Hi,
I have plugged 2 UTP 1Gb cable on 2 ports of a 3750 switch and 2 ports of a 2960 switch.
I am trying to trunk the 2 switches with a port-channel, but something seems off in my configs since the port-channel reports a speed of 1000Mb/s when I wass expecting 2000Mb/s
Config on Switch1
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet1/0/11
description -empty-
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
!
interface GigabitEthernet1/0/12
description Trunk port to 10.1.255.100 port 24
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
!
