Re: Many lost connexion on procurve
Hi
Its really hard to answer unless we have a good understanding of your topology.
Some few advices,
- Update to latest firmwares.
http://www.hp.com/rnd/software/switches.htm
- Make sure you have a loop free topology, and enable Spanning-Tree if needed.
- Check for any Broadcasts happens in your network (any kind of broadcast).
- Enable Logging on the switches, and install any free Syslog servers softwares:

That will be very helpful for you to debug and troubleshoot.
Good Luck !!!

Re: Many lost connexion on procurve
Hi,
I found my probleme and i solved it.
On looking eventlog by Telnet, i see :
Port B7 is Blocked by LACP
Soluition: Desactivate LACP
On command line write :
CONFIG [ENTER]
Int_B1-B24 [ENTER]
NO_LACP [ENTER]
WR_MEM [ENTER]
--------------
LACP is for control trunking and cause this lost connexion.
Bye and thank's
