Procurve 2524 gigabit transeiver problem

Procurve 2524 gigabit transeiver problem

Hi all:

I am trying to connect some procurves 8000m and 2524. I am using gigabit modules on all of them. All have the last firmware release 9.16 and 5.17 respectively. I use the auto negotiate setting on both switches. Yet some of the links work and others don't. These switches are connected in a standard star topology with no loops.

I also found that when the 2524 switches were using the 5.09 firmware the negotiation was done correctly and everything worked fine Have any one encountered this problem before?

TIA,
Carlos

Re: Procurve 2524 gigabit transeiver problem

Maybe it's a good ideea to force 1000 Mbps, FDx at both ends of the up-link. Try this and see if you have any more problems. This is what HP has put on paper for my new 4108GLs:

>>>Connectivity Note Regarding Gigabit-SX and -LX Port Settings for Links Between an HP
Series 4100GL Switch and Other Switch Models:

In the HP 1600M/2400M/2424M/4000M/8000M switches, and also in other vendors' switches, the default port mode setting for the Gigabit-SX and Gigabit-LX ports is forced 1000FDx (Gigabit full-duplex). However, the default port mode for the Gigabit-SX and -LX ports in the HP 4108GL is Auto. In earlier software releases, the HP 4108GL tolerated this mismatch and allowed SX and LX links with these other switches to exist. The HP 4108GL (when running software release G.04.04 or greater) now complies with the Gigabit-SX and -LX standard that disallows linkbeat to be enabled when there is a mismatch. (The HP 4104GL, introduced with software release G.05.01, also complies with this requirement.) Thus, mismatched links between Gigabit-SX and -LX ports on an HP Series 4100GL switch and the HP 1600M/2400M/2424M/4000M/8000M switches or other switches that were formerly allowed will now fail. To avoid this problem either reconfigure the Gigabit-SX and -LX ports to Auto on the HP 1600M/2400M/2424M/4000M/8000M switches or other switches, or reconfigure
the Gigabit-SX and -LX ports on the HP Series 4100GL switches to 1000FDx.

This really helped me to make my 4000Ms and 8000Ms to talk to brand-new 4108GLs.
