G700 connected to a HP Procurve 1

[colby007]

Hi all,

I've got a G700 connected or trying to connect to a HP Procurve gigabit switch. I can only get the two connected at 10MB Full, anything above that and the two refuse to connect. I've had to put a cisco switch in between the two to get it to run at 100MB Full. I can see both HP and Avaya blaming each other if I pass this to either of them.Has any one come across this or been able to resolve this?

use an ethernet crossover (reversing) cable(s), then you should be able to setup the port on the G700 to 100MB / Full
(this is done in the G700 stack processor, "set port negotiation 10/1 disable", "set port negotiation 10/2 disable") once the ports have autonegotiation disabled, they default to 100MB / Full.

You could also setup a "redundancy pair" for the 2 LAN ports, so if a port locks up or someone unplugs one of the cables from the G700, it still keeps working. Thats also done in the G700 stack processor "set port redundancy 10/1 10/2 on LAN-Redunancy"), and you may also want to set the fallback times as well....

Then set your HP switch to lock at 100MB / Full as well, and as long as you have an ethernet crossover/reversing cable, it will work.

Hi Mitch,

I tried that, apparently the HP is intelligent enough to identify the crossed pins but i tried with both a striaght through cable and a crossed cable anyway. We've also got redunancy and got a link to the gig HP switch from both G700's but we just can't get the 100MB Full. We've nailed down the G700 stack to 100MB full turned off auto neg and no joy.

Both sides must be hard configured if one side is (highly recommended) and you must use the cross over cable. Some switches disable polarity detection when the port is hard configured.

If it works like this with the Cisco then it is something in the HP. You keep calling it a gig switch. Does it support 100MB too? Some gig switches only support gig and the 10mb working may be a fluke.

We've had the same issue with a G700 and HP 5400. It is a known issue and HP is supposed to be releasing a special GBIC to resolve. You can read about it in the following document, page 69.
