Problem with LACP between two Switches...
We have a 5 Stack-Switches (Aruba 2930M) where all connections are centralized (even if don't do routing). In the other side a couple of Aruba-2930F. Check the picture to see the ports connection:
Here the configurations:
Stack Aruba 2930M:
***********************
trunk 2/A3 trk11 lacp
trunk 4/A3 trk12 lacp
spanning-tree Trk11 priority 4
spanning-tree Trk12 priority 4
spanning-tree mode rapid-pvst
spanning-tree priority 4
Aruba-2930F (A/B):
***********************
trunk 49-50 trk1 lacp
trunk 51-52 trk2 lacp
spanning-tree Trk1 priority 4
spanning-tree Trk2 priority 5
spanning-tree mode rapid-pvst
spanning-tree priority 6
As you can see both Aruba-2930F are connected to Aruba 2930M by the port 50 and they are UP AND RUNNING. When we disconnect one of those ports 50, what I hope is that port 52 is activated, but this doesn't happen ... Since it is still blocked by LACP ...
Any idea?
Many thanks in advance.

Re: Problem with LACP between two Switches...
Hello
Can i ask first why you are using trunks with LACP, only for 1 port? The purpose of trunks is to bundle multiple ports together as 1 logical link.
Then can you execute following show command on all the switches: show spanning-tree. Because normally their should be already blocked port somewhere. If we see a blocked port, we know spanning-tree is well configured.
Also if you don't like to work with spanning-tree, you can try to stack those 2 2930F switches with VSF.

Re: Problem with LACP between two Switches...
Hi HP-Browniee... Thanx 4 answer,,,,
About the "show spanning-tree" command in both 2930F's Switches it's the same:

And obviously the 52/Trk2 is being blocking:

XXXXXXXXXX_2# sh time
As I said before ... Currently both switches work by TRK1 (connected by port 50). Now, what I want to achieve is that when one of those ports 50 falls, the TRK2 (port 52) is lifted. But I can not make it work ... What am I doing wrong?

Re: Problem with LACP between two Switches...
What happens when you disable LACP on those ports?
int 52
no lacp
Is it possible to show the full config of your switches? show run

Re: Problem with LACP between two Switches...
I'm not in the same place as the Switches ... I'm 600 kilometers away and in the case that the "NO LACP"command leaves me out of the Switches I would be in trouble LOL
The configurations of SW1 and SW2 are identical (except the IPs ;)):. Both configs are here:

Re: Problem with LACP between two Switches...
But is the port (52) UP between the 2 access switches right now? Because it seems it is not, from what i have seen.
So if that is the case and you disable LACP on that port it will not have impact.

Re: Problem with LACP between two Switches...
Yes i know, so in my opinion when you disable LACP on that port it can only be better right?
I dont see a reason why you would lose the connection to your remote side. maybe a little STP topology change but that will be all.
But better safe then sorry, so it is always better to have someone on side i guess :)

Re: Problem with LACP between two Switches...
LACP is OUT but nothing has changed.... :(
The port is flapping but isn't blocked by the STP or something.... Should not it appear as BLOCKED?
