Hello Experts,

Can some please take at the attached configs and help me determine why I can't get the port channels to come up the switches.?

Cheers

Try setting the switch port mode on the physical interfaces to "Trunk"

The interface isn't trunking - its routing...

I've attached full configs of each switch.

Ensure the following requirements are met;

- Configure all LAN ports in an EtherChannel to operate at the same speed and in the same duplex mode.

- LACP does not support half-duplex. Half-duplex ports in an LACP EtherChannel are put in the suspended state. Check if this is the case with "show etherchannel summary"



Try using Pagp; use the template below on both switches


!
no int po1
!
int e2/0
channel-group 1 mode desirable
!
int e2/1
channel-group 1 mode desirable
!
int po1
ip address <address> <mask>
shutdown
no shutdown

Carlton,

please post a "show etherchannel". Also, what model switches are these?

Try changing the mode to "desirable" instead of active.

Hi Gentlemen,

I tried all of your suggestions and it has been suggested it doesn't work because the router is being emulated on Linux box, see version below....
