Cat 3550-12G and HP Procurve 4000 switches not connecting @ 1000!!!

Cat 3550-12G and HP Procurve 4000 switches not connecting @ 1000!!!

The 3550-12G is connected from Gig 0/11 (10/100/1000) to an HP Procurve 4000's 100/1000 Base-T Module (part J4115B).

They connect fine using 100 but I need full 1000.

The HP module has only 2 settings: 100 and auto.

I've tried the following settings with these results:

C3550 auto + Hp auto = down/down

C3550 speed 1000 + Hp auto = down/down

C3550 speed 100 + Hp auto = up/up

C3550 speed 100 + Hp 100 = up/up

This URL shows the HP module specifications (part J4115B):

Any ideas?

Is there a standard bug , not sure, I think so

I eventually had the HP 4000m's firmware upgraded but it had no effect. Still couldn't link @ 1000.

Today, I connected the c3550-12G to a different HP (4108) switch equipped with a similar GigE module and the link connected at 1000!!!

Time to RMA the GigE module on the HP 4000m.

Thanks for your interest!

Just an additional information for others out there. I was able to get a Gigabit 1000Base-SX module on the HP 4000M ProCurve switch to work with a WS-G5484 GBIC module on the Cisco 3550-24PWR-EMI switch.
