Cisco shows LACP not enabled on 11.1U2, BCM, 2960X IOS 15.2

[justlikeef]

Trying to get to a LACP Trunk config. First step is just LACP bundle in edge mode (no vlans) and bundle will not form. The FreeNAS side shows it as being active. The switch is reporting that LACP is not enabled on the individual ports. We have tried multiple versions of IOS from 15.0 to 15.2(6)E1. I have about 10 windows servers with the same NICs on the same switch that are negotiating LACP successfully as well as tagging vlans, so the hardware pieces seem to be OK. I have tried configuring from both the GUI and the CL with the same result.

I don't recall, does the 2960X support port mirroring? do you have a hub? I would sniff the PDUs and see if there is an issue in link negotiation.

Either way I have never had any luck with LACP outside of linking matching switches.

EDIT: Derp just run a pcap and take a look with wireshark or tool of your choice.

Turns out that this is a known issue with the Qlogic driver that everyone thought was fixed, but was reintroduced at some point. Looks like it is not going to get resolved any time soon.

Try putting the bxe interfaces into promiscuous mode ( ifconfig bxe0 promisc ), then shut/no shut the switch ports to bring it up. This fixed it for me.
