Trunk between blade Switch Cat.3020 and Cat4507

Hello everybody,

i got a HP-Enclosure containing a Catalyst Blade Switch 3020 for HP with following image (cbs30x0-lanbase-mz.122-25.SEF1.bin) on it. On remote site a got a Catalyst 4507 with the cat4500-ipbasek9-mz.122-31.SGA1.bin image on it. I try to establishe a fiber trunk between those devices using SFP GBIC's on both sides.

Configuration on NodeY (Blade Switch Cat.3020) has following configuration:

interface GigabitEthernet0/17

description FO Channel to NodeX

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 1,419,1000-1005

switchport mode trunk

media-type sfp

Configuration on NodeX (Cat.4507) has following configuration:

interface GigabitEthernet3/3

description FO Channel to NodeY

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 1,419,1000-1005

switchport mode trunk

logging event link-status

udld port disable

Current Situation:

It's not possible to establish a trunk between teh Cat.3020 and the Cat.4507. If i replace the Catalyst 4507 with a simple Catalyst 2940 (containing same configuration) the trunk will established as expected.

I ask you:

Does anybody has some knowledge as well as a possible fix about my depicted problem ?

Thank you very much for your feedback

kind regards

stephan
