dropped packets.
In syslog I have a lot of these:
[10292.612017] bonding: bond0: Warning: Found an uninitialized port
Attaching my /proc/net/bonding/bond0 & ifconfig outputs
** Description changed:
Configuring an 802.3ad bond doesn't appear to work correctly. The following entry in /etc/network/interfaces should configure an 802.3ad bond between interfaces eth2 and eth3:
#auto bond0
iface bond0 inet static
- address 10.191.62.2
- netmask 255.255.255.0
- broadcast 10.191.62.255
- bond-slaves eth2 eth3
- bond-primary eth2 eth3
- bond-mode 802.3ad
- bond-lacp_rate fast
- bond-miimon 100
+ address 10.191.62.2
+ netmask 255.255.255.0

+ bond-slaves eth2 eth3
+ bond-primary eth2 eth3
+ bond-mode 802.3ad
+ bond-lacp_rate fast

However, after booting the system, we have:

I can ping 10.191.62.2 after making the above changes. So, either I am
configuring /etc/network/interfaces incorrectly or ifupdown/ifenslave is
doing the wrong thing.
Note also the number of dropped packages on bond0. Why should I see any
dropped packages on the bond0 interface?
