Problem with ixgbe and lagg

[Borja Marcos]

Hello,

I am unable to set up a LACP based interface with lagg and a two ports Intel 10 GbE card. 

When not using lagg, the interfaces work. However, an ifconfig shows that media is not properly detected.

ix2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=e407bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
	ether 0c:c4:7a:bd:70:26
	inet 10.0.5.109 netmask 0xffffff00 broadcast 10.0.5.255 
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	media: Ethernet autoselect (Unknown <rxpause,txpause>)
	status: active


I am using copper SFP+ cables, and just in case I have tried two different ones: one from Brocade and another one from Prolabs.

The PCI identifiers are:

% pciconf -lv pci0:130:0:0
ix2 at pci0:130:0:0:	class=0x020000 card=0x061115d9 chip=0x10fb8086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
    class      = network
    subclass   = ethernet

% pciconf -lv pci0:130:0:1
ix3 at pci0:130:0:1:	class=0x020000 card=0x061115d9 chip=0x10fb8086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
    class      = network
    subclass   = ethernet

When plugging the Brocade SFP I get the following message:
ix2: Detected phy_type 13


And creating the lagg interface in debug mode I see this:

Jun  8 13:16:44 e1 kernel: lagg0: link state changed to UP

Jun  8 13:16:46 e1 kernel: ix3: link state changed to UP
Jun  8 13:16:46 e1 devd: Executing '/etc/rc.d/dhclient quietstart ix3’




Any ideas? Maybe lagg is confused because it can’t detect the interface speed?



Thanks!
