Hello Experts,
I am trying to configure Etherchannel to support NIC teaming. The 2 NIC cards
of a VMserver is connected to my 6500 switch on port gi7/18 and 19. I could see
port channel is up and it shows Gi7/18 & 19 as it members. The ports are also
up. But I am unable to have IP connectivity get established from VMserver.
I could get the IP connectivity established only when any of the Interface
Gi7/18 or 19 is made manually down. Could you please anyone help me to resolve
this. Is this anything related to STP. Please find my configuration below.
interface Port-channel1
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
!
interface range GigabitEthernet7/18 - 19
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
end
