C3KX-NM-10GT 3750X

Hi Team,

my end-customer have 2x WS-C3750X-24T-L   and also 2x C3KX-NM-10GT. The switchs are working as a stack, I can't get link up in the Tengig interfaces. We're using CAT6a cables with just 3 meters. The cable worked between two servers with 10g nics.

It seems to me that the issue is the 10GT modules. When I reload the frulink I get the errors below:

Can't get the driver hwdb = 0x62D4530 (DTVR-3750X-2)

Failed to initialize Aquantia PHY.  (DTVR-3750X-2)


Mar 30 02:00:12.797: %PLATFORM-6-FRULINK_INSERTED: FRULink 10GT module inserted in Switch 2. (DTVR-3750X-2)Can't get the driver hwdb = 0x611B524

Failed to initialize Aquantia PHY.

Can't get the driver hwdb = 0x611D478

Failed to initialize Aquantia PHY.

If it was just one module and one switch I would think that is hardware, but in two different switchs and modules...

I've tested two different versions:

15.2(1)E1 and 15.0(2)SE5

- reload the entire stack;

- put the switch in standalone;

- re-seat the module;

- tried to enable ipservices license;

Nothing worked.

Any help would be great.

Thank you.

The problem only happend in the slave switch, the 10GT module in the master swicth is working and I can use the tenG interface.

Hi Gagan,in our case he had

Hi Gagan,

in our case he had to RMA both switches. If you can use the 10GT module in the slave switch without problems in the master, I would say that you will need to ask for an RMA of that slave switch.
