Pinned topic 802.3ad bonding with ehea

‏2012-02-15T18:26:25Z |
Hey all, I've been doing AIX on P and Linux on x86 for a number of years now, but I'm doing my first Linux on P today.  I am trying to setup 2 bonding interfaces with the 4 built in ehea ports.  It's a new Power7 server, RHEL 5.7.  I am trying to bond ports 1 and 3 in one lacp port channel, and ports 2 and 4 in a 2nd port channel to a different vlan.  When I bring up the bond interfaces, I start getting "An illegal loopback occurred on adapter (ethX).  This is the same setup that I have on a intel linux box.  Mode is set to 4 in the modprobe.conf and /proc/net/bonding/bondX shows that the mode is 802.3ad, but those messages keep scrolling on the console and the network guy says he's not seeing lacp from my side.  Any suggestions?  I though this might be some difference with the hardware, since this works fine on my intel box.  Thanks!

    Hi, Tom!  Everything I've been able to gather says that the EHEA doesn't support link aggregation because of limitations in its built-in switch.  If link aggregation is required, a different ethernet adapter should be used instead.
