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.

- 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
