Hello. I'm using 10 Gigabit Ethernet cards Intel 82598EB.When I use them for routing, everything is OK.But when I tried to add them to bridge several problems occured.I had already configured bridge from 2 gigabit Ethernet cards intel 82576. I added a single 10-Gigabit interface in there and got following result: - packets are going from gigabyt to gigabyt port without any problems - packets are coming ang going from 10 gigabyt to gigabyt port(ARP request is seen by tspdamp on destination), but the arp response does not reach the source host (ARP response is not seen by tspdamp on the original host). At the same time at the bridge it can be seen by tspdamp that the arp-answer came from the Gigabit port, and thus can be seen that the package left at 10 gigabit ethernet port. - ARP-requests are going from gigabyt port, they are seen by tcpdamp (tspdamp at gigabit port sees an incoming packet, tspdamp 10-Gigabit sees outgoing packet). But these packets are not visible at destination. Everything is OK with the hosts at the ends of bridge , because if you replace the Linux bridge on FreeBSD bridge, the packets arrive. If you are using only 10-Gigabit ports the same problem occurs, incoming packet is seen by tcpdamp on bridge on the incoming 10G interface and outgoing packet seen on an outgoing 10G port , but packets are is not visible at destination. I checked MTU everywhere, everywhere the same. Tried to increase it's value on bridge interfaces- and got nothing. All iptables and ebtables rules are permissive, default policy anywhere is ACCEPT. I'm using Debian with vanilla kernel 2.6.32.2. In what may be the problem? -- WBR Yavetskiy Yuriy ULTI-RIPE _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
