Blade C3020 connected to 3750

lourdes_campo · ‎10-06-2008

HP Blades connected using C3020 to 3750 worked finelly until an ios upgrade has been made on 3750.

From then the blades are not accesible.

IOS old version on 3750 was 12.3(5). The new one is 12.2(46).

Are there any incompatibility with this ios and the C3020 ?

Regards

Hi,

1.What is the status of uplink from c3020 to 3750.Use "show interface" command on 3750.

2.If it is trunk, may be trunk must have broken

3.Have you tried booting the c3750 with old IOS ??

HTH..rate if helpful..

1 ) Interfaces on 3750 are up as you can see below:

Gi3/0/9 SAP-02 connected trunk a-full a-1000 10/100/1000BaseTX

Gi3/0/10 SAP-02 connected trunk a-full a-1000 10/100/1000BaseTX

...

Gi4/0/5 SAP-01 connected trunk a-full a-1000 10/100/1000BaseTX

Gi4/0/6 SAP-01 connected trunk a-full a-1000 10/100/1000BaseTX

...

2) How can I see if trunk has been broken ? Any messages on log are recorded, so it seems ok.

3) I haven't tried to boot with the old ios because the devices are on production environment and it have to be done under a maintenance window.
