Hello.
We have 2 servers using X70 nics (Debian Jessie, Kernel 4.14.15).
On each interface we have two ip on same subnet.
Randomly, the secondary ip address doesn’t answer to arp request anymore.
The only solution we have to fix the problem is to manually send arp announcements over the network using a script (while true, sendarp).
There is no proxy arp on neighbors.
# ethtool -i eth0
driver: i40e
version: 2.1.14-k
firmware-version: 6.01 0x80003485 1.1747.0
bus-info: 0000:82:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes
This issue occurs on both servers, and we have same software configuration on a lot sites, and the problem appear only when there is X710 nics.
Anyone already had this problem ?
Kind regards
