Good Morning,
Trying to create a channel group to a UNIX box setup for server backups. Group sets up okay. SH Interface shows it to be a 2gb link. Problem is only getting 1gb throughput. UNIX has two (2) NICs with same MAC and IP, and here is the config on the switch:
interface Port-channel205
description Channel-Group For TSMBCKUP-G-2/35 & 2/36
switchport
switchport access vlan 8
switchport trunk encapsulation dot1q
switchport mode access
no ip address
interface GigabitEthernet2/35
description TSM - CHASSIS 1 - SLOT-7 B (Rack 506)
switchport
switchport access vlan 8
switchport mode access
no ip address
duplex full
channel-group 205 mode on
end
interface GigabitEthernet2/36
description TSM - CHASSIS 1 - SLOT-7 A (Rack 506)
switchport
switchport access vlan 8
switchport mode access
no ip address
duplex full
channel-group 205 mode on
end
Can someone please tell me where I have made my error.
Thanks again for your assistance.

Hello Dave,
member links need to be configured as trunk ports too.
advice:
after the channel is up to modify the list of allowed vlans do it only on the logical port-channel, or you can experience big problems like bridging loops.
for better load-balancing try to use
port-channel load-balance src-dst-port
this is available on some platforms like C6500.
Hope to help
