1> I see various ports that have the following reported in the logs:
I 02/27/08 15:14:14 ports: port B1 is now off-line
I 02/27/08 15:14:17 ports: port B1 is Blocked by LACP
I 02/27/08 15:14:20 ports: port B1 is now on-line
Can somebody give me a brief explanation of what this is and just how bad it potentially is? Is it similar to Cisco's 'port is flapping' issue? What is LACP up to in this case?
2> More importantly, I have HP servers that some are using Team'ed NICs. In the switch, the two ports that the wires are plugged to are showing up as:
A3-Dyn5 100/1000T | No Yes Up 1000FDx off
A9-Dyn5 100/1000T | No Yes Up 1000FDx off
To set up proper monitoring on this port(s), do I select one port, both ports or is it even possible to monitor 2 ports that team'ed NICs are using?
Thank you.
Solved! Go to Solution.

SolutionThere isn't really any significance to the LACP message on the rising edge (offline->online). It's just a single link down/link up event.

Re: New to HP Procurve switches - 2 questions to start with
Thank you for confirming my thoughts on what LACP is and what it does.
I am still looking for an answer to #2:

Just enable monitoring for both ports and make a mirror port as an output.
I don't think teaming has a big effect on monitoring configuration because the NICs are teamed from the server side, and not trunked from the switch side.
Good Luck !!!

no lacp
for each interface that you aren't using for link aggregation and it will cause the connection to come up faster and keep your logs cleaner.
