I need a quick sanity check. I am having problems setting up EtherChannel between an HP server and a Cat 2960G switch. I have the switchports in "active", and 802.3ad configured on the server. I can get the bundling working, but whenever the server re-boots, the EtherChannel goes into an inconsistent state: the switch believes the two links are bundled correctly, but the server does not. If I then shut and no shut the Po interface, the bundle comes up correctly on both sides. But clearly I cannot be on hand every time the server guys want to reboot their server.
The HP support guy wants me to moinitor the LACP during the re-boot. I set up debug lacp all, and sent him the results, but he is not happy with that ... he wants a Wireshark trace. Now, is that possible? As far as I can see, LACP uses the IEEE Slow_Protocols_Multicast 01:80:C2:00:00:02, which is link-constrained. That is, it will not be forwarded by any MAC bridge. So presumably that means I will not see it on a SPAN or RSPAN monitor. (That makes sense, because if a link-constrained protocol were seen outside its proper link, it could play havoc with the topology, unless it were hidden inside some encapsulation.)
So, excuse me if I am being thick, but has anyone here ever successfully done a 2-way trace of LACP using Wireshark? If so, how did you do it? Is there some sort of two-ended probe you can put in the cable or something?
P.S. It is so long since I was last on this forum that everything has all changed. It feels like going back to your native country after a 20-year absence.
