So here's what I have... I have a Solaris 11 non-global zone running on a Solaris 11 global. The NGZ is connected to the global zone via exclusive IP with a vnics and an etherstub. The global zone is then connected to a switch to another Solaris 10 box.
The vnics between the Solaris 11 NGZ and GZ use the default 9000 MTU and the Solaris 11 GZ and Solaris 10 box communicate over standard ethernet 1500 MTU. The Solaris 11 GZ is of course configured as a router. Small packet traffic such as ping, ssh, telnet, etc between the 11 NGZ and the Solaris 10 box work just fine. When I try and do large transfers, such as NFSv4 copies, the Solaris 10 box keeps bringing it's physical link up and down (it's an e1000g card). If I change the MTU size to 1500 on the vnics, the problem goes away. So it appears Solaris 10 is choking on the large packets. Which I would expect some issues, but I wouldn't expect the physical link to flap. But the main issue would seem to be, why isn't the Solaris 11 GZ doing path discovery and dropping the MTU size down to 1500? -- This message posted from opensolaris.org _______________________________________________ networking-discuss mailing list networking-discuss@opensolaris.org
