Hi All
I am trying to connect two Cisco 3850 stacks using Etherchannel but having issues as they seem to cause an error/failure on the Etherchannel (see attached image), The stacks themselves are connected using StackWise cable and operational.
I am using two different ports (Gi1/0/48 and G2/0/48) from different switches in the stack to form Etherchannel link, the mode configured is ON/ON as recommended by Cisco and forum members.
Sw3 config:
!
interface GigabitEthernet1/0/47, Gi2/0/48
description #Inter-Switch PortChannel (Po1) Link#
switchport mode trunk
channel-group 1 mode on
end
Sw2 config:
!
interface GigabitEthernet1/0/47, Gi2/0/48
description #Inter-Switch PortChannel (Po1) Link#
switchport mode trunk
channel-group 1 mode on
end
One of the suggestion was to use the same ports from the same switches in Stack but that forms a single point of failure which is not acceptable.
Can you please review and let me know your recommendations?
Thanks in advance to the network gurus
