hi,
hope that someone can help.
I ran into port channel issue when trying to add 4 port Quantum Dxi server into a port channel in 3750 stack.
Configs looks ok:
interface Port-channel6
description qdx-server
switchport access vlan 3
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
end
all four ports configured as follows
interface GigabitEthernet1/0/7 , 1/0/5 , 2/0/7 and 2/0/8
description qdx-server-ethx
switchport access vlan 3
switchport mode access
spanning-tree portfast
spanning-tree bpduguard enable
channel-protocol lacp
channel-group 6 mode active
end
all ports joined the channel except Gi 1/0/5 - it got suspended once joined the port channel
From the debug I got the following:

Checked and compared the config from another server, all looks OK.. I tried to search the error message in bold, but can't find any.
Can anyone shed a light?
Many thanks.
