Hi,
I have few servers that are connected to PC6224 via two NIC's (bonding
on linux, ether-channel on switch). It works for all servers except one.
Switch claims that there are different partner keys on two links, but
there is one server on the other end with one key. I have checked LACP
packets sent by switch, and on one NIC a get partner key 9 and on the
other key 17.
I've upgraded switch to latest firmware and the problem still exists (4
other servers are still working as expected).
All servers have the same kernel and similar hardware setup.
I've tried shutdowning port 1/g1 and ether-channel switches to 1/g7 (on
the linux side Actor key switches to 17).
What else I can do? Any help appreciated.
Configs (before switching to 1/g7):
