Finally i've simply added manually to /etc/network/interfaces 'mtu 9000' to all related interfaces (phisical, bond, bridge) and now Jumbo Frames works as expected: root@tessier:~# ping -I vmbr2 -s 8500 -M do 10.5.252.1 PING 10.5.252.1 (10.5.252.1) from 10.5.252.8 vmbr2: 8500(8528) bytes of data. 8508 bytes from 10.5.252.1: icmp_seq=1 ttl=64 time=0.712 ms 8508 bytes from 10.5.252.1: icmp_seq=2 ttl=64 time=0.770 ms 8508 bytes from 10.5.252.1: icmp_seq=3 ttl=64 time=0.722 ms 8508 bytes from 10.5.252.1: icmp_seq=4 ttl=64 time=0.772 ms ^C --- 10.5.252.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.712/0.744/0.772/0.027 ms root@tessier:~# ping -I vmbr1 -s 8500 -M do 10.5.251.1 PING 10.5.251.1 (10.5.251.1) from 10.5.251.8 vmbr1: 8500(8528) bytes of data. 8508 bytes from 10.5.251.1: icmp_seq=1 ttl=64 time=0.783 ms 8508 bytes from 10.5.251.1: icmp_seq=2 ttl=64 time=0.782 ms 8508 bytes from 10.5.251.1: icmp_seq=3 ttl=64 time=0.778 ms 8508 bytes from 10.5.251.1: icmp_seq=4 ttl=64 time=0.781 ms ^C --- 10.5.251.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.778/0.781/0.783/0.002 ms while does not work for non-jumbo interface, as expected: root@tessier:~# ping -I vmbr0 -s 8500 -M do 10.5.1.3 PING 10.5.1.3 (10.5.1.3) from 10.5.1.8 vmbr0: 8500(8528) bytes of data. ping: local error: Message too long, mtu=1500 ping: local error: Message too long, mtu=1500 ^C --- 10.5.1.3 ping statistics --- 2 packets transmitted, 0 received, +2 errors, 100% packet loss, time 1007ms Good, thanks to all! Still no hint on further optimization via ethernet parameters manipulation, eg via ethtool? -- dott.
