No link lights when connecting 2 switches

[ninorg]

Does any one know the reason why i can't get both link light to go on when i connect my 2924xl switch and my 5500 switch because i am trying to do trunking?

Are you using a Cross-over cable to link the two switches? Also there are no other link cables between the two either? If you have more that one connected before you config the switch for it, it will shut down one of the links to prevent packet storms.

Yes i am using Cross-over cable and their are no other link cables between the two either.

We do use Fast Etherchannel between a Catalyst 3524 and a catalyst 5000 with for links (400 Mbps).
Hoping it could be useful for you, here are the configs of the two switches.

The config of the Catalyst 3524 uses :


interface FastEthernet0/1
description FASTETHER1
port group 1 distribution destination
spanning-tree portfast
!
interface FastEthernet0/2
description FASTETHER2
port group 1 distribution destination
spanning-tree portfast
!
interface FastEthernet0/3
description FASTETHER3
port group 1 distribution destination
spanning-tree portfast
!
interface FastEthernet0/4
description FASTETHER4
port group 1 distribution destination
spanning-tree portfast

The config of the Catalyst 5000 includes
(the card must permit Fast Etherchannel, old cards don't permit):

set port channel 5/1-4 on
