I am trying to create a channel-group so that I can use 4x1gig connections from a 3560-x to my core a 4507r. When i set the ports the 3560 shows them as suspended. here is the sh run from the ports. I know that I have gi1/4 on the 3560 shutdown right now and I only have one of the prots cabled right now while I try to get the config working. Thanks!

Hi,
Also make sure the encapsulation and native vlan is same at both ends.
See the below example configs on my 4507.
interface Port-channel1
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport mode trunk
interface GigabitEthernet3/30
description xxxxxxxxxxxxxxx
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport mode trunk
channel-group 1 mode on
!
interface GigabitEthernet3/31
description xxxxxxxxxxx
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport mode trunk
channel-group 1 mode on
Hope this will help you.

Everything MUST be the same @ both ends of the link speed/duplex etc. Also you cannot bring an EtherChannel up unless both sides are up/up!

Both ports are set to auto/auto for duplex and speed. They both show a-full and a-1000.

I set duplex full and speed 1000 on both prts then did a shut/no shut on each and they come up as suspended.
