Hi everyone, I've "compiled" all your input, here is the output:
The cables are all cat5e, which should be OK. But to be sure I've managed to find a cat6 cable, but as expected, it did not change anything. So the cables are not the problem. Then I added "speed 1000" and "duplex full" to the two port configuration, but: no change. Next step: Try "mode on" -> Does not work because "on" is PAGP which is not compatible with LACP. Go on: Try "switchport nonegotiate" -> No change in behaviour. When the servers are booting (BIOS, not yet OS) then there is no bonding/etherchannel available. Both ports are independent. That should be no problem for the "mode active/passive" and it works as expected, the server can do DHCP/PXE during boot. But it takes a long time until the server gets an IP from DHCP because it takes so long to get the protocol up. >Is your server supporting LACP? During BIOS boot: no While running OS: yes >How are is the bonding configured on the interfaces? During BIOS boot: not configured While running OS: configured with linux bonding (that works fine) Maybe this will stay a mysterium =) I wish everyone good luck in finding the easter-eggs. (Maybe this behavior is a cisco-easter-egg and solved after easter, who knows =) Cheers, Tobias -- Nine Internet Solutions AG, Albisriederstr. 243a, CH-8047 Zuerich Support +41 44 637 40 40 | Tel +41 44 637 40 00 | Direct +41 44 637 40 13 Skype nine.ch_support _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
