Hi Flavio,
The net topo we have as below:
The eth1-4 connect to the same one switch, and for teamd with loadbalance
mode, p1/2 will have the same MAC(changed by libteam), and p3/4 will
have the same MAC.
+------------------------------+
| switch |
+------------------------------+
p1 p2 p3 p4
| | | |
| | | |
eth1 eth2 eth1 eth2
| | | |
+-----+ +------+
A | | B
+------+ +-------+
As we know, for bonding driver, the 802.3ad mode requires that the
switch have the appropriate ports configured as an 802.3ad
aggregation, what about libteam with loadbalance mode?
Can you show me some config to do for the switch with loadbalance
mode? And what about lacp mode?
Thanks,
Best Wishes,
Wenhua
