Ticket #15140 (closed defect: fixed)
Cannot work with MTU sizes larger than 2 KB => Fixed in SVN
|Reported by:||JFMG||Owned by:|
I have the following setup:
- Host OS: Windows 7.
- Guest OS: CentOS Linux 7.
- Bridged adapter:
- Host NIC: Intel(R) 82579LM Gigabit Network Connection. This NIC has jumbo packets (9014 bytes) enabled in Windows.
- Adapter type: any of the three Intel adapter types available.
I set the MTU size to 5000 bytes (using the corresponding "/etc/sysconfig/network-scripts/ifcfg-enp0sx" file) and I succeed ("ip a" command shows it).
Then I try to ping from the guest NIC to the host NIC or vice versa, I can do it with the default ping packet size or even with 2000 byte packet size (which I couldn't before setting the MTU size to 5000 bytes), but not with larger packet sizes. Of course, pinging with larger than 2 KB packets works when I do it between host LAN NICs.
I've tried with a Fedora image and I get the same results.
