Hi all,
I have some minor problem with large icmp packets on Intel 82580 Gigabit
Fiber NIC that use igb 3.0.22 driver.
When mtu set to 1500 I can ping remote host with large icmp packets (larger
than 1500)
with no errors and fragmentation is working properly.
When mtu set less than 1500 on interface (e.g 1200) and I am trying to send
icmp packet larger than mtu (e.g 1500)
then icmp reply for last fragment is being dropped.
I noticed that each time icmp reply dropped following counters incremented
by one in ethtool statistic:
rx_long_length_errors
rx_errors
rx_length_errors.
Topology is quite simple, 82580 Gigabit Fiber NIC installed on gateway
gateway host
ip 5.5.5.5 ----------------------------------------- ip 5.5.5.1
mtu 1200 mtu 1500
>From gateway:
# ping -c 1 -s 1500 5.5.5.1
PING 5.5.5.1 (5.5.5.1) 1500(1528) bytes of data.
--- 5.5.5.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms
tcpdump on gateway:
13:47:01.261271 5.5.5.5 > 5.5.5.1: icmp: echo request (frag 32097:1176@0+)
13:47:01.261286 5.5.5.5 > 5.5.5.1: icmp (frag 32097:332@1176)
13:47:01.261417 5.5.5.1 > 5.5.5.5: icmp (frag 52305:28@1480)
tcpdump on host:
11:08:00.234731 IP 5.5.5.5 > 5.5.5.1: icmp 1176: echo request seq
0
11:08:00.234738 IP 5.5.5.5 > 5.5.5.1:
icmp
11:08:00.234755 IP 5.5.5.1 > 5.5.5.5: icmp 1480: echo reply seq
0
11:08:00.234760 IP 5.5.5.1 > 5.5.5.5: icmp
Ping of small icmp requests than do not need fragmentation is working
properly.
I can move large files over TCP transport - looks like problem only with
icmp fragmentation.
Any advice?
Thank you for help,
Igor
